Hello:
How will you rate the GUI Programming in IDL compared to VB and
others? I am really finding it tough to get along w/ it.
Everytime i change the prc file and regenerate the .pro file, the
event_cb file does not get updated. I have to then do save as and cut
paste all the event definitions. What is the way out??
Please reply

Thanks
Pravesh

I use the GUI-driven application code detailed in Liam Gumley's book, imgui I believe, as
a shell for all my widget apps (see http://www.gumley.com -- all the example code in the
book is available there in a tarball/zipfile). I used the IDL GUI Builder once or twice
and never used it again - I find a pencil and paper much more useful in designing IDL
widget GUI apps.

I run IDL on a Linux machine where the GUI builder is not available - so
I have learnt to code GUI by hand and when I used a windows machine and
tried the GUI builder I realised that coding by hand was much better. I
second the other opinions in this thread which recommend not using the
GUI builder.

Well, Tian, you aren't going to like this probably,
but the sizing you are doing in Windows is *exactly*
what is screwing everything up in Linux. :-)

Make you bases row and column bases, and use LOTS
of them to lay out your widgets. Forget *everything*
you know about sizing widgets (except for draw widgets,
maybe), and you *maybe* will have a chance at machine
portable code.

Cheers,

David

P.S. A good book is always a good idea. :-)

Once I changed the .prc file and re-generated the sources, I need to
double click the files in the project window to refresh their content.
IDL always prompted me to confirm the changes.

As to the IDLDE's GUIBuilder, I prefer using it in Windows. Because
the positioning of widgets is a big problem for me when munally write
the code. I am wondering which type of layout that others are using
for the top-level-base widget is. Can anybody can give me a clue on
GUI programming effectively?

Another old issue, are there any tricks to make GUI work fine in both
Windows and Linux?

Thanks.

Sincerely,
Tian
