我的应用程序的舞台大小为1000×500，2推出。本机窗口有系统镶边，这将永远是一个高一点几个像素。

怎么可能只允许本机窗口，以便始终保持2比例调整：舞台1宽高比

我希望以下code不工作：

 包
{
//进口
进口flash.display.NativeWindow在;
进口flash.display.Sprite;
进口flash.display.StageAlign;
进口flash.display.StageScaleMode;
进口对象类型：flash.events.Event;
进口flash.events.NativeWindowBoundsEvent;

//类
[SWF（宽度=1000，高度=500，帧率=60的backgroundColor =＃000000）
公共类WindowTest扩展Sprite
    {
    //常量
    私有静态常量ASPECT_RATIO：数= 2.0; // 2：1宽高比

    //构造函数
    公共职能WindowTest（）
        {
        在里面（）;
        }

    //初始化
    私有函数的init（）：无效
        {
        在Stage.scaleMode = StageScaleMode.NO_SCALE时;
        stage.align = StageAlign.TOP_LEFT;
        stage.nativeWindow.addEventListener（NativeWindowBoundsEvent.RESIZE，windowResizeEventHandler）;
        }

    //窗口resize事件处理函数
    私有函数windowResizeEventHandler（EVT：NativeWindowBoundsEvent）：无效
        {
        evt.currentTarget.width = stage.stageHeight * ASPECT_RATIO;
        }
    }
}
 

解决方案

prevent默认事件，并手动调整窗口大小： 编辑：看来，使空气计算奇怪的是宽度，所以prevent闪烁在一开始设置窗口大小为1050x500的SWF标签

 包{
进口flash.display.Sprite;
进口flash.display.StageAlign;
进口flash.display.StageScaleMode;
进口对象类型：flash.events.Event;
进口flash.events.NativeWindowBoundsEvent;

    //常量
    私有静态常量ASPECT_RATIO：数= 2.0; // 2：1宽高比

    //构造函数
    公共职能airtest（）
    {
        在里面（）;
    }

    //初始化


私有函数的init（）：无效
    {
        在Stage.scaleMode = StageScaleMode.NO_SCALE时;
        stage.align = StageAlign.TOP_LEFT;
        stage.nativeWindow.addEventListener（NativeWindowBoundsEvent.RESIZING，windowResizeEventHandler）;
    }

    私有函数windowResizeEventHandler（EVT：NativeWindowBoundsEvent）：无效
    {
        EVT。preventDefault（）
        如果（evt.beforeBounds.width！= evt.afterBounds.width）{//用户调整宽度
            evt.currentTarget.width = evt.afterBounds.width
            evt.currentTarget.height = evt.afterBounds.width / ASPECT_RATIO;
        }否则，如果（evt.beforeBounds.height！= evt.afterBounds.height）{
            evt.currentTarget.height = evt.afterBounds.height
            evt.currentTarget.width = evt.afterBounds.height * ASPECT_RATIO;
        }

    }
}
}
 

my application launches with the stage size of 1000 x 500, 2:1 aspect ratio. the native window has system chrome, which will always be a little taller by a few pixels.

how is it possible to only permit a native window to resize proportionately in order to always maintain the 2:1 aspect ratio of the stage?

the following code doesn't work as i expect:

package
{
//Imports
import flash.display.NativeWindow;
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.events.Event;
import flash.events.NativeWindowBoundsEvent;

//Class
[SWF(width="1000", height="500", frameRate="60", backgroundColor="#000000")]
public class WindowTest extends Sprite
    {
    //Constants
    private static const ASPECT_RATIO:Number = 2.0; //2:1 Aspect Ratio

    //Constructor
    public function WindowTest()
        {
        init();
        }

    //Initialization
    private function init():void
        {
        stage.scaleMode = StageScaleMode.NO_SCALE;
        stage.align = StageAlign.TOP_LEFT;
        stage.nativeWindow.addEventListener(NativeWindowBoundsEvent.RESIZE, windowResizeEventHandler);
        }

    //Window Resize Event Handler
    private function windowResizeEventHandler(evt:NativeWindowBoundsEvent):void
        {
        evt.currentTarget.width = stage.stageHeight * ASPECT_RATIO;
        }
    }
}

prevent the default event, and resize the window manually: EDIT: it seems, that air is calculating the width in a weird way, so to prevent flickering in the beginning set the window size to 1050x500 in the SWF tag.

package{
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.events.Event;
import flash.events.NativeWindowBoundsEvent;

//Class
[SWF(width="1000", height="500", frameRate="60", backgroundColor="#000000")]
public class airtest extends Sprite
{
    //Constants
    private static const ASPECT_RATIO:Number = 2.0; //2:1 Aspect Ratio

    //Constructor
    public function airtest()
    {
        init();
    }

    //Initialization


private function init():void
    {
        stage.scaleMode = StageScaleMode.NO_SCALE;
        stage.align = StageAlign.TOP_LEFT;
        stage.nativeWindow.addEventListener(NativeWindowBoundsEvent.RESIZING, windowResizeEventHandler);
    }

    private function windowResizeEventHandler(evt:NativeWindowBoundsEvent):void
    {
        evt.preventDefault()
        if (evt.beforeBounds.width != evt.afterBounds.width){//user resizes width
            evt.currentTarget.width = evt.afterBounds.width
            evt.currentTarget.height = evt.afterBounds.width/ASPECT_RATIO;
        } else if (evt.beforeBounds.height != evt.afterBounds.height){
            evt.currentTarget.height = evt.afterBounds.height
            evt.currentTarget.width = evt.afterBounds.height*ASPECT_RATIO;
        }

    }
}
}
