Re: [flexcoders] Event Handlers inside custom components

I actually figured this out right after I asked but I did it a different way.
It does basically the same thing though.
 
Here is an example:

To make the component's property bindable, specify a "ChangeEvent" for
the property and dispatch the event when the value changes.

e.g.


http://www.macromedia.com/2003/mxml"; xmlns="*">
  
  

// Storage for 'labelText' property
private var _labelText:String = "";

[ChangeEvent("labelTextChange")]
public function get labelText():String
{
  return _labelText;
}
public function set labelText(value:String):Void
{
  if (value != _labelText)
  {
_labelText = value;
dispatchEvent({type: "labelTextChange"});
  }
}
  


When labelText is modified, the component dispatches an event to
trigger binding.  Check out the generated AS to see how this works.

Yes,

using object.watch(prop, callback [, user data])
