[Glade-users] How-to define my own class inheriting from gtk.Window and using glade file

[Dominique Beauchamp]

Thanks for the fast answer.

Here is what I did:

1) I copied pythonplugin.py and pythonplugin.xml as shown in the example in
a directory XYZ
2) I defined an environment variable named GLADE_ENV_CATALOG_PATH = XYZ
(where my .py and my .xml are)
3) I started Glade (3.7.3) Where is my widget?

In the xml, I find this:

<glade-widget-group name="python" title="Python">
   <glade-widget-class-ref name="MyBox"/>
 </glade-widget-group>

I guess I should have a group (or a tab) named "Python" with a widget named
"MyBox" but I don't. What did I do incorrectly?
