I would suggest using a scrollable list widget. You can easily use
the event structure to determine which item is selected. You can
also implement double-clicking.
If you want to see an example of this, you can look at my LHELP
program that allows the user to view all the *.doc (and *.pro)
files within IDL's !PATH:
ftp://bial8.ucsd.edu pub/software/idl/share
It will show you how to create and fill the list widget, and how
to process the events.
