Input within a DrawingArea Widget

Many applications do their own drawing within a widget based on input. To provide consistency within the desktop environment, XmIm functions are recommended because the style and geometry management needed for an input method is managed by the VendorShell widget class. The application need only worry about handling key events, focus, and communicating the current input location within the drawing area. Using these functions requires some basic knowledge of the underlying Xlib input method architecture, but a developer need only be concerned with the XmIm pieces of information.
