Re: [flexcoders] Re: I've got a [Bindable] boolean var - can I setup a eventlistener on it?

In this situation, the easiest way is using ChangeWatcher.watch function to 
watch that variable.

 I've declared a [Bindable] private var changeme:Boolean;

 

 Is there a way to execute a function whenever this var changes?

 

 thanks,

Even easier, would be to change the var to a getter/setter, and execute the 
function in the setter.

 assuming your in the same class as changeme:
 
 private var changemeWatcher:ChangeWatcher;
 
 this.changemeWatcher = ChangeWatcher.watch(this, changeme, 
 changemeChangedFunction);
 
 this function will get called every time it changes:
 private function changemeChangedFunction(event:PropertyChangeEvent):void
 
 when you are done, make sure to uregister it with
 this.changemeWatcher.unwatch();
