很长时间没有摸AS3.0了.自知快要落伍了, 于是下定决心利用有限的业余时间继续研究AS3.0. 整理一些常用的As3.0用法.目前关于AS3按钮的onReleaseOutside,整理了一下.如下:
package {
import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.events.Event;
import flash.display.Stage;
public class Wsbutton extends Sprite {
private var button:Sprite;
public function Wsbutton() {
init();
}
private function init():void {
button=new Sprite();
button.graphics.beginFill(0x000000,1);
button.graphics.drawRect(50,50,200,100);
addChild(button);
button.buttonMode=true;
button.addEventListener(MouseEvent.MOUSE_DOWN,buttonPress);
button.addEventListener(MouseEvent.MOUSE_UP,buttonRelease);
button.addEventListener(MouseEvent.MOUSE_OVER,buttonOver);
button.addEventListener(MouseEvent.MOUSE_OUT,buttonOut);
}
private function buttonPress(e:MouseEvent):void {
this.stage.addEventListener(MouseEvent.MOUSE_UP,buttonRelease);
}
private function buttonRelease(e:MouseEvent):void {
this.stage.removeEventListener(MouseEvent.MOUSE_UP,buttonRelease);
if (e.currentTarget != button) {
trace('onReleasedOutside');
} else {
trace('onRelease');
}
}
private function buttonOver(e:MouseEvent):void {
if (e.buttonDown) {
trace('onDragOver');
} else {
trace('onRollOver');
}
}
private function buttonOut(e:MouseEvent):void {
if (e.buttonDown) {
trace('onDragOut');
} else {
trace('onRollOut');
}
}
}
}
包括了dragover,dragout,onReleaseOutSide等状态.
