i've created simple app skeleton in python 2.7 using pygtk , glade (3.16.1) on ubiuntu 14.04 lts. i've added toolbar , buttons, gtktoolbutton disabled. how can enable them glade?

my gui toolbutton disabled my gui toolbutton disabled

i've tried in python using "set_sensitive" nothing works.

can me? thank much!

this snippet glade file:

<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 not straightforward use. have create corresponding action. simple example of how use them:

the glade file:

<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>

the python file:

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()

you can have @ example application menu similar
