The list classes set .visible on renderers as part of the recycling, so we're overriding yours.
You should be able to set it in commitProperties or later. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Scott - FastLane Sent: Monday, September 17, 2007 3:32 AM To: [email protected] Subject: [flexcoders] Invisible checkbox renderer I am attempting to optimize my renderers in an AdvancedDataGrid. The following code works perfectly, but it seems I should be able to do this without the overhead of an HBox. So... I have implemented the following code and am having trouble seeing why it won't work. If I debug, I see that this.visible is being set to false... but it always appears anyway. Seems this should be very simple, I must be overlooking something. Any Help is appreciated. Scott *** This works, but is heavier weight *** <mx:itemRenderer> <mx:Component> <mx:VBox verticalScrollPolicy="off" horizontalScrollPolicy="off" horizontalAlign="center"> <mx:Script> <![CDATA[ import fastlane.data.Task; //hide the checkbox if this is a task public override function set data(value:Object):void { var isTask:Boolean = value is Task; this.checkBox.visible = (!isTask); super.data = value; } ]]> </mx:Script> <mx:CheckBox id="checkBox" selected="{data.isSelected}" labelPlacement="left" click="parentDocument.setItemSelected(data, event)"/> </mx:VBox> </mx:Component> </mx:itemRenderer> *** Would prefer this if it worked *** public class MyCheckBox extends CenteredCheckBox { /** * Called when the data is set. */ public override function set data(value:Object):void { var isTask:Boolean = value is Task; this.visible = !(isTask); this.invalidateProperties(); //note: have tried invalidateDisplayList() and UIComponent(this.parent).invalidateDisplayList() as well super.data = value; } }
