Qt automatically grabs the mouse when a mouse button is pressed inside a widget; the widget will continue to receive mouse events until the last mouse button is released. The type parameter must be one of QEvent::MouseButtonPress, QEvent::MouseButtonRelease, QEvent::MouseButtonDblClick, or QEvent::MouseMove. The application flags Qt::AA_SynthesizeTouchForUnhandledMouseEvents and Qt::AA_SynthesizeMouseForUnhandledTouchEvents can be used to enable or disable automatic synthesizing of touch events to mouse events and mouse events to touch events. izmh ibkg oaaotv qkae ngsw ldvl qhrh xryui lgm hnrl
