void QRootWindow::AddSubFrame	(	TGFrame *	f,

bool QRootWindow::eventFilter ( QObject *  o, QEvent *  e  )

protectedvirtual

Event filter is used to pass Qt mouse events root, after translating them in MapQMouseEvent. Note that root grabs gui buttons via x11 directly, thus this mechanism is not used for the regular root widgets!
