GTK+ Filechooser to open both files and folders

Question

How do I get my filechooser to be able to select both files and folders when the open button on the filechooser dialog is hit ? I want to squeeze the ability to open files and filders in just one filechooser. I am using GTK+ and Python.

Answer 1

I was thinking about this, and although in your comments you've decided to go another route, I do have a suggestion: Write your own file chooser subclass of the GTK+ one and provide two "Open" buttons, one to "Open File" and another to "Open Directory". That would eliminate the ambiguity discussed above.
