Remarks

This method is called by the built-in tools to capture the mouse during a user interaction, so that mouse event continue to be sent to the control even if the mouse cursor moves outside the control window.

The MapControl (C++ base class) provides a default implementation on Windows that will capture 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 capture the mouse instead.

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