Exactly as Karl said, a WidgetsDeclaraion instance is just a list and
you can anything you can do with a list with it.
Example:
>>> from turbogears import widgets as w
>>> from turbogears.widgets import WidgetsDeclaration as WD
>>> class CommentFields(WD):
... name = w.TextField()
... comment = w.TextArea()
...
>>> class OtherFields(WD):
... special = w.TextArea()
...
>>> fields = CommentFields() + OtherFields()
>>> for field in fields:
... print field.name
...
name
comment
special
>>> fields.append(w.CheckBox(name="jorge"))
>>> for field in fields:
... print field.name
...
name
comment
special
jorge
>>>
