    \title A Quick Tour of Qt Creator

    The labeled screenshot below shows some of the components of Qt Creator, in
    \gui Edit mode.

    \image qtcreator-breakdown.png

    \section1 The Mode Selectors

    When working in Qt Creator, you can be in one of six modes: \bold Welcome,
    \bold Edit, \bold Debug, \bold Projects, \bold Help, and \bold Output.

    Mode selectors allow you to quickly switch between tasks: editing, browsing
    the Qt Creator manual, setting up the build environment, etc. You can
    activate a mode by either clicking on its mode selector, or using the
    \l{keyboard-shortcuts}{corresponding keyboard shortcut}. Certain actions also
    trigger a mode change, e.g., \gui{Debug}/\gui{Start debugging} switches
    to the \gui Debug mode.

    \list

    \o \gui{Welcome mode} - Displays a welcome screen allowing you to quickly
    load sessions or recent individual projects. This is the mode displayed
    when Qt Creator is run without command line switches.

    \o \gui{Edit mode} - Lets you edit both project and source files. A sidebar
    on the left provides different views for navigating between files.

    \o \gui{Debug mode} - Provides various ways to inspect the state of the
    program while debugging. See \l{Qt Creator and Debugging} for a hands-on
    description of how to use this mode.

    \o \gui{Projects mode} - Lets you configure how projects can be built and
    executed. Under the list of projects, there are tabs to configure the
    build, run, and editor settings.

    \o \gui{Help mode} - Shows all documentation registered by Qt Assistant,
    such as the Qt library and Qt Creator documentation.

    \o \gui{Output mode} - Lets you examine various data in detail, for example
    build issues as well as compile and application output. This information
    is also available in the output panes.

    \endlist


    \section1 The Output Panes

    The task pane in Qt Creator can display one of four different panes:
    \gui{Build Issues}, \gui{Search Results}, \gui{Application Output}, and
    \gui{Compile Output}. These panes are available in all modes.


    \section2 Build Issues

    The \gui{Build Issues} pane provides a list of issues, e.g., error messages
    or warnings that need to be fixed. It filters out irrelevant output from
    the compiler and presents the issues in an organized way.

    \image qtcreator-build-issues.png


    \section2 Search Results

    The \gui{Search Results} pane displays the results for global searches such
    as searching within a current document, files on disk, or all projects. In
    the screenshot below, we searched for all occurrences of \c{textfinder}
    within the \c{"/TextFinder"} folder.

    \image qtcreator-search-pane.png


    \section2 Application Output

    The \gui{Application Output} pane displays the status of a program when
    it is executed, and the debug output, e.g., output from qDebug().

    \image qtcreator-application-output.png


    \section2 Compile Output

    The \gui{Compile Output} pane provides all output from the compiler. In
    other words, it is a more detailed version of information displayed in the
    \gui{Build Issues}

    \image qtcreator-compile-pane.png


    \section1 Qt Help Integration

    Qt Creator comes fully integrated with all of Qt's documentation and
    examples via the Qt Help plugin. To view the documentation, switch
    to the \gui{Help} mode. To obtain context sensitive help, move the text
    cursor to a Qt class or function and press \key{F1}. The documentation
    is displayed in a pane on the right, as shown in the screenshot
    below. If there is enough vertical space, it is shown in the
    fullscreen help mode.

    \image qtcreator-context-sensitive-help.png

    External documentation provided by the user can be used to augment or
    replace the documentation shipped with Qt Creator and Qt.


    \section1 Qt Designer Integration

    Qt Creator is fully integrated with Qt Designer to help you design user
    interface forms like you would with the standalone version. The Qt
    Designer integration also includes project management and code completion.
    For more information on Qt Designer, see
    \l{http://doc.trolltech.com/designer-manual.html}{The Designer Manual}.

    \image qtcreator-formedit.png


    \section1 Keyboard Navigation

    Qt Creator caters not only to developers who are used to using the mouse,
    but also to developers who are more comfortable with the keyboard. A wide
    range of \l{keyboard-shortcuts}{keyboard} and
    \l{Navigating Around Your Code with Locator}{navigation} shortcuts
    are available to help speed up the process of developing your application.

    \title The Code Editor

    Qt Creator's code editor is designed to aid the developer in creating, editing,
    and navigating code. It is fully equipped with syntax highlighting, code
    completion, context sensitive help, and inline error indicators
    while you are typing.

    \section1 Code Editor Configuration

    The screenshots below show the various dialogs within
    which you can configure your editor.

    \endtable

    \section1 Code Completion

    The completion popup shows possible completions to a certain statement.
    These completions include classes, namespaces, functions, variables,
    macros and keywords. Listed below are the icons used in the completion box
    and their meaning.

    \title Project Settings

    \table
        \row
            \i  \note This page describes Qt Creator's support for \c qmake.
                For information on CMake support, see
                \l{CMake Support in Qt Creator}.
    \endtable

    To modify the project settings of your project, switch to the \gui{Projects}
    mode by using the mouse or pressing \key{Ctrl+4}.

    \image qtcreator-projectpane.png

    The project pane is divided into two areas. The currently active settings are
    displayed at the top. The active build and run configuration for all projects
    can be changed there. The bottom area allows you to quickly get an overview
    of the build, run and editor settings as well as the dependencies between your
    projects. It also allows you to edit those settings.

    \section1 Build Settings

    Build configurations allow you to quickly switch between different build
    settings. By default, Qt Creator creates a \bold{debug} and a
    \bold{release} build configuration. Both of these configurations use the
    \l{glossary-default-qt}{default Qt version}. Action items to create, clone,
    or delete build configurations can be found at the top. You can have as
    many build configurations as necessary. To edit settings, click on the
    \gui{Show Details} button. Here you can specify which
    \l{glossary-project-qt}{Qt version} to use to build your project, or whether
    to \l{glossary-shadow-build}{shadow build} the project, for instance.

    \image qtcreator-ppbuildsettings.png

    The build system of Qt Creator is built on top of \c qmake and \c make. The
    settings for \c qmake and \c make can be changed. Qt Creator runs the
    make command using the correct Qt version.

    In the \bold{Build Environment} section you can specify the environment used
    for building. By default, the environment in which Qt Creator was started
    is used and modified to include the Qt version. Depending on the selected
    Qt version, Qt Creator automatically sets the necessary environment
    variables.

    \section1 Run Settings

    \image qtcreator-pprunsettings.png
    Qt Creator automatically creates run configurations for your project.
    These run configurations derive their executable
    from the parsed .pro files. You can also create \bold{custom executable}
    run configurations where you can freely set the executable to be run.

    \section1 Dependencies

    If you have multiple projects loaded in your session, you can configure
    dependencies between them. This affects the build order of your
    projects. To do this:
    \list 1
        \o Select the project for which you want to configure the dependencies.
        \o Go to the \bold{Dependencies} section.
        \o Check the checkboxes to select other projects as dependencies.
    \endlist
    \note This is unrelated to the dependencies inside a qmake project.

