stan.Proto takes a tag name, so you would really want
just stan.Proto('athena:handler'). However, there's already one of these
in athena, so you can just do:
from nevow import stan, athena
# ...
T.input(type='text', _class='sw-input')[
athena.handler(event='onkeypress', handler='keypressed']
Thanks, Tristan; that's certainly a step forward: the tag is now being
recognised and replaced. However, it's not quite perfect yet: the generated
HTML is escaped:
_handler = athena.handler ( event = 'onkeypress', handler = 'keyPressed' )
...
T.input ( _class = "sw-input", type = "text" ) [ _handler ],
Results in:
<input type="text" class="sw-input" onkeypress="return
Nevow.Athena.Widget.handleEvent(this, "onkeypress",
"keyPressed");" />
Should I be wrapping it in anything else (T.raw()?).
Are you sure this is causing a problem? It looks correct to me. :)
<tag onkeypress="return foo("bar")"> would seriously confuse an html parser.
