Re: [問題] 按下按鈕後 讓按鈕停留在按下的狀況

[DLMC (永保安康)]

※ 引述《clas (克雷斯)》之銘言：
: 請問怎麼樣做才可以在按下按鈕後讓按鈕停留在按下的狀態
: 然後再按一下 可以回復為原始未按下的狀態
: 我想破頭了
: 請教各位先進 感謝~~

以下是純AS3的作法：

雖然有人說flash的按鈕不好用(意即SimpleButton Class)，
但其實如果要很快開發介面用的工具，其實也不錯用。

以下是一個簡單的OnOffButton Class，剛好滿足clas的需求：

package{
   import flash.display.SimpleButton;
   import flash.display.Loader;
   import flash.events.MouseEvent;

   public class OnOffButton extends SimpleButton{
      private var onOffIndex:Boolean

      //ON狀態按鈕
      private var normalLoader:Loader;
      private var overLoader:Loader;
      private var downLoader:Loader;

      //OFF狀態按鈕
      private var normalLoaderOff:Loader;
      private var overLoaderOff:Loader;
      private var downLoaderOff:Loader;

      public function OnOffButton(onOff:Boolean){
         onOffIndex=onOff;

         normalLoader=new Loader(new URLRequest("ON 平常狀態圖檔");
         overLoader=new Loader(new URLRequest("ON 滑鼠移入狀態圖檔");
         downLoader=new Loader(new URLRequest("ON 滑鼠按下狀太圖檔");

         normalLoader=new Loader(new URLRequest("OFF 平常狀態圖檔");
         overLoader=new Loader(new URLRequest("OFF 滑鼠移入狀態圖檔");
         downLoader=new Loader(new URLRequest("OFF 滑鼠按下狀太圖檔");

         switchOnOff(onOffIndex);

         this.addEventListener(MouseEvent.Click, mouseClickHandler);
      }

      public function switchOnOff(onOff:Boolean):void {
         if (onOff == true) {
            this.hitTestState = normalLoader; //設定感應區域

            this.upState = normalLoader;
            this.overState = overLoader;
            this.downState = downLoader;
         }else {
            this.hitTestState = normalLoaderOff; //設定感應區域

            this.upState = normalLoaderOff;
            this.overState = overLoaderOff;
            this.downState = downLoaderOff;
         }
      }

      private function mouseClickHandler(e:MouseEvent):void{
         onOffIndex=!onOffIndex;
         switchOnOff(onOffIndex);
      }
   }
}






使用上只要宣告var onOffButton:OnOffButton=new OnOffButton(true); //初始為ON
就可以用On / Off button了:>

(我自己會加上一些初始屬性，如這個按鈕會不會有over或down的狀態)
(有興趣可跟我要AS檔)
