That's more or less what I do. The problem is not getting the right graphics state for the widget, it is restoring the previous state when I go back to the IDL command line. If that doesn't happen, random plots tend to scrawl all over the widget instead of going to a normal graphics window. Obviously I could use WSET, TVLCT etc on the command line if necessary, or just remember to click on the widget if I happen to run the cursor over it, but that's clunky and shouldn't be necessary (and isn't, under linux).
