嗯...這只是一個懶人小技巧，為了就是省下作 Button enaqbled=false 時的灰階 Icon 圖...( 這個作法是將 disable 狀態直接都變成灰階的...所以設 disable 文字顏色也沒用喔...XD ) 原理蠻簡單的就是 override 掉 updateDisplayList 這個 function ( override enabled setter 也可行) /* LazyButton Copyright (c) 2009 Erin Lin ( Yu-Shan Lin) Your reuse is governed by the Creative Commons Attribution 3.0 License 最近大家都很愛寫CC license 所以我也來寫一下...XD enabled = false; 變灰階 */ package { import mx.controls.Button; import flash.filters.ColorMatrixFilter; public class LazyButton extends Button { public function LazyButton() { super(); } override protected function updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth, unscaledHeight); if(!enabled){ filters = [new ColorMatrixFilter( [0.3086,0.6094,0.0820,0,0, 0.3086,0.6094,0.0820,0,0, 0.3086,0.6094,0.0820,0,0, 0,0,0,1,0])]; }else{ filters = []; } } } }
