Question

我正在尝试设置垂直条（activityBar）的高度，但它似乎没有做任何事情。我尝试过与整个组件类似的东西，但设置维度什么都不做（甚至在用于实例化类的mxml中）。实际上，我添加了透明图形只是为了给组件一些维度

我不确定我做错了什么。虽然这很糟糕;我的做法似乎很可怕。

仅供参考：我正在尝试创建一个麦克风活动栏，通过简单设置activityBar子项的高度来响应麦克风（这对我来说似乎比每次重绘图形更有效）。

感谢您的帮助！

package components {

  import mx.core.UIComponent;

  public class MicActivityBar extends UIComponent {        
    public var activityBar:UIComponent; 

    // Constructor

    public function MicActivityBar() {

        super();

        this.opaqueBackground = 0xcc4444;

        graphics.beginFill(0xcccccc, 0);

        graphics.drawRect(0,-15,5,30);

        graphics.endFill();// background for bar 

        activityBar = new UIComponent();
        activityBar.graphics.beginFill(0xcccccc, 0.8);
        activityBar.graphics.drawRect(0,-15,5,20);
        activityBar.graphics.endFill();
        activityBar.height=10;

        addChild(activityBar);

    }
  }
}

package components {

  import mx.core.UIComponent;

  public class MicActivityBar extends UIComponent {        
    public var activityBar:UIComponent; 

    private var _w:Number;


    // Constructor

    public function MicActivityBar() {

        super();

        this.opaqueBackground = 0xcc4444;

        graphics.beginFill(0xcccccc, 0);

        graphics.drawRect(0,-15,5,30);

        graphics.endFill();// background for bar 

        activityBar = new UIComponent();
        activityBar.graphics.beginFill(0xcccccc, 0.8);
        activityBar.graphics.drawRect(0,-15,5,20);
        activityBar.graphics.endFill();
        activityBar.height=10;

        addChild(activityBar);

    }

    public function get w():Number {
    return _w;
    }

    public function set w(value:Number):void {
     _w = value;
    }

    override protected function updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void {
           super.updateDisplayList(unscaledWidth, unscaledHeight);

    this.height=w;
    this.weight=w;
}
}
}
