Dear Paul and Craig,
Actually that *is* the behavior that I intended even though it may not
be obvious why. Each time I launched the dialog I did not want to load
in the contents of the entire directory hierarchy (in the interest of
speed). I only wanted to display the contents of the current directory
(subdirectories + files). Each time you double click on a subdirectory
then you go into it and the tree widget contents are updated to show
that directory's files and subdirectories. The "root" folder behaves
slightly differently in that if you double-click on it, you go up one
directory. Note that the +/- only expands or compresses the view of
the contents of the current directory. I probably could have done this
so that it was more intuitive (I'm certainly open to ideas :) )
Thanks for the feedback.
Rob
P.S. Craig, sorry for the gratuitous use of IDL 6 syntax.
