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

Thanks. I had some difficulties to find how to set new env. variables on
Ubuntu but it is not the point...

What was not clear in the doc was that I beleived I had to have one catalog
(xml) per class (widget). I is clear (maybe I'm wrong) that the best way is
to have a master .py file that imports all the other widget python files and
one catalog file with multiple class entries. Maybe this should be made
clearer in the doc.

Anyway, it works fine! Thank you!

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)


Sorry, the docs in that version have a typo, it should be
 "GLADE_CATALOG_PATH"  (with no _ENV).


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?

        Yes, you can define classes in python and use them in Glade
        and GtkBuilder.

        For PyGTK & GTK+2 you must use Glade 3.6 or 3.8, if you
        migrate to
        PyObject & GTK+3
        then you must use Glade 3.10.

        There is an example of how to setup Glade so that your custom
        python widgets
        show up in Glade's palette, in Glade's API reference here:

         http://library.gnome.org/devel/gladeui/3.6/pythonsupport.html

        Basically you just have to define a short xml catalog and have
        it in
        GLADE_CATALOG_PATH
        when firing up Glade, and have a copy of the python source in
        the same
        directory.

        Enjoy,
            -Tristan
