GtkUIManager与GtkActionEntry的问题，Action不能响应(已经解决)

chenzhixin

我在gtk_widget_show(wbus->window);之前调用了wbus_init_actions，可我按下ctrl+c的时候并不会打印出东西



//menu activate callbacks
void on_menu_start_vidcap_activate(GtkMenuItem *item ,gpointer data)
{
        dprintk("ASDLFJALSDFJALDFLAK\n");
}

void on_menu_stop_vidcap_activate(GtkMenuItem *item,gpointer data)
{


}

/* menuitem definition */
GtkActionEntry wbus_test_actions[] = {
        /* Action name, stock ID, label, accelerator, tooltip, callback */
        {"start_vidcap",NULL,N_("start video capture"),"<control>c",NULL,G_CALLBACK(on_menu_start_vidcap_activate)},
        {"stop_vidcap",NULL,N_("stop video capture"),"<control>s",NULL,G_CALLBACK(on_menu_stop_vidcap_activate)},
};

char* wbus_test_menu_ui = {
        "<ui>"
        "        <menu name='test'>"
        "                <menuitem action='start_vidcap'/>"
        "                <menuitem action='stop_vidcap'/>"
        "        </menu>"
        "</ui>"
};

void wbus_init_actions(const char *ui,GtkActionEntry *entries)
{
        wbus->action_group = gtk_action_group_new("Actions");
        gtk_action_group_set_translation_domain(wbus->action_group,GETTEXT_PACKAGE);
        gtk_action_group_add_actions(wbus->action_group,entries,G_N_ELEMENTS(entries),NULL);

        wbus->ui_manager = gtk_ui_manager_new();
        gtk_ui_manager_insert_action_group(wbus->ui_manager,wbus->action_group,0);

          if((gtk_ui_manager_add_ui_from_string (wbus->ui_manager,ui, -1, NULL)) < 0){
                dprintk("WBUSCANNER: can't add ui from string\n");
        }

        wbus->ui_id = gtk_ui_manager_new_merge_id (wbus->ui_manager);

        /* Bind the accelerators */
        gtk_window_add_accel_group(GTK_WINDOW(wbus->window),gtk_ui_manager_get_accel_group(wbus->ui_manager));

        /* Do this so that the menu is packed now instead of in the idle loop */
        gtk_ui_manager_ensure_update(wbus->ui_manager);
       
        return;
}

void wbus_remove_actions(void)
{
        gtk_ui_manager_remove_ui(wbus->ui_manager,wbus->ui_id);
        g_object_unref(wbus->action_group);
        g_object_unref(wbus->ui_manager);
}

已经解决，主要是
GtkActionEntry wbus_test_actions[] = 这个长度取值错误了。G_N_ELEMENTS(entries)，直接G_N_ELEMENTS(wbus_test_actions);
