Splash screens are often used for - applications that have long start up times (e.g. database or - networking applications that take time to establish connections) to - provide the user with feedback that the application is loading. - - The splash screen appears in the center of the screen. It may be - useful to add the Qt::WindowStaysOnTopHint to the splash widget's - window flags if you want to keep it above all the other windows on - the desktop. - - Some X11 window managers do not support the "stays on top" flag. A - solution is to set up a timer that periodically calls raise() on - the splash screen to simulate the "stays on top" effect. - - The most common usage is to show a splash screen before the main - widget is displayed on the screen. This is illustrated in the - following code snippet in which a splash screen is displayed and - some initialization tasks are performed before the application's - main window is shown: - - \snippet doc/src/snippets/qsplashscreen/main.cpp 0 - \dots - \snippet doc/src/snippets/qsplashscreen/main.cpp 1 - - The user can hide the splash screen by clicking on it with the - mouse. Since the splash screen is typically displayed before the - event loop has started running, it is necessary to periodically - call QApplication::processEvents() to receive the mouse clicks. - - It is sometimes useful to update the splash screen with messages, - for example, announcing connections established or modules loaded - as the application starts up: - - \snippet doc/src/snippets/code/src_gui_widgets_qsplashscreen.cpp 0 - - QSplashScreen supports this with the showMessage() function. If you - wish to do your own drawing you can get a pointer to the pixmap - used in the splash screen with pixmap(). Alternatively, you can - subclass QSplashScreen and reimplement drawContents(). -*/ - -/*! - Construct a splash screen that will display the \a pixmap. - - There should be no need to set the widget flags, \a f, except - perhaps Qt::WindowStaysOnTopHint. -*/ -QSplashScreen::QSplashScreen(const QPixmap &pixmap, Qt::WindowFlags f) - : QWidget(*(new QSplashScreenPrivate()), 0, Qt::SplashScreen | Qt::FramelessWindowHint | f) -{ - setPixmap(pixmap); // Does an implicit repaint -} - -/*! - \overload - - This function allows you to specify a parent for your splashscreen.
