Hi Peter.
I tried your solution and I think gtk_server_redefine works perfectly.
I have another strange issue: gtk-server core dumps where I call the
redefined gtk_list_store_new.
I attach a file with the communication between gtk-server and the wrapper:
Then the gtk-server goes to core dump.
64 is the number for G_TYPE_STRING: i've checked with a c program.
I'm in windows with gtk-server 2.0.6 and gtk 2.6.7.
Probably the solution is easy....
When I've more time I will check on linux in order to see the stack trace.
Thanks again,
Leonardo

Hi Leonardo,
Well, you are completely right there! I have cut and pasted from old code.
But
the GTK-server expects the incoming call without commas.
Sorry for the confusion.
Regards
Peter