    \title Qt Version Management

    Qt Creator allows you to use multiple versions of Qt installed on your hard
    disk and switch between them easily.

    Qt Creator automatically detects if \c qmake is in the environment variable
    \c PATH. This \l{glossary-system-qt}{version of Qt} is referred to as
    \bold{Qt in PATH}. If you use only one version of Qt and it is
    already in your path and correctly set up for command line usage, you do
    not need to manually configure your Qt version.

    Otherwise, you can add your Qt version in
    \gui{Tools > Options... > Qt Versions} on Windows and Linux or
    in \gui{Qt Creator > Preferences... > Qt Versions} on Mac OS X.

    The detailed settings depend on your operating system and on the targeted
    tool chain.

        \table
        \row
            \i \image qtcreator-qt4-qtversions.png
            \i \bold{Linux and Mac OS X}

               On Linux and Mac OS X, set the \gui{path to QMake}
               to the \c qmake binary of the Qt installation. If a Qt is
               found in the \c PATH environment variable, it shows up
               automatically as \gui{Qt in PATH}.

               On both platforms, the platform's GNU Compiler Collection (GCC)
               is used to compile Qt. On Mac OS, the GCC compiler is part of XCode.
               On Linux, the Intel Compiler (ICC) is supported as a drop-in replacement
               for GCC.

        \row
            \i \image qtcreator-qt4-qtversions-win-mingw.png
            \i \bold{Windows and MinGW}

               If you are on the Windows platform and used MinGW
               to compile Qt, you need to tell Qt Creator
               where MinGW is installed. This is done by setting the
               \gui{MinGW directory}.
        \row
            \i \image qtcreator-qt4-qtversions-win-msvc.png
            \i \bold{Microsoft Visual C++}

               If your Qt version is compiled with Microsoft Visual C++'s
               compiler, Qt Creator automatically sets the correct
               environment variables for compilation. The \gui{MSVC}
               drop-down box indicates the internal version number of the
               installed Microsoft Visual C++ tool chains:

               \list
                   \o  \bold{7.1}: Visual Studio 2003
                   \o  \bold{8.0}: Visual Studio 2005
                   \o  \bold{9.0}: Visual Studio 2008
               \endlist

               If you are using the \c{Windows SDK for Windows Server 2008}
               instead of Visual Studio, it identifies as version 9.0.
        \row
            \i \image qtcreator-qt4-qtversions-win-symbian.png
            \i \bold{Symbian}

               If you are using Qt for Symbian and your S60 SDK is registered
               with \c devices.exe, Qt Creator detects the Qt version
               automatically.
               It is shown in the \bold{Auto-detected} section in the options
               dialog.
               You can also manually add Qt for Symbian versions. In this case
               you need to tell Qt Creator the path to the S60 SDK
               it is supposed to use with these Qt installations.
               Add the path to your Carbide C++ install, version 2.0
               or later, if you want to build for the emulator
               (\c WINSCW tool chain).
               If you want to use \c GCCE to build for your device,
               you might need to add the path to the
               \c{CSL ARM Toolchain} directory (\gui{CSL/GCCE Directory}),
               if the compiler is not found in the \c PATH environment
               variable.
        \endtable

    \note By default, projects are compiled with the
    \l{glossary-default-qt}{default Qt version}. You can override this in the
    \gui{build configuration}.

            \i \bold{Creating a new project}

        To create a new project, select \gui{New Project} from the \gui{File} menu.
        You can create one of the following three projects:

        \list
            \o Qt4 Console Application
            \o Qt4 Gui Application
            \o C++ Library
        \endlist

        In this example, we select a \e{Qt4 Gui Application} and click on \gui{OK}.

        \row
            \i \inlineimage qtcreator-intro-and-location.png
            \i \bold{Setting the project name and location}

        Next, we set the project's name and its path. Click on the \gui{Choose...}
        button to browse and select your path.

        Ideally, the path should not contain spaces or special characters.

        \row
            \i \inlineimage qtcreator-select-modules.png
            \i \bold{Selecting the necessary Qt modules}

        Check the check box for each Qt module you want to include into
        your project.

        Since we started a Qt4 Gui Application, the QtCore and QtGui modules are
        set by default, but you are free to add more.

        \row
            \i \inlineimage qtcreator-class-info.png
            \i \bold{Specifying class information}

        Specify the name of the class you want to create. The
        \e{Header file}, \e{Source file} and \e{Form file} fields update
        automatically according to the class name you choose.

        Remember to select the base class for your class, either a

    \title Writing a Simple Program with Qt Creator

    \table
        \row
        \o \note This tutorial assumes that the user has experience in writing
           basic Qt applications, designing user interfaces with Qt Designer
           and using the Qt Resource System.
    \endtable


    In this example, we describe the steps involved in using Qt Creator
    to create a small Qt program, Text Finder. Inspired by the QtUiTools'
    \l{http://doc.trolltech.com/uitools-textfinder.html}{Text Finder}
    example, we write a similar but simplified version of it, as shown
    below.

    \image qtcreator-textfinder-screenshot.png

    \section1 Setting Up Your Environment

    Once you have installed Qt Creator, it detects automatically if Qt's
    location is in your \c PATH variable. If not, please follow the
    instructions in \l{Qt Version Management}.

    \section1 Setting Up the Project

    We begin with a Qt4 Gui Application project generated by Qt Creator. The
    \l{Creating a Project in Qt Creator} document describes this process in
    detail. Remember to select QWidget as the Text Finder's base class. If
    your project is not yet loaded, load it by selecting \gui{File} > \gui{Open}.

    In your project, you have the following files:

    \list
        \o \c{textfinder.h}
        \o \c{textfinder.cpp}
        \o \c{main.cpp}
        \o \c{textfinder.ui}
        \o \c{textfinder.pro}
    \endlist

    The \c{.h} and \c{.cpp} files come with the necessary boiler plate code.
    The \c{.pro} file is also complete.

    \section1 Filling in the Missing Pieces

    We begin by designing the user interface and then move on to filling
    in the missing code. Finally, we add the find functionality.

    \section2 The User Interface

    To begin designing the user interface, double-click on the
    \c{textfinder.ui} file in the \gui{Project Explorer}. This launches the
    integrated Qt Designer.

    Design the form below with:
    \list
        \o \l{http://doc.trolltech.com/qlabel.html}{QLabel}
        \o \l{http://doc.trolltech.com/qlinedit.html}{QLineEdit} (named lineEdit)
        \o \l{http://doc.trolltech.com/qpushbutton.html}{QPushButton} (named findButton)
        \o \l{http://doc.trolltech.com/qtextedit.html}{QTextEdit} (named textEdit)
    \endlist

    \image qtcreator-textfinder-ui.png

    We recommend that you use a \l{http://doc.trolltech.com/qgridlayout.html}{QGridLayout}
    to lay out the label, the line edit and the push button.
    The grid layout and the text edit can then be added to a
    \l{http://doc.trolltech.com/qvboxlayout.html}{QVBoxLayout}.
    If you are new to designing forms with \QD, see the
    \l{http://doc.trolltech.com/designer-manual.html}{Qt Designer Manual}.

