I want to prevent files of a particular type from getting displayed in 
the 'Recently Used' list.  AFAICT that would mean me needing to prevent 
them from getting added to 'recently-used.xbel'?

Here's the scenario...  our dialog can display two types of file - let's 
call them "typeA" and "typeB".  But our application can only understand 
files of typeB.  If the user selects a file of typeA, we defer to a 3rd 
party app which converts it to typeB.  The conversion never needs to get 
done more than once.  So there's no need for files of typeA to ever 
appear in the Recently Used list.

I guess what I'm asking is this....

Our app interacts with the file chooser dialog through an object of type 
Gtk::FileChooserButton (strictly speaking, that's a gtkmm object so 
maybe I'm posting on the wrong list anyway...)

But the RecentManager object isn't a member of Gtk::FileChooserButton.  
It's a member of one of the panes that gets displayed when the resulting 
FileChooser dialog gets displayed after pressing the button.

So what API calls do I need to eventually arrive at a pointer to the 
RecentManager object?  It's a long way down the chain with several 
objects in between.  From the Gtk::Filechooser button, I assume:-

      1)  I'd need to get a pointer to the FileChooser dialog.
      2)  I'd then (possibly) need to get a pointer to the relevant pane??
      3)  I'd then (possibly) need to get a pointer to the 'Recently 
Used' list object??
      4)  And ultimately I'd need to get a pointer to the 
Gtk::RecentManager object so I could add a "changed" handler

Does that make sense or am I over-thinking all this??
