DropDown events

Can anyone point me to information about DropDown events? I would like to handle when the selection in the dropdown has changed. 

 

            myDropDown.addEventListener(Event.SELECT, myFunction, true, 0, true);

 

The above doesn't do the trick.  I can see MouseEvents.CLICK events if I change the event above.

Thanks in advance.

hey kaptuafj,

 

according to the API reference page:

 

http://www.blackberry.com/developers/docs/airapi/1.0.0/qnx/ui/listClasses/DropDown.html

 

the event that should be listened to for is Event.SELECT. I'll write out a program and run it to confirm.

 

Edit: Just ran the program and it runs fine. Event is fired and caught. just make sure your listener function looks something like this with the event in parenthesis:

 

 

public function myFunction(e:Event):void

 

Edit #2: Hey just used your line:

 

 

myDropDown.addEventListener(Event.SELECT, myFunction, true, 0, true);

 

 

and it started not working. if you set the usecapture argument to FALSE it will start working. unless you have a specific reason to setting it to be true, usually that option is set to false by default. also unless you need all those arguments usually just using this line does the trick:

 

 

myDropDown.addEventListener(Event.SELECT, myFunction);

 

 

here is the detail for the usecapture argument if you need a deeper look:

let me know if that works!
