The IDLgrWindow::OnMouseMotion procedure method handles notification from the window that a mouse-motion event has occurred.
Note: This method is only useful in conjunction with the Export Bridge. The method is only a stub and provides no functionality. In your subclass of IDLgrWindow, you should override this method to provide your own functionality. Your method will be automatically called by the Export Bridge. For more information, see "Exporting Drawable Objects"(Chapter 11, IDL Connectivity Bridges in the help/pdf directory of your IDL installation).
