GTK+ noob question here:
Would it be possible to customize the GtkFileChooserButton or GtkFileChooserDialog to remove the ‘Places’ section (on the left) and the ‘Location’ entry box on the top?
What I’m essentially trying to do is to allow the user to select files only from a particular folder (which I set using gtk_file_chooser_set_current_folder ) and disable navigating to other locations on the file system.
This is the standard file chooser dialog :

This is what I need:

It doesn’t look like that is possible with the standard file chooser dialog. For example, here is a document discussing why such a thing would be useful and how it could be implemented, but the idea never made it to fruition.
What you can do, perhaps, is write your own dialog that implements the
GtkFileChooserinterface, based on theGtkFileChooserDialogcode, but hides the location bar and bookmarks list.
