No, I use a very simple UI definition format that I invented myself,
it's nothing fancy, in python it looks like this for forms:
fiels = [ dict( type='text', name='name', label='Your Name',
not_empty=True ), ........ ]
so it's a list of dicts, each dict defining a form entry. For example
a radio button is defined like this:
dict(
type='radio',
name='sex',
label='Sex',
value=[
dict( name='male', label='Male', checked=False ),
dict( name='female', label='Female', checked=False ) ],
not_empty=False )
These is then parsed by javascript in an obvious way, without using
any library. The desktop app is also written in python and this python
app parses the above list the same way and presents the user with the
appropriate form.
There are sophisticated xml formats for storing all sorts of
sophisticated UI's (for example wx does this I think) but this kind of
stuff is too heavy weight for me, all I need are forms, for which the
above very simple model is sufficient.
Cheers,
Daniel
