The reason that components do not create their children immediately when they are created is so that you can set properties after calling 'new' and have these properties affect which children get created. For example, var clock:Clock = new Clock(); clock.mode = "analog"; addChild(clock); The Clock would need completely different children if the mode were "digital" instead of "analog". By delaying the creation of the children until addChild(), the framework makes it possible to optimize which children are created. - Gordon ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of bhaq1972 Sent: Monday, April 30, 2007 4:57 AM To: [email protected] Subject: [flexcoders] creating instances, addChild question This question is very similar to a question someone else is asking (may even be the same thing????)
