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 centered on the screen. It may be useful to add - the \c WStyle_StaysOnTop if you desire to keep above all the windows in the - GUI. - - 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. - - \code - int main( int argc, char **argv ) - { - TQApplication app( argc, argv ); - TQPixmap pixmap( "splash.png" ); - TQSplashScreen *splash = new TQSplashScreen( pixmap ); - splash->show(); - TQMainWindow *mainWin = new TQMainWindow; - ... - app.setMainWidget( mainWin ); - mainWin->show(); - splash->finish( mainWin ); - delete splash; - return app.exec(); - } - \endcode - - It is sometimes useful to update the splash screen with messages, - for example, announcing connections established or modules loaded - as the application starts up. TQSplashScreen supports this with the - message() 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 TQSplashScreen and reimplement - drawContents(). - - 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 TQApplication::processEvents() to receive the mouse clicks. - - \code - TQPixmap pixmap( "splash.png" ); - TQSplashScreen *splash = new TQSplashScreen( pixmap ); - splash->show(); - ... // Loading some items - splash->message( "Loaded modules" ); - tqApp->processEvents(); - ... // Establishing connections - splash->message( "Established connections" ); - tqApp->processEvents(); - \endcode - -*/ - -/*! - Construct a splash screen that will display the \a pixmap. - - There should be no need to set the widget flags, \a f, except - perhaps \c WDestructiveClose or \c WStyle_StaysOnTop. -*/ -TQSplashScreen::TQSplashScreen( const TQPixmap &pixmap, WFlags f ) - : TQWidget( 0, 0, (WFlags)(WStyle_Customize | TQt::WStyle_Splash | f) ) -{ - d = new TQSplashScreenPrivate(); - d->pixmap = pixmap; - setPixmap( d->pixmap ); // Does an implicit tqrepaint -} - -/*! - Destructor. -*/ -TQSplashScreen::~TQSplashScreen() -{ - delete d; -} - -/*! - \reimp -*/ -void TQSplashScreen::mousePressEvent( TQMouseEvent * ) -{ - hide(); -} - -/*! - This overrides TQWidget::tqrepaint().