    \section2 The Header File

    The \c{textfinder.h} file already has the necessary #includes, a
    constructor, a destructor, and the \c{Ui} object. We need to add a private
    slot, \c{on_findButton_clicked()}, to carry out our find operation. We
    also need a private function, \c{loadTextFile()}, to read and display the
    contents of our input text file in the
    \l{http://doc.trolltech.com/qtextedit.html}{QTextEdit}. This is done with
    the following code:

    \snippet examples/textfinder/textfinder.h 0

    \note The \c{Ui::TextFinder} object is already provided.

    \section2 The Source File

    Now that our header file is complete we move on to our source file,
    \c{textfinder.cpp}. We begin by filling in the functionality to load a
    text file. This is described in the code snippet below:

    \snippet examples/textfinder/textfinder.cpp 0

    Basically, we load a text file using
    \l{http://doc.trolltech.com/qfile.html}{QFile}, read it with
    \l{http://doc.trolltech.com/qtextstream.html}{QTextStream}, and
    then display it on \c{textEdit} with
    \l{http://doc.trolltech.com/qtextedit.html#plainText-prop}{setPlainText()}
    which requires adding the following additional #includes to textfinder.cpp:

    \snippet examples/textfinder/textfinder.cpp 1

    For the \c{on_findButton_clicked()} slot, we extract the search string and
    use the \l{http://doc.trolltech.com/qtextedit.html#find}{find()} function
    to look for the search string within the text file. This is described in
    the code snippet below:

    \snippet examples/textfinder/textfinder.cpp 2

    Once we have both of these functions complete, we call \c{loadTextFile()} in
    our constructor.

    \snippet examples/textfinder/textfinder.cpp 3

    The \c{on_findButton_clicked()} slot is called automatically in
    the uic generated \c{ui_textfinder.h} file by this line of code:

    \code
    QMetaObject::connectSlotsByName(TextFinder);
    \endcode

    \section2 The Resource File

    We require a resource file (\c{.qrc}) within which we embed the input
    text file. This can be any \c{.txt} file with a paragraph of text.

    To add a resource file:
    \list 1
        \o Right-click on \gui{Resource Files} in the \gui{Project Explorer}.
        \o Select \gui{Add New File...}.
    \endlist
    The wizard dialog below is displayed.

    \image qtcreator-add-resource-wizard.png

    \list 3
        \o Enter "textfinder" in the \gui{Name} field. Use the given \gui{Path}.
        \o Click on \gui{Continue}.
    \endlist
    This page is displayed:

    \image qtcreator-add-resource-wizard2.png

    \list 5
        \o Choose to which project you want to add the new file. Select "TextFinder"
        as the \gui{Project}.
        \o Make sure that \gui{Add to Project} is checked.
        \o Click on \gui{Done}.
    \endlist

    Your resource file is now displayed in the resource editor.

    \list 8
        \o Select \gui{Add} > \gui{Add Prefix} from the drop-down list. The prefix we
        require is a slash (\c{/}).
        \o Select \gui{Add} > \gui{Add File} from the drop-down list.
        \o Locate the text file you are going to use. We use \c{input.txt}.
    \endlist

    Once the resource file has been successfully added, the following is displayed:

    \image qtcreator-add-resource.png

    \endtable


    \section1 Setting Up Version Control Systems

    Qt Creator uses the version control system's command line clients to
    access your repositories. To set it up, you must ensure that these command
    line clients can be located via the \c{PATH} environment variable.
    To specify the path to the command line client's executable, go to the settings
    pages in \gui{Tools} > \gui{Options...}.


    \section1 Setting Up Common Options

    The \gui{Version Control > Common} settings page features common settings for
    version control systems, such as commit message line wrapping and checking
    options.

    \gui{Submit message checking script} is a script or program that can be
    used to perform checks on the submit message before submitting. The submit
    message is passed in as the script's first parameter. If there is an error,
    the script should output a message on standard error and return a non-zero
    exit code.

    \gui{User/alias configuration file} takes a file in mailmap format that
    lists user names and aliases. For example:

    \code
    Jon Doe <Jon.Doe@company.com>
    Hans Mustermann <Hans.Mustermann@company.com> hm <info@company.com>
    \endcode

    Notice that the second line specifies the alias \e{hm} and the
    corresponding email address for \e{Hans Mustermann}. If the user/alias
    configuration file is present, the submit editor displays a context
    menu with \gui{Insert name...} that pops up a dialog letting the user
    select a name.

    \gui{User field configuration file} is a simple text file consisting of
    lines specifying submit message fields that take user names, for example:

    \code
    Reviewed-by:
    Signed-off-by:
    \endcode

    These fields appear below the submit message. They provide completion
    for the aliases/public user names specified in the
    \e{User/alias configuration file} as well as a button that opens the
    aforementioned user name dialog.


    \section1 Using Version Control Systems

    The version control sub-menus are in \gui{Tools} menu. The version control system
    managing the current project is displayed here.

    Each version control system adds a pane to the \gui{Application Output}
    panes within which itlogs the commands it executes, prepended by a
    timestamp and the relevant output.

    \image qtcreator-vcs-pane.png


    \section2 Addings Files

    When you create a new file or a new project, the wizard displays a page
    asking whether the files should be added to a version control system.
    This happens when the parent directory or the project is already
    under version control and the system supports the concept of adding files,
    e.g., \bold{Perforce} and \bold{Subversion}. Alternatively, you can
    add files later by using the version control tool menus.

    With \bold{git}, there is no concept of adding files. Instead, all modified
    files must be \e{staged} for a commit.


    \section2 Viewing Diff Output

    All version control systems provide menu options to \e{diff} the current
    file or project: to compare it with the latest version stored in the
    repository and to display the differences. In Qt Creator, a diff is
    displayed in a read-only editor. If the file is accessible, you can
    double-click on a selected diff chunk and Qt Creator opens an editor
    displaying the file, scrolled to the line in question.

    \image qtcreator-vcs-diff.png


    \section2 Annotating Files

    Annotation views are obtained by selecting \gui{Annotate} or \gui{Blame}.
    This displays the lines of the file prepended by the change identifier
    they originate from. Clicking on the change identifier shows a detailed
    description of the file.


    \section2 Committing Changes

    Once you have finished making changes, you can submit them to the version
    control system by choosing \gui{Commit} or \gui{Submit}. Qt Creator
    displays a commit page containing a text editor, where you can enter your
    commit message, and a checkable list of modified files to be included.
    When you are done, click on \gui{Commit} to start committing. In addition,
    there is a \gui{Diff Selected Files} button that brings up a diff view of the
    files selected in the file list. Since the commit page is just another
    editor, you can go back to it by closing the diff view. Alternatively, you
    can view it from the editor combo box showing the \gui{Opened files}.

