Re: [flexcoders] Disabling button on buttonBar - error...

Try that.

The problem it's because the buttonBar doesn't have the getChildAt properties it's only reserved to Containers. If you want to use that you have to create new a new override the mx.controls.buttonBar.

But in other way you can try that.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"
width="100%"
height="100%">
<mx:Script>
    <![CDATA[
        import mx.messaging.management.ObjectName;
        import mx.utils.UIDUtil ;
        import mx.core.UIComponent;
        import mx.events.ItemClickEvent;
        import mx.controls.Button;

        [Bindable]
        private function setAble (event:ItemClickEvent):void
        {
            var noAble:Object = this.enabled = false;
            Button(event.index = noAble.item);
        }
    ]]>
</mx:Script>
<mx:ButtonBar id="controlBar" height="20" width="100%"
horizontalGap="0" itemClick="setAble(event);">
<mx:dataProvider>
<mx:Array>
<mx:String >New Topic</mx:String>
<mx:String>Reply</mx:String>
<mx:String>Edit</mx:String>
<mx:String>Delete</mx:String>
<mx:String>Save</mx:String>
</mx:Array>
</mx:dataProvider>
</mx:ButtonBar>

</mx:Application>

Regards.

Hi,

I'm trying to disable a button on a buttonbar but I'm getting an
error... here's what I have:

<mx:ButtonBar id="controlBar" height="20" width="100%"
horizontalGap="0" itemClick="buttonBarClickHandler(event);">
<mx:dataProvider>
<mx:Array>
<mx:String>New Topic</mx:String>
<mx:String>Reply</mx:String>
<mx:String>Edit</mx:String>
<mx:String>Delete</mx:String>
<mx:String>Save</mx:String>
</mx:Array>
</mx:dataProvider>
</mx:ButtonBar>

Then I have this:

import mx.controls.Button;

private function setAccess( accessLevel:String ):void {
switch(accessLevel) {
case "core":
Button(controlBar.getChildAt(1)).enabled = false;
break;
default:
trace("Error setting button states: Out of range");
}
}

The error I'm getting is:

"Call to a possibly undefined method getChildAt through a reference
with static type mx.core:IUIcomponent."

Does anyone know why I'm getting this error - and how I can resolve it
please ?!

Thanks,

Jamie.
