hello,
would it be possible to change dispatch event in event.py to something
like the following? The added return statements allow for more
complicated event structures.
def dispatch_event(self, event_type, *args):
'''Dispatch a single event to the attached handlers.
The event is propogated to all handlers from from the top of the stack
until one returns `EVENT_HANDLED`. This method should be used only by
`EventDispatcher` implementors; applications should call
the ``dispatch_events`` method.
:Parameters:
`event_type` : str
Name of the event.
`args` : sequence
Arguments to pass to the event handler.
'''
assert event_type in self.event_types
# Search handler stack for matching event handlers
for frame in list(self._event_stack):
handler = frame.get(event_type, None)
if handler:
try:
if handler(*args):
return True
except TypeError:
self._raise_dispatch_exception(event_type, args, handler)
# Check instance for an event handler
if hasattr(self, event_type):
try:
return getattr(self, event_type)(*args)
except TypeError:
self._raise_dispatch_exception(
event_type, args, getattr(self, event_type))
return False
