[Glade-users] adding custom widgets

[Gerald Britton]

OK -- I found I needed an additional package (libgladeui-1-dev)

Now I'm trying to set up a catalog.  The difficulty for me at this
point is that I want to use it with Python.  Following the docs, and
another tutorial I found,

http://unpythonic.blogspot.com/2007/03/custom-pygtk-widgets-in-glade3.html

I built a catalog, adding language="python" to the glade-catalog
element.  But, I can't see how the Python code for the module would
work, knowing what I do about Python imports.

I'd sure love to see an end-to-end example.  Starting with vanilla
glade-3, add a catalog and custom widgets, build a glade file using
glade-3 using the custom widgets then see what the gtk+ application
code looks like -- all with Python as the implementation language.
