    \class Core::ICore
    \brief The ICore class allows access to the different parts that make up
    the basic functionality of \QC.

    You should never create a subclass of this interface. The one and only
    instance is created by the Core plugin. You can access this instance
    from your plugin through \c{Core::instance()}.

    \brief Opens a dialog where the user can choose from a set of \a wizards that
    create new files/classes/projects.

    The \a title argument is shown as the dialogs title. The path where the
    files will be created (if the user doesn't change it) is set
    in \a defaultLocation. It defaults to the path of the file manager's
    current file.

    Should be used to display configuration errors and point users to the setting.
    Returns true if the settings dialog was accepted.

    Use the progress manager to register a concurrent task to
    show a progress bar the way Qt Creator does it.
*/

/*!
    \fn VcsManager *ICore::vcsManager()
    \brief Returns the application's vcs manager.

    The vcs manager can be used to e.g. retrieve information about
    the version control system used for a directory on hard disk.
    The actual functionality for a specific version control system
    must be implemented in a IVersionControl object and registered in
    the plugin manager's object pool.
*/

/*!
    \fn QSettings *ICore::settings(QSettings::Scope scope = QSettings::UserScope)
    \brief Returns the application's main settings object.

    You can use it to retrieve or set application wide settings
    (in contrast to session or project specific settings).

    If \a scope is QSettings::UserScope (the default), the
    users settings will be read from the users settings, with
    a fallback to global settings provided with Qt Creator.

    If \a scope is QSettings::SystemScope, only the system settings
    shipped with the current version of Qt Creator will be read. This
    functionality exists for internal purposes only.

    \see settingsDatabase()
*/

/*!
    \fn SettingsDatabase *ICore::settingsDatabase()
    \brief Returns the application's settings database.

    The settings database is meant as an alternative to the regular settings
    object. It is more suitable for storing large amounts of data. The settings
    are application wide.

    \see SettingsDatabase
*/

/*!
    \fn QPrinter *ICore::printer()
    \brief Returns the application's printer object.

    Always use this printer object for printing, so the different parts of the
    application re-use its settings.
*/

/*!
    \fn QString ICore::resourcePath()
    \brief Returns the absolute path that is used for resources like
    project templates and the debugger macros.

    This abstraction is needed to avoid platform-specific code all over
    the place, since e.g. on Mac the resources are part of the application bundle.
*/


/*!
    \fn QString ICore::userResourcePath()
    \brief Returns the absolute path in the users directory that is used for
    resources like project templates.

    Use this method for finding the place for resources that the user may
    write to, e.g. to allow for custom palettes or templates.
*/

/*!
    \fn QWidget *ICore::mainWindow()
    \brief Returns the main application window.

    For use as dialog parent etc.
*/

/*!
    \fn IContext *ICore::currentContextObject()
    \brief Returns the context object of the current main context.

    \brief Change the currently active additional contexts.

    Removes the list of additional contexts specified by \a remove and adds the
    list of additional contexts specified by \a add.

    \sa ICore::hasContext()
*/

/*!
    \fn bool ICore::hasContext(int context) const
    \brief Returns if the given \a context is currently one of the active contexts.

    \sa ICore::updateAdditionalContexts()
    \sa ICore::addContextObject()
*/

/*!
    \fn void ICore::addContextObject(IContext *context)
    \brief Registers an additional \a context object.

    After registration this context object gets automatically the
    current context object whenever its widget gets focus.

    \sa ICore::removeContextObject()
    \sa ICore::updateAdditionalContexts()

    \brief Emitted to signal that the user has requested that the global settings
    should be saved to disk.

    At the moment that happens when the application is closed, and on \gui{Save All}.
*/

/*!

    \brief Signal that allows plugins to perform actions just before the \gui{Tools|Options}
    dialog is shown.
*/

/*!
    \fn void ICore::coreAboutToClose()
    \brief Plugins can do some pre-end-of-life actions when they get this signal.

    The application is guaranteed to shut down after this signal is emitted.
    It's there as an addition to the usual plugin lifecycle methods, namely
    IPlugin::aboutToShutdown(), just for convenience.