    \image qtcreator-vcs-commit.png


    \section2 Viewing Versioning History and Change Details

    The versioning history of a file is displayed by selecting
    \gui{Log} (for \bold{git}) or \gui{Filelog} (for \bold{Perforce} and
    \bold{Subversion}). Typically, the log output contains the
    date, the commit message, and a change or revision identifier.
    Click on the identifier to display a description of the change including the diff.

    \image qtcreator-vcs-log.png
    \image qtcreator-vcs-describe.png


    \section2 Using git-specific Menu Entries

    The git sub-menu contains additional entries:

    \table
        \row
            \i  \gui{Stash}
            \i  Stash local changes prior to executing a \bold{pull}.
        \row
            \i  \gui{Pull}
            \i  Pull changes from the remote repository. If there are locally
                modified files, you are prompted to stash those changes.
        \row
            \i  \gui{Branches...}
            \i  Displays the branch dialog showing the local branches at the
                top and remote branches at the bottom. To switch to the local
                branch, double-click on it. Double-clicking on a remote
                branch first creates a local branch with the same name that
                tracks the remote branch, and then switches to it.

    \title Navigating Around Your Code with Locator

    With Qt Creator, navigating to different locations in your project or on
    your disk, e.g., files, classes, methods, etc., is simple using
    \gui Locator -- a smart line edit at the bottom left in Qt Creator
    window.

    \image qtcreator-locator.png

    For example, to open your project's \c{main.cpp} file:
    \list 1
        \o Click on \gui Locator or press \key{Ctrl+K} (Mac OS X: \key{Cmd+K}).
        \o Type in the file name.
        \o Press \key Return.
    \endlist
    The file opens in the editor.

    You can also type part of a file name and use the wildcard characters
    \c{*} and \c{?} to match \e{any} number of \e{any} characters. A list
    of files matching your criteria is displayed.

    \gui Locator allows you to navigate files both on disk and in other
    "locations", which are organized with \bold{Filters}. There are
    filters for:

    \list
        \o  Files anywhere on your hard disk (browsing through the file system)
        \o  Files from a subdirectory structure defined by you
        \o  Files mentioned in your \c{.pro} files, such as source, header
            resource, and \c{.ui} files
        \o  Any open document
        \o  Class and method definitions in your project or anywhere referenced
            from your project
        \o  Help topics, including Qt's documentation
        \o  Specific line in the document displayed on your editor
    \endlist


    Some of these filters require you to activate them by typing an assigned
    \e prefix. This prefix is usually a single character followed by
    \key{Space}. For example, to jump to the definition of the class
    \l{http://doc.trolltech.com/qdatastream.html}{QDataStream}, activate
    \gui Locator. Then type a colon (\key{:}) followed by a \key{Space} and
    the class name.


    Below is a full list of \l{http://doc.trolltech.com/qdatastream.html}
    {QDataStream} related output:

    \image qtcreator-navigate-popup.png


    Filters can be added to provide quick navigation around files in a
    subdirectory structure defined by you. This way, you can acccess files you
    need that are not directly mentioned in your project.
    \list 1
        \o Click the button \image qtcreator-locator-magnify.png
        \o Select \gui{Configure...} from the menu displayed:
        \image qtcreator-locator-customize.png
        \o To create a new filter, select \gui Add from the \gui Configure...
        dialog (\gui Options on Mac Os X).
        \o In the \gui{Filter Configuration} dialog below:
        \list
            \o Give your filter a name.
            \o Select your preferred directories.
            \o Set file patterns with a comma separated list.
            \o Specify a prefix string.
        \endlist
        \image qtcreator-navigate-customfilter.png
        \o Close the dialog.
    \endlist
    \gui Locator searches the directories you selected for files matching
    your file patterns. Information is cached. To update the cached information:
    \list 1
        \o Click the button \image qtcreator-locator-magnify.png again.
        \o Select \gui Refresh.
    \endlist

    The following table lists available filters:

    \table
        \header
            \o  Function
            \o  Key Combination

            \o  Go to a method definition.
            \o  Ctrl+K, m, Space, and the class name
            \o  \image qtcreator-locator-methods.png
    \endtable

    \note By default, if you press \key{Ctrl+K} and do not use a prefix to
    specify a filter, three filters are enabled: \c{o}, \c{l}, and \c{a}.

    \note On Mac OS X, press \key{Cmd+K} instead of \key{Ctrl+K}.

    \title Session Management in Qt Creator

    In Qt Creator, a session is a collection of:

    \list
        \o Open projects with their dependencies
        \o Open editors
        \o Breakpoints and watches
        \o Bookmarks

    When you run Qt Creator, you enter a default session. You can create a new
    session using the \gui{Session Manager...} option, available in the
    \gui{File > Session} menu.


    \image qtcreator-session-manager.png


    To switch between sessions, select \gui{File > Session}. If you do not
    create and select any session, Qt Creator always uses the default
    session.

    \title Qt Creator and Debugging


    \section1 About Debugging with Qt Creator

    Qt Creator does not have its own debugger. Instead, it provides a graphical
    frontend to various debugger engines:

    \table
        \header
            \o Platform
            \o Compiler
            \o Debugger Engine
        \row
            \o Linux, Unixes, Mac OS
            \o gcc
            \o GNU Symbolic Debugger (gdb)
        \row
            \o Windows/MinGW
            \o gcc
            \o GNU Symbolic Debugger (gdb)
        \row
            \o Windows
            \o Microsoft Visual C++ Compiler
            \o Debugging Tools for Windows/Microsoft Console Debugger (CDB)
    \endtable

    The frontend allows you to:
    \list
        \o Go through a program line-by-line or instruction-by-instruction.
        \o Interrupt running programs.
        \o Set breakpoints.
        \o Examine the contents of the call stack, local and global variables, etc.
    \endlist

    Qt Creator displays the raw information provided by the engine
    in a clear and concise manner. This simplifies the debugging process.

    Qt Creator comes with generic IDE functionality: stack view, views for locals and
    watchers, registers, etc. In addition, Qt Creator includes features to make
    debugging Qt-based applications easy. The debugger frontend understands the
    internal layout of several Qt classes such as QString, the QTL containers,
    and most importantly QObject (and classes derived from it), as well as
    most containers of the C++ Standard Library. Therefore, the debugger can
    present their contents in a useful way.

        \row
            \o Debugging tools for Windows
            \o Using this engine requires you to install the

               \l{http://www.microsoft.com/whdc/devtools/debugging/installx86.Mspx}{32-bit}
               or
               \l{http://www.microsoft.com/whdc/devtools/debugging/install64bit.Mspx}{64-bit}
               package (Version 6.11.1.404 for the 32-bit or the 64-bit version of Qt Creator, respectively),
               which is freely available for download from the
               \l{http://msdn.microsoft.com/en-us/default.aspx}
               {Microsoft Developer Network}.

