[pygtk] pygtk-codegen, enum/flags issue

[Magnus Therning]

There's a patch for libwnck so that it implements a method for setting
the geometry for a window (wnck_window_set_geometry() in the patch for
GNOME bug 342899[1]). In my attempts to add a python binding for this
I've run into some problems with one of the enums:

 wnck.c: In function '_wrap_wnck_window_set_geometry':
 wnck.c:1562: error: 'WNCK_TYPE_WINDOW_MOVERESIZEMASK' undeclared (first use in this function)
 wnck.c:1562: error: (Each undeclared identifier is reported only once
 wnck.c:1562: error: for each function it appears in.)
 wnck.c: In function 'pywnck_add_constants':
 wnck.c:2009: error: 'WNCK_TYPE_WINDOW_MOVERESIZEMASK' undeclared (first use in this function)

The patch is at the end of the email.

I have two questions:
 1. What's the difference between enum and flags for pygtk-codegen, and
    when should I use which?
 2. How do i derive the gtype-id? (I seem to have done it right for
    WnckWindowGravity but not for WnckWindowMoveResizeMask.)
