Passive Methods

Nautilus.PropertyPageProvider.get_pages

    def get_pages()

files :

a list of Nautilus.FileInfo objects.

Returns :

a list of Nautilus.PropertyPage objects

This function is called by Nautilus when it wants property page items from the extension. It is called in the main thread before a property page is shown, so it should return quickly.
