FileChooserDialog sort order

[Ludwig Hähne <wkx gmx li>]

Hello,

In the Gtkmm application I'm working on the user always has to switch
the sort order of the file chooser dialog to account for the file naming
scheme employed here. Therefore I searched for ways to alter the sort
order of the FileChooserDialog so that it sorts the files displayed by
date instead of by name. However, I could not find a function in the
class reference that would provide that functionality.

A different approach was to add the FileChooserDialog as a member to my
main window so that it doesn't get destroyed, hoping that upon reopening
the state would be kept during a program session. This keeps the folder
selected but not the sort order which resorts to sort-by-name.

I'm running out of ideas, so a little help in answering one of the
questions would be very appreciated:

Is this functionality (change sort-order) available at all in Gtkmm?

If not, is there maybe a hack to achieve the same under Linux/Gnome?

Is it "good practice" to keep a dialog as a member to preserve its state?

Thanks, Ludwig
