try this code.

Qt Code:

Switch view

QKeyEvent key(QEvent::KeyPress, Qt::Key_PageDown, Qt::NoModifier);	QApplication::sendEvent(widget_reciver, &key);
if (key.isAccepted()) {
    //everything is ok
} else {
     //something wrong
}

QKeyEvent key(QEvent::KeyPress, Qt::Key_PageDown, Qt::NoModifier);	QApplication::sendEvent(widget_reciver, &key);
if (key.isAccepted()) {
    //everything is ok
} else {
     //something wrong
}

To copy to clipboard, switch view to plain text mode

thanks
but in My app the widget_reciver is the FireFox or the openOffice or other app is not the Qt's QWidget.
I don't know how to do that .
