Hi All,
I stumbled on a very useful feature (that IDL tech support said should
be a bug). Here's the situation:
I have IDL procedures that make calls to widget procedures
(e.g., PICKFILE) that are used to choose data files, do a little
processing, and then some plotting. Pretty average stuff.
I need Postscript output files for my presentations since
they provide the best resolution plots.
So, I usually set the device to 'PS', then run my IDL procedure.
Here's the feature/bug:
If I have already run the widget-using program at least once, then
set device to 'PS', everything works fine.
If I start up IDL, then set device to 'PS', then run my
widget-using program, I'll get this error:
"WIDGET_CONTROL: Routine is not defined for current graphics device."
So, all I have to do is to remember to run the procedure once, *then*
set the 'PS' device, then re-run the procedure. This means that
I don't have to write different procedures for X and Postscript
output. This is great! Unfortunately, when I mentioned this to
IDL tech support, the guy didn't seem to get it (maybe he thought
I was being sarcastic) and said that he'd make a bug report.
Hopefully,
this won't be "fixed" in 5.0. ASIDE: This even works for procedures
that make plots in more than one window --> more than one PS page.
Maybe no one else cares about this or maybe everyone else already knew,
but
I find it very convenient.
