It's doable, but, in C (which is what Ethereal is written in) it's
fairly different in detail:
typedef struct {
GtkWidget *button;
GtkAccelGroup *accel_group;
} fix_label_args_t;
static void
dlg_fix_label(GtkWidget *label_widget, gpointer data)
{
fix_label_args_t *args = data;
gchar *label;
guint accel_key;
gtk_label_get(GTK_LABEL(label_widget), &label);
accel_key = gtk_label_parse_uline(GTK_LABEL(label_widget), label);
if (accel_key != GDK_VoidSymbol) {
/* Yes, we have a mnemonic. */
gtk_widget_add_accelerator(args->button, "clicked", args->accel_group,
accel_key, 0, GTK_ACCEL_LOCKED);
gtk_widget_add_accelerator(args->button, "clicked", args->accel_group,
accel_key, GDK_MOD1_MASK, GTK_ACCEL_LOCKED);
}
}
GtkWidget *
dlg_radio_button_new_with_label_with_mnemonic(GSList *group,
const gchar *label, GtkAccelGroup *accel_group)
{
GtkWidget *radio_button;
fix_label_args_t args;
radio_button = gtk_radio_button_new_with_label (group, label);
args.button = radio_button;
args.accel_group = accel_group;
gtk_container_foreach(GTK_CONTAINER(radio_button), dlg_fix_label, &args);
return radio_button;
}
GtkWidget *
dlg_check_button_new_with_label_with_mnemonic(const gchar *label,
GtkAccelGroup *accel_group)
{
GtkWidget *check_button;
fix_label_args_t args;
check_button = gtk_check_button_new_with_label (label);
args.button = check_button;
args.accel_group = accel_group;
gtk_container_foreach(GTK_CONTAINER(check_button), dlg_fix_label, &args);
return check_button;
}
