用法：在stage裡拖入一個UIObject和一個MC
在AS幀加入以下代碼
import DbClick;
DbClick.init(_btn);
DbClick.init(_mc);
//
onSiClick = function (evtObject:Object) {
evtObject.target.label = "Single Click";
};
onDbClick = function (evtObject:Object) {
evtObject.target.label = "Double Click";
};
//
_btn.addEventListener("onSiClick", this);
_btn.addEventListener("onDbClick", this);
//
function McSingleClick(evtObject:Object) {
trace("MC:"+evtObject.target.txt)
evtObject.target.txt.text = "Single Click";
}
function McDoubleClick(evtObject:Object) {
evtObject.target.txt.text = "Double Click";
}
_mc.addEventListener("McSingleClick", this);
_mc.addEventListener("McDoubleClick", this);
