>Note that if the event mask of an X window has selected both button press
 and button release events, then a button press event will cause an automatic
 pointer grab until the button is released. X does this automatically since
 most applications expect to receive button press and release events in
 pairs. It is equivalent to a pointer grab on the window with <TT
>owner_events</TT
>
 set to <TT
>True</TT
>.
</P
><P
>If you set up anything at the time you take the grab that needs to be
 cleaned up when the grab ends, you should handle the GdkEventGrabBroken
 events that are emitted when the grab ends unvoluntarily.
