在Java 6和Java 7使用透明窗口(Using transparent window in b

我在开发应用程序Java 6 ，其使用透明（1.6.0_24） JFrame获得消失动画。 这里是我的代码：

public static void slowDisappearWindowAction(Window source, int milisSlow, int milisFast) throws InterruptedException{
    float level = 1.0f;
    //slow effect -> 50%
    for(int i=0; i<8 ; i++){
        level=level-0.05f;
        AWTUtilities.setWindowOpacity(source,level);
        Thread.sleep(milisSlow);
    }
    //fast effect -> 0% 
    for(int i=0; i<8 ; i++){
        level=level-0.05f;
        AWTUtilities.setWindowOpacity(source,level);
        Thread.sleep(milisFast);
    }
    AWTUtilities.setWindowOpacity(source,0.1f);
}

它工作正常，我的机器上，但是当我测试它与另一台PC上Java 7安装我已经撂荒错误：

我想，这是因为在Java 7 ，我应该使用Window.setOpacity(...)而不是AWTUtilities方法。

它是可以使用的透明度在Java 6的应用程序，将上运行Java 7 ？

Answer 1:

请参阅如何创建透明和不规则窗口 。它提到了“每个像素”半透明，你可以利用，使与具有从Java 6的半透明窗口，它不再可用的外观和感觉的Java 7的窗口。 所以基本上你不得不代码，使其适合，或者你可以用一个“统一的透明度”，这与两个工作去了。