               The pre-built \e{Qt SDK for Windows} makes use
               of the library if it is present on the system. When building Qt
               Creator using the Microsoft Visual C++ Compiler, the
               \c{"%ProgramFiles%\Debugging Tools for Windows"} path is
               checked to ensure that all required header files are there.
    \endtable


    \section1 Interaction with the Debugger

    In \gui Debug mode, several dock widgets are used to interact with the
    program you are debugging. The frequently used dock widgets are visible by
    default; the rarely used ones are hidden. To change the default settings,
    select \gui Debug and then select \gui View.

    \image qtcreator-debug-view.png

    Here, you can lock or unlock the location of your views as well as display
    or hide them. Among the views you can display are \gui Breakpoints,
    \gui Stack, \gui Thread, \gui Modules, \gui Registers, \gui Disassembler,
    and \gui Debugger. The position of your dock widgets is saved for future
    sessions.


    \section2 Usage of the Debugger

    To start a program under the debugger's control, select the \gui{Debug}
    menu and \gui{Start Debugging}, or press \key{F5}. Qt Creator
    checks whether the compiled program is up-to-date, rebuilding it if
    necessary. The debugger then takes over and starts the program.

    \note Starting a program in the debugger can take a considerable amount of
    time, typically in the range of several seconds to minutes if complex
    features (like QtWebKit) are used.

    Once the program starts running, it behaves and performs as usual.
    The user can interrupt a running program by selecting
    \gui {Interrupt} from the \gui{Debug} menu. The program is automatically
    interrupted as soon as a breakpoint is hit.

    Once the program stops, Qt Creator:

    \list
        \o Retrieves data representing the call stack at the program's current
           position.
        \o Retrieves the contents of local variables.
        \o Examines \gui Watchers.
        \o Updates the \gui Registers, \gui Modules, and \gui Disassembler
           views.
    \endlist


    You can use the debugger views to examine the data in more detail.

    To finish debugging, press \key{Shift+F5}. A line of code can be executed
    as a whole with \key F10; to step into a function or a sub-function, use
    \key F11. Alternatively, you can continue running the program with \key F5.
    It is also possible to continue executing the program until the current
    function completes or jump to an arbitrary position in the current
    function.


    \section2 Breakpoints

    Breakpoints are shown in the \gui{Breakpoints} view which is enabled
    by default. This view is also accessible when the debugger and the program
    being debugged is not running.

    A breakpoint represents a position or sets of positions in the code that,
    when executed, interrupts the program being debugged and passes the
    control to the user. The user is then free to examine the state of the
    interrupted program, or continue execution either line-by-line or continuously.

    Typically, breakpoints are associated with a source code file and line, or
    the start of a function -- both are allowed in Qt Creator.

    Also, the interruption of a program by a breakpoint can be restricted with
    certain conditions.

    You can set a breakpoint:

    \list
       \o At a particular line you want the program to stop -- click on the
          left margin or press \key F9 (\key F8 for Mac OS X).
       \o At a function that you want the program to interrupt -- enter the
          function's name in \gui{Set Breakpoint at Function...} in
          \gui Debug menu.
    \endlist

    You can remove a breakpoint:

    \list
        \o By clicking on the breakpoint marker in the text editor.
        \o By selecting the breakpoint in the breakpoint view and pressing
           \key{Delete}.
        \o By selecting \gui{Delete Breakpoint} from the breakpoint's context
           menu in the \gui Breakpoints view.
    \endlist

    Breakpoints can be set and deleted before the program has actually started
    running or while it is running under the debugger's control. Also,
    breakpoints are saved together with a session.


    \section2 Stack

    When the program being debugged is interrupted, Qt Creator displays the
    nested function calls leading to the current position as a \e call stack
    trace. This stack trace is built up from \e{call stack frames}, each
    representing a particular function. For each function, Qt Creator tries
    to retrieve the file name and line number of the corresponding source
    file. This data is shown in the \gui Stack view.

    \image qtcreator-debug-stack.png

    Since the call stack leading to the current position may originate or go
    through code for which no debug information is available, not all stack
    frames have corresponding source locations. These frames are
    grayed out in the \gui Stack view.

    If you click on a frame with a known source location, the text editor
    jumps to the corresponding location and updates the \gui{Locals and Watchers}
    view, making it seem like the program was interrupted before entering the
    function.


    \section2 Threads

    If a multi-threaded program is interrupted, the \gui Thread view  or the
    combobox named \gui Thread in the debugger's status bar can be used to
    switch from one thread to another. The \gui Stack view adjusts itself
    accordingly.


    \section2 Modules View and Source Files View

    These views display the debugger's idea of the components of the
    application. By default, both views are hidden.


    \section2 Disassembler View and Registers View

    By default, both \gui Disassembler and \gui Registers view are hidden.
    The \gui Disassembler view displays disassembled code for the current
    function; the \gui Registers view displays the current state of the CPU's
    registers. Both views are useful for low-level commands such as
    \gui{Step Single Instruction} and \gui{Step Over Single Instruction}.

    \section2 Locals and Watchers

    Whenever a program stops under the control of the debugger, it retrieves
    information about the topmost stack frame and displays it in the
    \gui{Locals and Watchers} view. This typically includes information about
    parameters of the function in that frame as well as the local variables.

    Compound variables of struct or class type are displayed as
    "expandable" in the view. Click on the "+" to expand the entry and show
    all members. Together with the display of value and type, the user can
    examine and traverse the low-level layout of an object's data.


    \table
        \row
            \i  \bold{Note:}

        \row
            \i  Gdb, and therefore Qt Creator's debugger works for optimized
                builds on Linux and Mac OS X. However, optimization may lead
                to re-ordering of instructions or sometimes even complete
                removal of some local variables. In this case, the
                \gui{Locals and Watchers} view may show unexpected data.

        \row
            \i  The debug information provided by gcc does not include enough
                information about the time when a variable is initialized.
                Therefore, Qt Creator can not tell whether the contents of a
                local variable contains "real data", or "initial noise". If a
                QObject appears uninitialized, its value is reported as
                "out of scope". However, not all uninitialized objects can be
                recognized as such.
    \endtable


    The \gui{Locals and Watchers} view also provides access to the most
    powerful feature of the debugger: comprehensive display of data belonging
    to Qt's basic objects. To enable this feature, select \gui{Use
    debugging helper} from the \gui Debug menu.The
    \gui{Locals and Watchers} view is re-organized to provide a high-level
    view of the objects. For example, in case of QObject, instead of displaying
    a pointer to some private data structure, you see a list of children,
    signals and slots.

    Similarly, instead of displaying many pointers and integers, Qt Creator's
    debugger displays the contents of a QHash or QMap in an orderly manner.
    Also, the debugger displays access data for QFileInfo and provides
    access to the "real" contents of QVariant.

    The \gui{Locals and Watchers} view can be used to change the contents of
    variables of simple data types such as \c int or \c float when the program
    is interrupted. To do so, click on the \gui Value column, modify the value
    with the inplace editor, and hit \key Enter (or \key Return).

    \note The set of watched items is saved in your session.


