Adding the following in clutter-base.defs partially solves the problem:
(define-virtual lower
(of-object "ClutterContainer")
(return-type "none")
(parameters
'("ClutterActor*" "actor")
'("ClutterActor*" "sibling" (null-ok) (default NULL))
)
)
(define-virtual raise
(of-object "ClutterContainer")
(return-type "none")
(parameters
'("ClutterActor*" "actor")
'("ClutterActor*" "sibling" (null-ok) (default NULL))
)
)
This raises another problem. The binding generator adds an _ after raise,
probably because this is a python keyword. I had to remove those _ from the
generated clutter.c to get it compiled. Then it works, the method do_raise
actually gets called.
