The graphics window index number (the window number
you want to WSET to) is the *value* of the draw widget.
If you know the ID of the draw widget (perhaps you clicked
somewhere in the window, so the ID is in the event structure)
you can easily get the window index number:
Widget_Control, event.ID, Get_Value=wid
WSet, wid
If you want to do something in other windows, you
have to know either the draw widget ID of those other
windows, or the window index number of the other windows
in order to draw into them.
Cheers,
David
