David,
Thanks very much. While I can see that cgPickfile offers some useful
options not present in dialog_pickfile, I'm not sure if it's quite
suitable for my purpose. The idea here is the the files have already
been selected, and the selected files are displayed in a list of some
kind, such that the user can highlight any given one of those files in
order to tweak the processing steps for that file (with options given
in the widget application). As such, I think it's quite important that
the list would be embedded directly into the top-level base of the
application. The files themselves might not all be in the same
directory.
Another slightly less satisfactory route I was considering exploring
would be to use widget_list, but truncate the displayed paths so that
the rightmost portion of the path is visible. However, this requires a
way to calculate how much of the string will exactly fit in the
available space. I suppose I could set the list to be a set width in
characters, and then at least be sure that if I truncate each string
to be equal to that width, they would fit in the box. I think it'd be
quite unattractive though.
