Are there dozy questions!? Well, if there are, I suppose
I specialize in answering them. They are my favorite kind. :-)

All you are going to be able to get from within IDL is
the contents of a graphics or draw widget window. Usually
(thank Goodness!) this is what you want in your GIF file.

When it is not (for example, when you want to see the
whole graphical user interface of a program), you will
have to get some kind of screen capture tool. On my
PC I like HyperSnap, which is a $25 program that you
can find out more about here:

There are many shareware or free tools that do a similar
job. I like HyperShap because you can include pull-down
menus and the cursor in captured images. This makes it
nice for illustrating how widget programs work in HTML
documentation.

Cheers,

David
