Question

我试图为Gedit 3编写一个使用GObject内省的小插件。下面显示的代码的相关部分只是为了获得一个环境，然后我可以在按钮的回调中适应函数。但是，按钮的加速器不起作用。

此代码有什么问题？

我正在使用教程here和GTK 3 here的python文档。你知道其他任何链接吗？

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()

要知道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品。但菜单项工作正常。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",
                tooltip="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)
            action_group.add_action_with_accel(action_test, "<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.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()

Accel不在gedit 3插件中工作
