[转]FLEX的初始化顺序
<span style="font-family: Verdana, Helvetica, Arial, sans-serif; border-collapse: collapse; color: #444444;"><span style="color: #444444;">From：http://blog.csdn.net/dante_k7/archive/2009/06/18/4275381.aspxFLEX组件在建立的时候都会经历四个事件：preinitialize , initialize , creationComplete 和 updateComplete（updateComplete事件在任何改动视觉的情况下都会发生，不是初始化时独有的）。
下面的例子检测在嵌套和平行的情况下，各个组件的事件抛出顺序。<div style="margin-top: 10px; margin-right: 0px; margin-bottom: 10px; margin-left: 0px; padding-top: 10px; padding-right: 0px; padding-bottom: 5px; padding-left: 10px; line-height: normal; width: 586px; background-color: #f7f7f7; background-position: 0px 0px; border: 1px solid #cccccc;" class="blockcode"><div style="line-height: normal; padding: 0px; margin: 0px;">
