making a window transient

[Grace Yeung <yeung mrcmry com>]

I am using a gnome_file_entry widget for the capability of browsing
directories.  With this widget, the user can create a new directory by
clicking on the built-in Create Dir button which brings up another
window.  However, this window that is created internally does not stay
on top of the parent window.  Is there a way to access this window so I
can do a gtk_window_set_transient_for()?  Or is there another way of
fixing this problem?  Thanks.
