flex 介面初始化有時那個標準的進度條無法顯示,介面長時間會處理空白的狀態!我們來自定義乙個進度條,
它就可以比 flex 自執行的正常顯示。

4.呼叫方法
...preinitialize="preinit(event, '')"
privatefunction preinit(event:event, msg:string):void
修改flex預設loading
一 二 flex應用看久了,乙個預設的裝載loading介面就會導致審美疲勞,下面提供一種方法,讓你可以自定義你的裝載介面。1,在src目錄下建立自定義類,兩個檔案 如下 preloader.as package com.preloader override public function set ...
flex 自定義元件的編寫
使用flex也很久了,也改過別人寫的flex自定義元件,但是就是沒有系統的研究下flex元件的編寫步驟,和要注意的東西,在這裡我參照一本書中的例子,好好的理解下,也為了鞏固下自己對flex的理解!1,重寫乙個元件系統依次呼叫constructor 構造方法 createchildren commit...
