I honestly don't really understand what are you trying to achieve. do
you want to add files, or is it just an issue of displayed files?

the file chooser widget will add the currently selected file to the
list of recently used files automatically. an argument could be made
for having this behind as a setting, but playing games with the
GtkRecentManager API does not really strike me as a viable, long term
solution. after all, anything can add that file to the list of
recently used files.

the file chooser widget should also use the currently selected filter
when displaying the recently used files, so if you want to display a
certain file type or extension, you should use the facilities offered
by the file chooser API.

a GtkRecentManager is a GObject; you just connect to the changed
signal, like you would on any other GObject instance.

ciao,
