Comment (by chrisz):
TG 1.0 is actually in feature freeze since many months; such things should
go into 1.1.
But I'm not convinced that this feature should be included because it
makes things more complicated. I'm all for keeping things simple and
consistent - there are several other places (e.g. widget parameters) where
we take callables, and they do not get parameters passed either. Neither
does !ToscaWidgets with which I'd like to stay compatible where possible.
Also, it's easy to achieve the same effect with a plain callable already.
Here is an example where I pass the corresponding form widget instance
(not the field instance which I think is less interesting):
{{{
class MyForm(widgets.TableForm):
def mydefault(self):
return "Bozo" # we could use self here
fields = [widgets.TextField('name')]
myform=MyForm()
myform.fields[0].default = myform.mydefault
}}}
