Remarks

This method will be called by the built-in tools to release a mouse capture, typically when the user releases a mouse button.

The MapControl (C++ base class) provides a default implementation on Windows that will release the mouse using Win32 calls. If you inherit directly from this a class you may wish to override this method to use functions of your GUI framework to release the mouse instead.

If you override this method, you should also override setCapture accordingly.