    \section1 Debugging Helper Library

    While debugging, Qt Creator dynamically loads a helper library into your
    program. This helper library enables Qt Creator to pretty print Qt and STL
    types. The Qt SDK package already contains a prebuilt debugging helper
    library. To create an own debugging helper library, select \gui{Options}
    from the \gui{Tools} menu, and go to the \gui{Qt4 > Qt Versions} pane. As
    the internal data structures of Qt can change between versions, the debugging
    helper library is built for each Qt version.


    \section1 Walkthrough for the Debugger Frontend

    In our \l{Writing a Simple Program with Qt Creator}{TextFinder} example, we
    read a text file into QString and then display it with QTextEdit.
    Suppose you want to look at this QString, \c{line}, and see what
    data it actually stores. Follow the steps described below to place a
    breakpoint and view the QString object's data.

    \table
        \row
            \i \inlineimage qtcreator-setting-breakpoint1.png
            \i \bold{Setting a Breakpoint}

    \list 1
        \o Click in between the line number and the window border on the line
        where we invoke \l{http://doc.trolltech.com/qtextedit.html#plainText-prop}{setPlainText()}
        to set a breakpoint.
        \o Select \gui{Start Debugging} from the \gui{Debug} menu or press \key{F5}.
    \endlist

        \row
            \i \inlineimage qtcreator-setting-breakpoint2.png
            \i \bold{Viewing and removing breakpoints}

    Breakpoints are visible in the \gui{Breakpoints} view in
    \gui{Debug} mode. To remove a breakpoint, right-click on
    it and select \gui{Delete breakpoint} from the context menu.

        \row
            \i \inlineimage qtcreator-watcher.png
            \i \bold{Viewing Locals and Watchers}

    To view the contents of \c{line}, go to the \gui{Locals and
    Watchers} view.

    \endtable

    Suppose we modify our \c{on_findButton_clicked()} function to move back to
    the start of the document and continue searching once the cursor hits the
    end of the document. Adding this functionality can be done with the code
    snippet below:

    \code
    void TextFinder::on_findButton_clicked()
    {
        QString searchString = ui->lineEdit->text();

        QTextDocument *document = ui->textEdit->document();
        QTextCursor cursor = ui->textEdit->textCursor();
        cursor = document->find(searchString, cursor,
            QTextDocument::FindWholeWords);
        ui->textEdit->setTextCursor(cursor);

        bool found = cursor.isNull();

        if (!found && previouslyFound) {
            int ret = QMessageBox::question(this, tr("End of Document"),
            tr("I have reached the end of the document. Would you like "
            "me to start searching from the beginning of the document?"),
            QMessageBox::Yes | QMessageBox::No, QMessageBox::Yes);

            if (ret == QMessageBox::Yes) {
                cursor = document->find(searchString,
                    QTextDocument::FindWholeWords);
                ui->textEdit->setTextCursor(cursor);
            } else
                return;
        }
        previouslyFound = found;
    }
    \endcode

    However, if you compile and run this code, the application does not work
    correctly due to a logic error. To locate this logic error, step
    through the code using the following buttons:

    \title CMake Support in Qt Creator

    Since Qt Creator 1.1, support for \c CMake project files is available.
    Qt Creator 1.3 supports the Microsoft Toolchain if the CMake version
    is at least 2.8.

    \section1 Opening CMake Projects

    To open a \c CMake project, select \gui Open from the \gui File menu and
    select the \c{CMakeLists.txt} file from your \c CMake project. A wizard
    guides you with the rest of the process. If the \c CMake project does
    not have an in-place build, Qt Creator lets you specify the directory in
    which the project is built (\l{glossary-shadow-build}{shadow build}).

    \image qtcreator-cmake-import-wizard1.png

    The screenshot below shows how you can specify command line arguments to
    \c CMake for your project.

    \image qtcreator-cmake-import-wizard2.png

    Normally, there is no need to pass any command line arguments for projects
    that are already built, as \c CMake caches that information.


    \section1 Building CMake Projects

    Qt Creator builds \c CMake projects by running \c make, \c mingw32-make, or
    \c nmake depending on your platform. The build errors and warnings are
    parsed and displayed in the \gui{Build Issues} output pane.

    By default, Qt Creator builds the \e{all} target. You can specify which
    targets to build in \gui{Project} mode, under \gui{Build Settings}.

    \image qtcreator-cmake-build-settings.png

    Qt Creator supports multiple build configurations. Also, the build
    directory can be modified after the initial import.

    \section1 Running CMake Projects
    Qt Creator automatically adds \gui{Run Configurations} for all targets
    specified in the \c CMake project file.

    Known issues for the current version can be found
    \l{Known Issues of version 1.3.1}{here}.

    \nextpage creator-external-library-handling.html

    \title Support for Generic Projects in Qt Creator

    Since Qt Creator 1.1, generic projects are supported in addition to
    \c qmake projects. In other words, you can import existing projects that do
    not use \c qmake or \c CMake and Qt Creator ignores your build
    system.

    This feature lets you use Qt Creator as a code editor. You can change the
    way your project is built by modifying the \c make command under
    \gui{Build Settings} in the \gui{Projects} mode.

    For a generic project, you have to manually specify which files belong to
    your project and which include directories/defines you want to pass to your
    compiler.


    \section1 Specifying Files

    The list of files for a generic project is specified in the \c{.files}
    file. When you first create a generic project, Qt Creator adds any
    files it recognizes to your project. To add or remove files later,
    edit the \c{.files} file in Qt Creator. Your project tree is refreshed
    when you save this file. You can also add or remove files from the context
    menu in the project tree.

    If you frequently need to update the \c{.files} file, we recommend the use
    of a small script that updates the files for you. If the
    file is modified externally, Qt Creator must be restarted for the changes
    to take effect.


    \section1 Specifying Include Paths

    The include paths are specified in the \c{.includes} file, one include
    path per line. The paths can be either absolute or relative to the
    \c{.includes} file.

    \section1 Specifying Defines

    The defines are specified in the \c{.config} file. This file is a regular
    C++ file, prepended to all your source files when they are being parsed.
    However, you should only use it to add lines like the following:

    \code
    #define NAME value
    \endcode


    \section1 Creating a Run Configuration

    Qt Creator cannot automatically determine which executable it should run.
    To set up a custom executable run configuration in the \gui Projects mode,
    use the \bold{Add} button. Here you can specify the name, executable, and
    some optional arguments. By default, the working directory is
    \c{$BUILDDIR} which should work fine.

    \title Development of Qt for Symbian Based Applications

    Qt Creator 1.3 comes with preliminary support for development of
    applications using Qt for the Symbian Platform.

    \e{Note that this is highly experimental, and not intended for production use.
    The primary aim is to allow Symbian developers to familiarize themselves with Qt Creator
    and provide feedback that helps us improve Symbian support in future versions of
    Qt Creator.}

    Please provide us with feedback, using the mailing list or IRC, as described on the
    \l{http://qt.gitorious.org/qt-creator/pages/Home}{Qt Creator Development Wiki}.

    \section1 Getting Started with Symbian Based Applications

    You need the following software installed on your PC.
    Only Windows development is supported.

