python - Accel 在 gedit 3 插件中不起作用

Question

我正在尝试为 Gedit 3 编写一个使用 GObject 自省(introspection)的小插件。下面显示的代码的相关部分旨在建立一个环境，然后我可以在该环境中适应按钮回调中的函数。但是，按钮的加速器不起作用。

1. 这段代码有什么问题？

2. 我正在使用教程 here和 GTK 3 的 python 文档 here .还有其他您知道的链接吗？

   from gi.repository import Gtk, Gedit, GObject 
   ui_string = """<ui>
   <toolbar name="ToolBar">
   <separator />
   <toolitem name="Test" action="Test" />
   </toolbar>
   </ui>
   """
   class test:
       def __init__(self, plugin, window):
           self.window = window
           self.plugin = plugin
           self.ui_id = None
           manager = self.window.get_ui_manager()
           action_group = Gtk.ActionGroup("TestPluginactions")
           action_test_button = Gtk.Action(name="Test",
               label="Test",
               tooltip="Test",
               stock_id=Gtk.STOCK_EXECUTE)
   
           action_test_button.connect("activate", self.testcallback)
           action_group.add_action_with_accel(action_test_button, "<Ctrl>l")
   
           manager.insert_action_group(action_group, -1)
           self.ui_id = manager.add_ui_from_string(ui_string)
           manager.ensure_update()
   
       def deactivate(self):
           manager = self.window.get_ui_manager()
           manager.remove_ui(self.ui_id)
           self.ui_id = None
           self.window = None
           self.plugin = None
   
       def testcallback(self,unused):
           dialog1 = Gtk.MessageDialog(self.window,Gtk.DialogFlags.DESTROY_WITH_PARENT,
               Gtk.MessageType.ERROR,Gtk.ButtonsType.OK,"TEST")
           dialog1.run()
           dialog1.destroy()
   
   
   class WindowActivatable(GObject.Object, Gedit.WindowActivatable):
       window = GObject.property(type=Gedit.Window)
       def __init__(self):
           GObject.Object.__init__(self)
           self.instances = {}
   
       def do_activate(self):
           self.instances[self.window] = test(self, self.window)
   
       def do_deactivate(self):
           if self.window in self.instances:
               self.instances[self.window].deactivate()

知道 GTK 3 有一些错误，不允许以上面显示的方式将快捷方式分配给工具项。然而，菜单项工作正常。所以下面的代码更好。

    from gi.repository import Gtk, Gedit, GObject 
    ui_string = """<ui>
    <toolbar name="ToolBar">
    <separator />
    <toolitem name="Test" action="Test" />
    </toolbar>
      <menubar name="MenuBar">
      <menu name="ToolsMenu" action="Tools">
      <placeholder name="ToolsOps_2">
      <menuitem name="test1" action="test1"/>
      </placeholder>
      </menu>
      </menubar>
    </ui>
    """
    class test:
        def __init__(self, plugin, window):
            self.window = window
            self.plugin = plugin
            self.ui_id = None
            manager = self.window.get_ui_manager()
            action_group = Gtk.ActionGroup("TestPluginactions")
            action_test_button = Gtk.Action(name="Test",
                label="Test",
                tooltip="Test",
                stock_id=Gtk.STOCK_EXECUTE)
            action_test = Gtk.Action(name="test1",
                label="Test",

                stock_id=Gtk.STOCK_EXECUTE)
            action_test_button.connect("activate", self.testcallback)
            action_test.connect("activate", self.testcallback)
            action_group.add_action(action_test_button)
