CEGUI::MouseButton GLWidget::convertQtToCEGUIMouseButton (Qt::MouseButton button)

These functions can be used in key and mouse event handlers to inject events to CEGUI::System: 

void GLWidget::keyPressEvent (QKeyEvent* event)
{
	bool processed = (event->text ().size () == 1) && CEGUI::System::getSingleton ().injectChar (event->text ().at (0).unicode ());
	if (!processed)
		processed = processed || CEGUI::System::getSingleton ().injectKeyDown (convertQtToCEGUIKey (event->key (), event->modifiers ()));
}
 
void GLWidget::mousePressEvent (QMouseEvent* event)
{
	CEGUI::System::getSingleton ().injectMouseButtonDown (convertQtToCEGUIMouseButton (event->button ()));
}
