for instance via a gtk module like you suggest, and maybe some rc-files if he's doing his own theming/look. > With this API the vendor would need to have a gtk module or library > especially for the gnome-panel in order to appoint a new implementation > of PanelMenu. if he *only* means to change the panel menu yes. if all menus should have the logo, all apps will need the module/library. > It seems to me that, in this case, you'd want PanelMenu to > automatically sub-class the customised GtkMenu implementation. not only want to, but *have* to. it's the only way to ensure a newly plugged type conforms to the required interface (GtkMenu), so appointing a type not derived from GtkMenu for a stock GtkMenu would not work. > I can't > imagine that being practical, though. i don't think there is any alternative to this approach. > Cheers, > Mark. > > [1] - http://www.gnome.org/~markmc/code/panel-menu.c --- ciaoTJ _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
