WaitMouseUp

After receiving a mouse-down event, you can use the WaitMouseUp function to determine if the user subsequently released the mouse.

FUNCTION WaitMouseUp: Boolean;

DESCRIPTION

The WaitMouseUp function looks in the Operating System event queue for a mouse-up event. If it finds one, the WaitMouseUp function removes the mouse-up event from the queue and returns TRUE. If it does not find any mouse events pending in the Operating System event queue, the WaitMouseUp function returns FALSE.
