setGeometry()

void QUIKitWindow::setGeometry ( const QRect &  rect )

virtual

This function is called by Qt whenever a window is moved or the window is resized.

The resize can happen programatically(from ie. user application) or by the window manager. This means that there is no need to call this function specifically from the window manager callback, instead call QWindowSystemInterface::handleGeometryChange(QWidget *w, const QRect &newRect);

Reimplemented from QPlatformWindow.

Definition at line 355 of file quikitwindow.mm.

{
    // Not supported. Only a single "full screen" window is supported
    QPlatformWindow::setGeometry(rect);
}
