So, let's look at an example, I'm sure it is clearer than my poor
Engrish...

I have a custom widget for wxHtmlWindow in a "html_window" package. Its
__init__.py is:

def initialize():
    import common
    import codegen
    codegen.initialize()
    if common.use_gui:
        import html_window
        return html_window.initialize()

Its codegen.initialize is:

def initialize():
    common.class_names['EditHtmlWindow'] = 'wxHtmlWindow'

    # python code generation functions
    pygen = common.code_writers.get("python")
    if pygen:
        pygen.add_widget_handler('wxHtmlWindow', PythonCodeGenerator())
    cppgen = common.code_writers.get('C++')
    if cppgen:
        cppgen.add_widget_handler('wxHtmlWindow', CppCodeGenerator())
    xrcgen = common.code_writers.get('XRC')
    if xrcgen:
        xrcgen.add_widget_handler('wxHtmlWindow', xrc_code_generator)

Now, as you can see I haven't a Perl code generator (I don't know perl that
much, and I don't use it for GUIs). But if I had one, I would just add a
couple of lines to initialize:

    plgen = common.code_writers.get('perl')
    if plgen:
        plgen.add_widget_handler('wxHtmlWindow', PerlCodeGenerator())

(Of course, assuming I have a proper PerlCodeGenerator defined...)

Is this what you did? If so, can you send me the code so I can look at it?
Because it should work...

Not yet, sorry :-(
