[flexcoders] Re: Loop through all visual components
Still not success. I gave an example.
My user enter something e.g. login name and
then program display the full name.
private function DoChecking(S:String):String {
...
if (TryOnce) then {
return Already Tried;
}
else {
return First Time;
}
}
mx:Label id=ShowName text={DoChecking(login)}/mx:Label
First time is ok but when another button is clicked and change
the variable TryOnce. The label 'ShowName' cannot be refreshed
eventhough I use ShowName.validatedisplaylist(). I also tried
validatenow()but not successAny help ?

I have created a custom button and used it
throughoutly in my FLEX application. How
can I change it dynamically by looping through
all components ? Is there any like children
stuff and then use ValidateDisplayLis t to
make it refresh ? Actually, it likes changing
the skin dynamically. But I need to check the
content of button before modification.
Having example is great. Thanks in advance.
Re: [flexcoders] Re: Loop through all visual components
Not sure but I think you need to make your login variable (whather that is)
bindable, so that, when it changes, the showName label is notified:
[Bindable]
private var login:String; // just guessing the declaration. The important part
is the [Bindable] tag

[flexcoders] Re: Loop through all visual components
Thank you. Through your lens, I did it by :- 1. Make a custom component with custom properties 2. Make that properties be [Bindable] 3. Write a private function to change what I need while the cusom properties change. Then, no need to loop through all component, and no need to use function like validatenow(), invalidatedisplaylist() Thank you !
