This event handler, for event mouseEvent, can be reimplemented in a subclass to receive mouse move events for the scene.
The default implementation depends on the mouse grabber state. If there is a mouse grabber item, the event is sent to the mouse grabber. If there are any items that accept hover events at the current position, the event is translated into a hover event and accepted; otherwise it's ignored.

This event handler, for event mouseEvent, can be reimplemented in a subclass to receive mouse press events for the scene.
The default implementation depends on the state of the scene. If there is a mouse grabber item, then the event is sent to the mouse grabber. Otherwise, it is forwarded to the topmost item that accepts mouse events at the scene position from the event, and that item promptly becomes the mouse grabber item.
If there is no item at the given position on the scene, the selection area is reset, any focus item loses its input focus, and the event is then ignored.

This event handler, for event mouseEvent, can be reimplemented in a subclass to receive mouse release events for the scene.
The default implementation depends on the mouse grabber state. If there is no mouse grabber, the event is ignored. Otherwise, if there is a mouse grabber item, the event is sent to the mouse grabber. If this mouse release represents the last pressed button on the mouse, the mouse grabber item then loses the mouse grab.
