For an - application, one of the available screens is the primary screen, i.e. - the screen where the main widget resides (see primaryScreen()). All - windows opened in the context of the application should be - constrained to the boundaries of the primary screen; for example, - it would be inconvenient if a dialog box popped up on a different - screen, or split over two screens. - - The QDesktopWidget provides information about the geometry of the - available screens with screenGeometry(). The number of screens - available is returned by numScreens(). The screen number that a - particular point or widget is located in is returned by - screenNumber(). - - Widgets provided by Qt use this class, for example, to place - tooltips, menus and dialog boxes according to the parent or - application widget. - - Applications can use this class to save window positions, or to place - child widgets on one screen. - - \img qdesktopwidget.png Managing Multiple Screens - - In the illustration above, Application One's primary screen is - screen 0, and App Two's primary screen is screen 1. - - \target multiple screens note - \note QDesktopWidget inherits the QWidget properties, width() and - height(), which specify the size of the desktop. However, for - desktops with multiple screens, the size of the desktop is the union - of all the screen sizes, so width() and height() should \e not be - used for computing the size of a widget to be placed on one of the - screens. The correct width and height values are obtained using - availableGeometry() or screenGeometry() for a particular screen. - - \sa QApplication, QApplication::desktop(), QX11Info::appRootWindow() -*/ - -/*! - \fn QDesktopWidget::QDesktopWidget() - - \internal - - Creates the desktop widget. - - If the system supports a virtual desktop, this widget will have - the size of the virtual desktop; otherwise this widget will have - the size of the primary screen. - - Instead of using QDesktopWidget directly, use QApplication::desktop(). -*/ - -/*! - \fn QDesktopWidget::~QDesktopWidget() - - \internal - - Destroys the desktop widget and frees any allocated resources. -*/ - -/*! - \fn bool QDesktopWidget::isVirtualDesktop() const - - Returns true if the system manages the available screens in a - virtual desktop; otherwise returns false. - - For virtual desktops, screen() will always return the same widget. - The size of the virtual desktop is the size of this desktop - widget. -*/ - -/*! - \fn int QDesktopWidget::primaryScreen() const - - Returns the index of the primary screen. - - \sa numScreens() -*/ - -/*! - \fn int QDesktopWidget::numScreens() const - - Returns the number of available screens. - - \sa primaryScreen() -*/ - -/*! - \fn QWidget *QDesktopWidget::screen(int screen) - - Returns a widget that represents the screen with index \a screen - (a value of -1 means the default screen). - - - If the system uses a virtual desktop, the returned widget will - have the geometry of the entire virtual desktop; i.e., bounding - every \a screen. - - \sa primaryScreen(), numScreens(), isVirtualDesktop() -*/ - -/*! - \fn const QRect QDesktopWidget::availableGeometry(int screen) const - - Returns the available geometry of the screen with index \a screen.
