Do you really need a class?

You can create widget as a simple function as shown in the book. I say that
because it easier to show you how to set default value with a simple
function (less code)...

def mysupercustomwidget(field, value, ...)
    ...
    if value is not None and value != '':
        field_value = value
    INPUT(..., value=field_value)
    ...

Hope it helps.

Richard
