Constructor & Destructor Documentation

QRootWindow()

		const char *	name = nullptr,
		bool	designermode = false )

Member Function Documentation

AddSubFrame()

void QRootWindow::AddSubFrame	(	TGFrame *	f,
		TGLayoutHints *	l = nullptr )

Add root subframe into this widget.

Definition at line 90 of file QRootWindow.cpp.

References fxRootwindow, and l.

closeEvent()

void QRootWindow::closeEvent ( QCloseEvent * e )

overrideprotected

Definition at line 224 of file QRootWindow.cpp.

eventFilter()

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

overrideprotected

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!
