User Interface Programming

Using Draw Widgets

Draw widgets are graphics windows that appear as part of a widget hierarchy rather than appearing as an independent window. Like other graphics windows, draw widgets can be created to use either Direct or Object graphics. (See Graphic Display Essentials for a discussion of IDL's two graphics modes.) Draw widgets allow designers of IDL graphical user interfaces to take advantage of the full power of IDL graphics in their displays. See WIDGET_DRAW for a complete description of the function used to create draw widgets.
