Member Function Documentation

QSplashScreen::QSplashScreen ( const QPixmap & pixmap = QPixmap(), Qt::WindowFlags f = 0 )

Construct a splash screen that will display the pixmap.

There should be no need to set the widget flags, f, except perhaps Qt::WindowStaysOnTopHint.

QSplashScreen::QSplashScreen ( QWidget * parent, const QPixmap & pixmap = QPixmap(), Qt::WindowFlags f = 0 )

This is an overloaded function.

This function allows you to specify a parent for your splashscreen. The typical use for this constructor is if you have a multiple screens and prefer to have the splash screen on a different screen than your primary one. In that case pass the proper desktop() as the parent.

QSplashScreen::~QSplashScreen () [virtual]

Destructor.

void QSplashScreen::clearMessage () [slot]

Removes the message being displayed on the splash screen

See also showMessage().

void QSplashScreen::drawContents ( QPainter * painter ) [virtual protected]

Draw the contents of the splash screen using painter painter. The default implementation draws the message passed by showMessage(). Reimplement this function if you want to do your own drawing on the splash screen.

bool QSplashScreen::event ( QEvent * e ) [virtual protected]

Reimplemented from QObject::event().

void QSplashScreen::finish ( QWidget * mainWin )

Makes the splash screen wait until the widget mainWin is displayed before calling close() on itself.

void QSplashScreen::messageChanged ( const QString & message ) [signal]

This signal is emitted when the message on the splash screen changes. message is the new message and is a null-string when the message has been removed.

See also showMessage() and clearMessage().

void QSplashScreen::mousePressEvent ( QMouseEvent * ) [virtual protected]

Reimplemented from QWidget::mousePressEvent().

const QPixmap QSplashScreen::pixmap () const

Returns the pixmap that is used in the splash screen. The image does not have any of the text drawn by showMessage() calls.

See also setPixmap().

void QSplashScreen::repaint ()

This overrides QWidget::repaint(). It differs from the standard repaint function in that it also calls QApplication::flush() to ensure the updates are displayed, even when there is no event loop present.

void QSplashScreen::setPixmap ( const QPixmap & pixmap )

Sets the pixmap that will be used as the splash screen's image to pixmap.

See also pixmap().

void QSplashScreen::showMessage ( const QString & message, int alignment = Qt::AlignLeft, const QColor & color = Qt::black ) [slot]

Draws the message text onto the splash screen with color color and aligns the text according to the flags in alignment.

See also Qt::Alignment and clearMessage().
