After some tinkering I came up with an ugly, but legal
and working solution.
Hopefully this will help others in the same situation.
Almer. S. Tigelaar.
/**
* option_menu_index:
* @optionmenu: a gtkoptionmenu
*
* Tries to find out (in an ugly way) the selected
* item in @optionmenu
*
* Return value: the selected index
**/
static int
option_menu_index (GtkOptionMenu *optionmenu)
{
GtkMenu *menu;
GtkMenuItem *selected;
GList *iterator;
int index = -1;
int i = 0;
g_return_val_if_fail (optionmenu != NULL, -1);
menu = (GtkMenu *) gtk_option_menu_get_menu (optionmenu);
iterator = GTK_MENU_SHELL (menu)->children;
selected = (GtkMenuItem *) gtk_menu_get_active (menu);
while (iterator) {
if (iterator->data == selected) {
index = i;
break;
}
iterator = iterator->next;
i++;
}
return index;
}