    \list
        \o \l{http://www.forum.nokia.com/main/resources/tools_and_sdks/S60SDK/}
            {S60 Platform SDK 3rd Edition FP1 or higher}
        \o \l{http://www.forum.nokia.com/main/resources/technologies/openc_cpp/}
            {Open C/C++ v1.6.0 or higher} (Install this to all S60 SDKs you plan to use Qt with.
            This is included in the Qt for Symbian binary installers.)
        \o Either the GCCE ARM Toolchain that is included in the S60 Platform SDKs, or
            RVCT 2.2 [build 686] or later (which is not available free of charge)
            (Your environment needs to find the compiler in the PATH.)
        \o Qt for Symbian 4.6.0, installed into the S60 SDKs you want to use

    \endlist

    For deploying and running applications on the device, you need the following:
    \list
        \o The Nokia USB drivers that come e.g. with PC Suite
        \o The \l{http://tools.ext.nokia.com/trk/}{App TRK} application for your device
    \endlist

    Running Qt based applications on real devices requires the following packages to be installed on
    your device. The packages can be found in the S60 SDK where you installed Open C/C++:
    \list
        \o nokia_plugin\\openc\\s60opencsis\\pips_s60_\<version\>.sis
        \o nokia_plugin\\openc\\s60opencsis\\openc_ssl_s60_\<version\>.sis
        \o nokia_plugin\\opencpp\\s60opencppsis\\stdcpp_s60_\<version\>.sis
    \endlist

    If you want to run your applications in the Symbian emulator, you also need to install
    Carbide.c++ v2.0.0 or higher.

    \section1 Setting Up Qt Creator

    When you run Qt Creator after installing the S60 Platform SDK and Qt for Symbian,
    the installed SDKs and their corresponding Qt versions are automatically detected.
    For each detected S60 SDK with Qt, a special entry is made in the Qt version management
    settings \gui{Tools > Options... > Qt4 > Qt Versions}.

    \e{Note that if you manually add a Qt version for Symbian, you must
    also manually specify the S60 SDK to use for this version.}

    \image qtcreator-qt4-qtversions-win-symbian.png

    If you want to run your applications in the Symbian emulator, you need to point Qt Creator
    to the Metrowerks Compiler that you want to use, by setting the \gui{Carbide Directory}
    of the Qt version to the corresponding Carbide.c++ installation directory.

    You can check what S60 SDKs and corresponding Qt versions are found in the
    \gui{Tools > Options... > Qt4 > S60 SDKs} preference page.

    \image qtcreator-qt4-s60sdks.png

    \section1 Building Your Project

    After installing all the prerequisites and checking the setup in Qt Creator as described
    above, you need to set up your project.
    \e{Note that the only supported build system for Qt for Symbian applications in Qt Creator
    is qmake.}

    Before you can build your project for the Symbian platform, you need to create build
    configurations for it.
    Open \gui{Projects mode} and make sure that your project is selected for editing in
    \gui{Edit Project Settings for Project ...}. Add debug and release build configurations
    for the Symbian target by selecting the corresponding Qt version from the build configuration
    \gui{Add} menu.

    \image qtcreator-symbian-add-buildconfiguration.png

    The created build configurations default to using the GCCE tool chain. If you want to build
    for the device using RVCT, or for the Symbian emulator using WINSCW, select \gui{Show Details}
    and change the tool chain in the \gui{General} section of the build configuration settings.

    Now you can switch to building your project for the device by selecting one of the
    new build configurations as the active configuration at the top of \gui{Projects mode}.

    \image qtcreator-symbian-change-buildconfiguration.png

    \section1 Running Your Project

    \section2 Running Your Project in the Emulator

    Similar to the build configuration setup for your project, you need to create a run
    configuration for running your project in the Symbian emulator:
    \list 1
        \o Switch to \gui{Projects mode}.
        \o Select \gui{Run Settings} > \gui{Add > YourApplication in Symbian Emulator}
    \endlist

    \image qtcreator-symbian-add-run-in-emulator.png

    To start your project in the emulator, select this run configuration as the active configuration
    at the top of \gui{Projects mode} window and press the run button.

    \image qtcreator-symbian-change-run-in-emulator.png

    \section2 Running Your Project on the Device

    To run your project on a real Symbian device, just add another run configuration in
    \gui{Projects mode} via \gui{Run Settings} > \gui{Add > YourApplication on Symbian Device}.

    \image qtcreator-symbian-add-runconfiguration.png

    \image qtcreator-symbian-details-runconfiguration.png

    In the details of the run configuration you can specify a certificate to use, and
    select one of the devices that you have currently attached to your computer.
    The only connection mode supported at the moment is USB in \e{PC Suite} mode.
    For actually running your application on the device, you need to set the device run configuration
    as the active configuration at the top of \gui{Projects mode}.
    Start the \gui{App TRK} application on your device and press the run button to create
    a package for your application, deploy, install and run it automatically on your device.

    \image qtcreator-symbian-change-runconfiguration.png

    \section2 Troubleshooting

    When something goes wrong, check the following:
    \list
        \o Did you build your application with a Qt version for Symbian?
        \o Are the settings for the Qt version you use to build your project correct? Check the
           path to the S60 SDK. Check also whether you need to specify the path to your compiler tool chain.
        \o Is the emulator/device run configuration selected as the active run configuration?
        \o Did you build using the right toolchain, i.e. WINSCW for running in the emulator,
            GCCE or RVCT for running on the device?
        \o If the emulator process could not be started, try closing Qt Creator and starting the
            application directly from your file manager. Having done this, Qt Creator should be
            able to run your projects in the emulator.
        \o Is the device connected via USB in \e{PC Suite} mode?
        \o Is App TRK running on the device, using the USB connection, and does it have status
            \e{connected}?
        \o Is your device detected and selected in the run configuration details?
    \endlist

    If neither of this helps to solve your problem, search the qt-creator@trolltech.com
    mailing list archives or provide feedback to us via the methods described on the
    \l{http://qt.gitorious.org/qt-creator/pages/Home}{Qt Creator Development Wiki}.

    \title External Libraries

    The ability to recognize external libraries is not only important for the
    underlying build system, but also for Qt Creator itself. This ability
    allows Qt Creator to support code completion and syntax highlighting for
    external libraries as if they were part of the current project or the Qt
    library.

    The procedure of adding a library to a project depends on the type of
    project, which influences the build system used. The following sections
    describe the procedure required for each project type.


    \section1 QMake Projects (the default)

    Open your project file (\c{.pro}) from the \gui{Projects} pane. Then,
    follow the guidelines in the
    \l{http://doc.trolltech.com/latest/make-project-files.html#declaring-other-libraries}
    {Declaring other Libraries} section of the Qt documentation.

    Syntax completion and highlighting work once your project successfully builds
    and links against the external library.


