Dear
We know in zkoss 6++ SelectorComposer we can annotate a method to listen to any component. The syntax rule is @Listen( event-name = ids / classes / component tags )
what if i want to listen to the self component? I Tried @Listen("onMyEvent=self") and it doesn't work.
I Have fired this event using Events.echoEvent("onMyEvent",getSelf(),null);
please help. manythanks
I am not sure but i suppose that you are creating some components dynamically and you need to assign an event listener to these components. Maybe something like this would do the trick:
Tags
People
Badges
Help
@Listen("onClick = #buttonsDiv > button")
Assuming that the 'buttonsDiv' is the id of the parent component containing the dynamically created buttons.
Hope that helps

Thanks for quick response. but that is what really I mean, we know a self component is a root component of a zul, this component can be refered with 'getSelf()' method of a SelectorComposer subclass. I want to send event to this root comp (the self), don't know how to refer to this 'self' in @Liste

@Listen("onClick = #childWindowButton")
public void onClick_childWindowButton(Event event) {
Component parentComponent = event.getTarget().getParent()...getParent();
Events.postEvent("onChildButtonClicked", parentComponent)
}
And then assign a listener for this event to the root component:
@Listen("onChildButtonClicked=#rootWindow")
public void onChildButtonClicked() {
...do what you have to do...
}
Hope that helps.
