really dumb widget question
When IDL is stopped within a procedure, a non-blocking widget will
still listen to events. But it won't act on them. Why not? Is there
any way to make it act on them?
E.g., if you run from the main level a procedure with a stop
statement, call XLOADCT, and hit one of the color table choices, the
color table will change to what you requested, but not until you
return to the main level. Calling LOADCT of course gets you a changed
color table right away.
I guess my problem is understanding how the widget event loop interacts
with the command line. Widgetheads, please help.
