Hi

In AS2, we were able to apply a tween/easing function to the drop-down in a ComboBox with some code like this:

my\_cb.setStyle(“openDuration”, 2000);  
my\_cb.setStyle(“openEasing”, Elastic.easeOut);

[FONT=Verdana]But in AS3, these events are gone.  
Does anyone know how to apply easing to a component in AS3?

Thanks :hat:
