How do you access private variable in flex?
In Flex, you access a private variable by calling it from within that class. Remember, the "private" modifier means it cannot be directly accessed outside of the class you declare it in (note I say "directly accessed" you can indirectly access it via public functions which I will show below). Example: declare your variable at the top of your class like this: private var myVariable:String; Then, inside one of your functions of that class, you can access the variable and/or assign it this way: public function changeMyVariable(value:String):void { // sets the private variable to a custom string myVariable="test String"; trace("myVariable is set to "+myVariable); // sets the private variable to the argument passed in myVariable = value; trace("myVariable is now set to" +myVariable); }
