Hi All,
I have just installed 5.5 and came across an error I hadn't seen in
5.4.
I use a 'PRO_SET_VALUE' routine to create a button each time I load an
image file. This button's UVALUE carries information about the file
and serves as a launching button for the file it represents. At the
end of the routine I use WIDGET_CONTROL to send an event to the just
created button to make it the 'currently' active button and update
some display labels. Unfortunately IDL comes back with the following
message:
% WIDGET_CONTROL: Request not allowed on unrealized widget.
This seems strange as the button must be realized, albeit implicitly,
since it appears on screen!
Any ideas how I might prevent the error?
Cheers!
