Select the appropriate mode in the \l{Selecting Modes}{mode selector} (1). Are you ready to build the application for particular hardware or (5) run (3) or debug (4) it on a device? Use the kit selector (2) to select the appropriate \l{glossary-buildandrun-kit}{kit}. The task bar (7) displays output from these actions. Are you looking for a particular project, file, class, or function? Start typing its name in the \l{Searching with the Locator}{locator} (6). To see where the above controls are in the user interface, select \uicontrol Help > \uicontrol {UI Tour}. The following sections describe some \QC controls in more detail: \list \li \l{Selecting Modes}{Mode selector} \li \l{Working with Sidebars}{Sidebars} \li \l{Browsing Project Contents}{Views} \li \l{Viewing Output}{Output} \endlist \else You can use the \l{Selecting Modes}{mode selector} to switch to the \l{Design Views}{Design mode} (1), where you will do most of your work and the \l{Using the Help Mode}{Help} (2) mode, where you can read the product documentation. The other modes are for more advanced use, and you are likely to need them less often. Below the mode selector, you can find shortcuts to some more advanced functions, such as running the application or finding problems in the QML code by debugging or profiling it. \endif \section1 What's New? For information about new features and bug fixes in each \QC release, select \uicontrol Help > \uicontrol {Change Log}. \section1 For \macos Users \QC uses standard names and locations for standard features, such as \e preferences. In this manual, the names and locations on Windows and Linux are usually used to keep the instructions short. Here are some places to check if you cannot find a function, dialog, or keyboard shortcut on \macos when following the instructions: \table \header \li For \li Look In \row \li \uicontrol Edit > \uicontrol Preferences \li \uicontrol {\QC} > \uicontrol Preferences \row \li \uicontrol Help > \uicontrol {About Plugins} \li \uicontrol {\QC} > \uicontrol {About Plugins} \row \li Keyboard shortcuts \li \uicontrol {\QC} > \uicontrol Preferences > \uicontrol Environment > \uicontrol Keyboard \endtable \if defined(qtdesignstudio) \section1 Customizing the Menu By default, top-level menu items \uicontrol Build, \uicontrol Debug, and \uicontrol Analyze are not visible. These menu items have options for advanced functionality. To toggle the visibility of these menu items: \list 1 \li Go to \uicontrol Edit > \uicontrol Preferences. \li On the \uicontrol Environment tab, select \uicontrol{Qt Design Studio Configuration}. \li Clear the checkbox for the items that you want to be visible. \endlist \image studio-menu-item-visibility.png You need to restart \QDS to apply changes made to these settings. \endif \section1 Switching UI Themes Themes enable you to change the appearance of the UI from dark to light, for example. To switch themes, select \uicontrol Edit > \uicontrol Preferences > \uicontrol Environment, and then select a theme in the \uicontrol Theme field. \image qtcreator-options-environment-interface.png "Interface preferences" \section1 Changing Languages \QC has several language versions. If the system language is one of the supported languages, \QC selects it automatically. To change the language, select \uicontrol Edit > \uicontrol Preferences > \uicontrol Environment and select a language in the \uicontrol Language field. Select \uicontrol {Restart Now} to restart \QC and have the change take effect. \section1 High DPI Scaling The operating systems that \QC supports implement high dots-per-inch (DPI) scaling at varying levels. Therefore, \QC handles high DPI scaling differently on different operating systems: \list \li On \macos, \QC forces high DPI scaling, which means that it allows Qt to use the system scaling factor as the \QC scaling factor. \li On Windows, if you do not set \l{High DPI} {scaling environment variables}, \QC instructs Qt to detect the scaling factor and use it as the \QC scaling factor. \li On Linux, \QC leaves it to the user to enable high DPI scaling because the process varies so much on different distributions and windowing systems that it cannot be reliably done automatically. \endlist To override the default approach and always enable high-DPI scaling, select \uicontrol Edit > \uicontrol Preferences > \uicontrol Environment > \uicontrol {Enable high DPI scaling}. The changes will take effect after you restart \QC. \section1 Navigating with Keyboard \QC caters not only to those users who like to use the mouse, but also to those who are more comfortable with the keyboard. A wide range of \l{keyboard-shortcuts}{keyboard} and \l{Searching with the Locator} {navigation} shortcuts are available to help you work faster. \if defined(qtcreator) \section1 Useful Features For a list of useful \QC features described in other parts of the documentation, see \l{How-tos}. \endif \section1 Viewing Images \QC opens image files in the image viewer. \image qtcreator-image-viewer.png "Image viewer" Use the toolbar buttons or \l{Keyboard Shortcuts}{keyboard shortcuts} to: \list \li \inlineimage icons/export.png - Export SVG images to pixmaps or copy an image as a data URL, which enables you to include it in web pages as if it were an external resource \li \inlineimage icons/original-size.png - Return images to their original size \li \inlineimage icons/zoom-in.png - Zoom in and out (\inlineimage icons/zoom-out.png ) \li \inlineimage icons/run_small.png - Play and pause animated GIF and MNG images \li \inlineimage icons/qtcreator-desktopdevice-button.png - Show and hide the image background \li \inlineimage icons/switch-outline.png - Show and hide the image outline \li \inlineimage icons/fittoview.png - Fit images to screen \endlist Select \uicontrol {Set as Default} to use the current settings for the background and outline modes and fitting images to screen as default values for the image viewer. \section2 Exporting SVG Images If you have a freely scalable icon in the SVG format, you can export it to several images of different sizes to create a set of pixmaps. \if defined(qtcreator) You can then use QIcon::addPixmap() to add the pixmaps to icons in different modes and states. \endif \if defined(qtcreator) \section1 Location of Settings Files \QC creates the following files and directories: \list \li QtCreator.db \li QtCreator.ini \li qtversion.xml \li toolChains.xml \li qtcreator \li qtc-qmldump \endlist The location of the above files and directories depends on the platform: \list \li On Linux and other Unix platforms, look in \c {~/.config/QtProject} and \c {~/.local/share/data/QtProject/qtcreator}. \li On \macos, look in \c {~/.config/QtProject} and \c {~/Library/Application Support/QtProject/Qt Creator}. \li On Windows, look in \c {%appdata%\QtProject} and \c {%localappdata%\QtProject}. \endlist \endif */ /*! \page creator-modes.html \previouspage creator-quick-tour.html \if defined(qtdesignstudio) \nextpage creator-using-qt-quick-designer.html \else \nextpage creator-sidebars.html \endif \title Selecting Modes \image qtcreator-mode-selector.png \if defined(qtcreator) The mode selector allows you to quickly switch between tasks such as editing project and source files, designing application UIs, configuring projects for building and running, and debugging your applications.
