Description
Is an OnMouseUp event dispatcher.
Override the protected MouseUp method to provide other responses in addition to calling the OnMouseUp event handler when the user releases a previously pressed mouse button while the cursor's hot spot is over the control.
A control calls MouseUp in response to any of the Windows mouse-up messages (WM_LBUTTONUP, WM_MBUTTONUP, WM_RBUTTONUP), decoding the message parameters into the shift-key state and position, which it passes in the Shift
, X
, and Y
parameters, respectively. The value of the Button
parameter indicates which mouse button was released: left, right, or middle.
