[flexcoders] Re: Flex2 ButtonBar; Can its buttons be individually enabled or disabled?

2006-04-24 Thread wlbagent 



Mike, thanks for the reply. I made a couple of attempts at casting to
a button but I must be missing something. Here is a simple example of
what I'm talking about. If any row is selected in dg, then all
buttons except button A should be disabled. What do I need to do to
make this happen?
Thanks, Bill...

  For example. You have a ButtonBar with 4 buttons labeled
  A,B,C,and D. You want button A to always be enabled but the
  remaining buttons would be enabled or disabled based on some other
  condition. You might have a DataGrid and want B,C,and D enabled
  if a row is selected, otherwise they are disabled.
 
  This should be a fairly easy thing to do if its actually possible. I
  can reference the individual buttons but there doesn't seem to be an
  enabled property for them. What have I missed??
 
  Any ideas???

You need to import the Button class, and then you can try something like
this:



?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml xmlns=*
layout=vertical
mx:Script
 ![CDATA[
 import mx.events.ItemClickEvent;
 import mx.events.ListEvent;
 // Add this import
 import mx.controls.Button;

 private function
btnbarEvent(event:ItemClickEvent):void{
 ta.text=btnbar selected index is
+event.index.toString();
 }

 private function dgEvent(event:ListEvent):void{
 ta.text=dg selected index is
+event.rowIndex.toString();
 var childA:Button= btnbar.getChildAt(0) as
Button;
 var childB:Button=
btnbar.getChildAt(1) as Button;
 var childC:Button=
btnbar.getChildAt(2) as Button;
 var childD:Button=
btnbar.getChildAt(3) as Button;



 childB.enabled=false;
 childC.enabled=false;
 childD.enabled=false;


 }

2006-04-24 Thread wlbagent 



Thanks, Oscar (and Mike). 

This does answer my question. I was looking for something more
dynamic, though, in case buttons were added or removed. I'll tinker a
bit more (btnbar.numChildren, etc) but thanks for the jump start.
