disable FileChooser elements?

[Doug Vetter <doug packetstorm com>]

Hi all.

I'm new to GTK and the list, so please bear with me.

Our application currently uses FileSelection with several of its widgets 
disabled / hidden.  For example, we disable folder selection because we 
restrict all data to a specific directory, and don't want the user 
open/saving in a different location.

With FileSelection it was relatively easy to disable various elements 
contained in the dialog we didn't want, a la:

fsel = gtk_file_selection_new(...yadda yadda...);
gtk_file_selection_hide_fileop_buttons(GTK_FILE_SELECTION(fsel));
gtk_widget_hide(GTK_FILE_SELECTION(fsel)->history_pulldown );
gtk_widget_hide(GTK_FILE_SELECTION(fsel)->selection_entry );
gtk_widget_hide(GTK_FILE_SELECTION(fsel)->selection_text );

I'd like to migrate to a FileChooserDialog (or FileChooserWidget) but I 
can't seem to figure out how to gain access to the necessary pointers 
(as defined in gtkfilechooserdefault.c) to accomplish the same thing:

 GtkWidget *browse_shortcuts_tree_view;
 GtkWidget *browse_shortcuts_add_button;
 GtkWidget *browse_shortcuts_remove_button;

Thoughts?
