[Jython-users] Explicitly creating listeners from callables

[Michael H. <hag...@jp...>]

Hello,

Is there a way to access jython's "callable-to-listener" conversion
explicitly?

I would like to do this:

class C:
    def __init__(self):
        # ...
        b = JComboBox(actionPerformed=self.doIt)
        # ...

    def doIt(self, e):
        # ...

but it doesn't work because JComboBox (oddly) defines an
actionPerformed method.  (See

    http://aspn.activestate.com/ASPN/Mail/Message/Jython-users/541301

for more information.)

Is there a way to access jython's "callable-to-listener" conversion
explicitly?  If so, I could do

    b = JComboBox(actionListener=jython_coersion(actionPerformed=self.doIt))

which is not quite as terse as the original, but at least better than
having to define a python wrapper class to do the trick (and probably
a bit faster, too).  Ideally this would be spelled

    b = JComboBox(actionListener=ActionListener(actionPerformed=self.doIt))

but unfortunately this produces an error

    TypeError: can't instantiate interface (java.awt.event.ActionListener)

Thanks,
Michael
