I was thinking about this. One way to save typing
would be to make gtk_object_ref a macro which invokes
_gtk_object_ref, with the proper casts.
#define gtk_object_ref( obj ) _gtk_object_ref( GTK_OBJECT( obj ) )
where _gtk_object_ref is the real C function.
then just call gtk_object_ref() with any object
inherited from GtkObject, and it's done.
This could be used to rid all the "member" function
calls of any casts previously necessary, for a
specific object type. For example:
#define gtk_label_set( label, name ) \
_gtk_label_set( GTK_LABEL( label ), name )
and just call it on a widget pointer, without an
explicit cast.
This would involve alot of work going through
and changing all the "member" function calls,
and you'd still have to use casts for simple
pointer assignments, though, which is sort of
inconsistent.
Peter.
