Question

我在Ubiuntu 14.04 LTS上使用pyGtk和Glade（3.16.1）在python 2.7中创建了一个简单的应用程序框架。我添加了一个ToolBar和一些按钮，但gtkToolButton总是被禁用。如何从Glade启用它们？

my gui with toolbutton disabled

我在python中也尝试使用“set_sensitive”，但没有任何作用。

你能帮帮我吗？非常感谢你！

这是来自glade文件的片段：

<child>
      <object class="GtkToolbar" id="toolbar1">
        <property name="visible">True</property>
        <property name="can_focus">False</property>
        <property name="toolbar_style">both-horiz</property>
        <property name="show_arrow">False</property>
        <style>
            <class name="primary-toolbar"/>
        </style>
        <child>
          <object class="GtkToolButton" id="toolbutton1">
            <property name="name">bt1</property>
            <property name="visible">True</property>
            <property name="can_focus">False</property>
            <property name="is_important">True</property>
            <property name="action_name">bt1</property>
            <property name="label" translatable="yes">toolbutton1</property>
            <property name="use_underline">True</property>
            <property name="stock_id">gtk-connect</property>
            <signal name="clicked" handler="on_toolbutton1_clicked" swapped="no"/>
          </object>

GtkToolbars使用起来不是很简单。您必须创建相应的操作。这是一个如何使用它们的简单示例：

林间空地文件：

<interface>
  <requires lib="gtk+" version="3.16"/>
  <object class="GtkWindow" id="window">
    <property name="can_focus">False</property>
    <child>
      <object class="GtkToolbar">
        <property name="visible">True</property>
        <property name="can_focus">False</property>
        <child>
          <object class="GtkToolButton">
            <property name="visible">True</property>
            <property name="can_focus">False</property>
            <property name="action_name">app.zoom</property>
            <property name="label" translatable="yes">zoom</property>
            <property name="use_underline">True</property>
            <property name="stock_id">gtk-zoom-in</property>
          </object>
          <packing>
            <property name="expand">False</property>
            <property name="homogeneous">True</property>
          </packing>
        </child>
      </object>
    </child>
  </object>
</interface>

python文件：

from gi.repository import Gtk, Gio

class Application(Gtk.Application):

    def do_activate(self):
        action = Gio.SimpleAction.new('zoom', None)
        action.connect('activate', self.on_zoom)
        self.add_action(action)

        builder = Gtk.Builder.new_from_file('window.glade')
        window = builder.get_object('window')
        window.show_all()
        self.add_window(window)

    def on_zoom(self, action, param):
        print('clicked')


if __name__ == '__main__':
    Application().run()

GtkToolButton默认在glade3 + pygtk中被禁用
