Subject: [flexcoders] Databinding of a read only property
Hi all,
How do I make a read-only property bindable for users of my class?
It sounds so simple but has me stumped at the moment. I'm sure there
must be a simple solution but for the life of me I can't figure it
out...
E.g. say I have a property testProp which is maintained by my class
and must not be publicly set-able from outside. I do however want
outside users to be able to bind to testProp so that they receive
notifications when it changes.
An example of a read-only bindable property would be
ArrayCollection.length. You can bind to this but cannot change it.
How do I do the same thing with testProp?
I tried...
protected var _testVar:uint = 10;
[Bindable]
public function get testVar():uint
{
return _testVar + 1;
}
protected function set testVar(value:uint):void
{
_testVar = value;
}
...hoping to hide the setter from the outside world but outside users
CAN still change testProp with myClassInstance.testProp=10!!
Thanks for your help,
Nick.
