定义一个对象变量（通过转换），可是不执行对象里的方法.原因

[fayewang]

such as:

_tabMenu = (classes.application.TabContainer)(_container.attachMovie("TabContainer", "tabMenu_mc", 21, {_x: 126, _y: 313}));
_tabMenu.Initialize(this);

以下是 class classes.application.TabContainer extends MovieClip
{
var _container, tabButton, _Data, attachMovie, _indc;
function TabContainer()
{
super();
} // End of the function
function Initialize(container)
{
_container = container;
tabButton = new Array();
_Data = classes.application.WideScreen.XMLData;
this.selectIndcSetting();
this.tabSetting();
} // End of the function
...
}
构造函数会执行,而 Initialize 不执行..想知道原因,谢谢
