As the doc says, an ADD event happens as a result of a call to addChild
From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of gwangdesign Sent: Friday, August 22, 2008 10:31 AM To: [email protected] Subject: [flexcomponents] Please: Help me understand "add"/"remove" event I am having a hard time understanding "add" and "remove" event for UIComponents. What do they mean and when do they happen? After testing in the debugging console, it seems for the same component, the "add" event is dispatched before the "preintialize" event. So I assume that an "add" event happens when Flex calls the "addChild" to add the component to the DisplayList; similar story happens for an "remove" event. But further investigation reveals that if a Container with all its inner components is attached to an "AddChild" node under a "State" node under one pass, its descendant components "add" events happen before the container's "add" event. In the following code, the "add" events for "tXt1" and "bTn1" happen before the "add" event for the "vBx1": <mx:State name="block"> <mx:AddChild> <mx:VBox id="vBx1" width="100%" height="100%" add="addLog(event);" remove="removeLog(event);"> <mx:Text id="tXt1" text="Hello world!" styleName="embFont" add="addLog(event);" remove="removeLog(event);"/> <mx:Button id="bTn1" label="Back" click="currentState=null" styleName="embFont" add="addLog(event);" remove="removeLog(event);"/> </mx:VBox> </mx:AddChild> </mx:State>