    \section1 CMake Projects

    In CMake, libraries are usually detected using the \c{FIND_PACKAGE()}
    macro. A couple of them are already being shipped with CMake, they can be
    found in the \c{Modules} directory of your CMake installation. If you
    provide libraries on your own, you need to provide your own
    \c{FindFoo.cmake} file. Refer to the
    \l{http://vtk.org/Wiki/CMake_FAQ#Writing_FindXXX.cmake_files}{CMake FAQ}
    for details.

    As with \c qmake projects, syntax completion and highlighting work
    once you successfully build and link against the external library.


    \section1 Generic Projects

    If you import a project using the \e{Generic Projects} function, Qt Creator
    creates a file called \c{<projectname>.includes} in your project root
    directory. This file contains all project subdirectories for which Qt Creator
    found relevant headers. Add your include paths here.

    Note that in \gui{Generic Project} mode, Qt Creator does not modify any project
    settings.

    \title Tips and Tricks

    \bold{Quickly Switching between Modes}

    You can quickly switch between modes by pressing \key{Ctrl+1},
    \key{Ctrl+2}, and so on.

    \bold{Keyboard Shortcuts}

    Qt Creator provides a lot of useful keyboard shortcuts. Some useful
    shortcuts are listed \l{Keyboard Shortcuts}{here}.

    \bold{Running Qt Creator from the command line}

    You can start Qt Creator from a command prompt with the name of an existing
    session or \c{.pro} file by giving the name as argument on the command
    line.

    \bold{Show and hide the sidebar}

    You can show and hide the the sidebar in \gui Edit and \gui Debug mode by
    clicking on the corresponding icon, or by pressing \key{Alt+0} (Mac OS X:
    \key{Cmd+0}).

    \bold{Display signals and slots}

    If you have an instance of a class that is derived from QObject, and you
    would like to find all other objects connected to one of your object's
    slots using Qt's signals and slots mechanism -- you can enable
    \gui{Use Custom Display for Qt Objects} feature under the \gui Debug menu.

    In the \gui{Locals and Watchers} view, expand the object's entry and open
    the slot in the \e slots subitem. The objects connected to this slot are
    shown as children of the slot. This method works with signals too.

    \bold{Display low level data}

    If special debugging of Qt objects fails due to data corruption within the
    debugged objects, you can switch the debugging helpers off in the
    \gui{Debugger > Debugging Helper} options dialog.
    This makes the low-level structures visible again.

                \target glossary-system-qt
            \o  This is the Qt
                version for the \c qmake command found in your \c PATH
                environment variable.
                This is likely to be the system's Qt version.

            \o  The version of Qt configured in \gui{Tools > Options... > Qt 4
                > Default Qt Version}. This is the Qt version used by your
                new projects. It defaults to the Qt in PATH.

        \row
            \o
                \raw HTML
                Project&nbsp;Qt

            \o  The version of Qt configured in \gui{Build&Run > Build
                Settings > Build Configurations}. This is the Qt version that
                is actually used by a particular project. It defaults to
                Default Qt.

        \row
            \o

                \endraw
                \target glossary-shadow-build
            \o  Shadow building means building a project in a separate
                directory, the \e{build directory}. The build directory is
                different from the source directory. One of the benefits of
                shadow building is that it keeps your source directory clean.
                Shadow building is the best practice if you need many build
                configurations for a single set of source.

    \title Known Issues

    There are some known issues with Qt Creator.
    The development team is aware of them, there is no need to report them as bugs.

    \section1 Known Issues of Version 1.3.1

    \list
        \o Debugging Helper does not work while performing On-Device Debugging.

        \o QML Preview (Run Project) only works if built against Qt with
           Declarative UI.

        \o Setting breakpoints in code that is compiled into the binary more
           than once does not work.

        \o On Linux and Windows, installing Qt with one user account and
        then using it with another requires other users to manually set
        the Qt version. On Windows, setting the MinGW location is
        required as well. The same applies to the location of GDB for Symbian.
        A workaround is to copy %APPDATA%/Nokia/qtcreator.ini (Windows) or
        $HOME/.config/Nokia/QtCreator.ini (Linux) from the directory
        of the user who installed Qt Creator to the other user.
        This issue does not exist on Mac OS X.
    \endlist

    \section1 Known Issues of Version 1.2.0 and 1.2.1

    \list
        \o Gdb on Windows may not work if the 'Embassy \reg Security Center' software
           by 'Wave \reg Systems' is installed and active (causing crashes in \c{vxvault.dll)}).

        \o Only simple data types (POD) work in the Watch Window of CDB.

        \o Qt Creator uses SQLite for storing some of its settings. SQLite is
           known to have problems with certain NFS servers (most notably the
           nfs-user-server 2.2beta), since they can lock up the application
           when it tries to lock the database. If your home directory is on an
           NFS share and you encounter this issue, one option would be to
           switch to the nfs-kernel-server, or create a symlink so that the
           settings are stored locally.
    \endlist

    \section1 Known Issues of Version 1.1.0

    \list
        \o Paths or file names containing spaces or special characters, e.g.,
           colons, dollar signs, hash marks etc. may cause problems. This
           is because some of the tools Qt Creator uses in the background have
           restrictions on the characters allowed in file and directory names.
           To be on the safe side, we recommend creating projects and project
           items with names consisting of plain characters, numbers,
           underscores, and hyphens.

        \o \c{.pro} files are reformatted if files have been added or removed.
           Whitespace is not preserved.

        \o There is no IDE support for adding files to include (\c .pri) files.

        \o There is no IDE support for adding/removing sub-projects. Project
           hierarchies (SUBDIRS template) have to be created manually.

        \o The file system sidebar does not update automatically. As a
           workaround, switch to another directory and then back.

        \o Loading KDE4 designer plugins breaks the style in KDE < 4.2.1
           due to a bug in KDE.

        \o The DEFINES and INCLUDES set in \c{.pro} files are not dealt with
           on a file-specific level. Because of this, handling of DEFINES has
           been disabled completely. Also the \c{.qmake.cache} is not being
           parsed. In general, the \c{.pro} file parser is incomplete and
           problems are still to be expected.

        \o Code completion for generated UI header files is updated only
           after a build.

        \o Code completion does not support typedefs for nested classes.

        \o There is a kernel bug essentially making debugging unreliable on
           2.6.24 kernels for i386 (which is, unfortunately, the default on
           Ubuntu 8.04). See
           \l{https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/230315/} for
           details. The only solution to this problem is to boot another
           kernel.

        \o Gdb may take long to load debugging symbols, especially from large
           libraries like \c libQtWebKit. Starting the debugging module can
           take up to several minutes without visible progress.

        \o Setting breakpoints in files that do not have unique absolute
           paths may fail. For example, remounting parts of a file system
           using the --bind mount option.

        \o There is no syntax highlighting for \c CMake project files.

        \o Project files included from \c{CMakeLists.txt} are not shown in the
           navigation tree.

        \o Using the Visual Studio Compiler with \c CMake is not supported.

        \o Creating new \c CMake projects with Qt Creator is not supported.

        \o Having more than one build directory for \c CMake is not supported.

        \o Changing the build directory for \c CMake after the initial import
           is disabled.
