Re: Setting an iter from an ID value

[Carl Nygard <cjnygard fast net>]

I do some similar contortions in C++ code.  The only seeming difference
is that I maintain the option vector separately from the widget, so I
can just scan through the options and figure the matching index, then
use


        Gtk::Menu* menu = _optionMenu->get_menu();
        menu->set_active(_active);
        menu->activate_item(menu->items()[_active], true);
