I was thinking about this just the other day. When you get it built,
I'm sure others will be interested in it. :-)

CW_FILESEL is, uh, an "interesting" widget. But not what
I want, either. :-(

For those who are interested, I wrote a file selection utility that
uses tree widgets that does what I specified in my original posting.
In particular it allows you to specify a file type filter with an input
keyword and, if the user changes the filter while the dialog is
displayed, an output keyword will return the updated filter.
You can find the source code, RMD_PICKFILE.PRO, as well as a screen
shot on the following web page under the heading "Miscellaneous
programs":

Many thanks to David Fanning for providing valuable feedback on the
...ahem...er... aesthetic qualities of my original dialog that *didn't*
use a tree widget :).
Best,
Rob
