Java JScrollPane不'；t使用本机操作系统滚动（Swing）

我在Windows8.1操作系统上制作了一个小的

JDialog

，其中包含一个JScrollPane和一些其他组件。 问题是，滚动窗格的滚动有点奇怪。。。不是本机Windows 8.1滚动条：

我尝试使用

外观和感觉功能作为休闲：

    try {
        UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
    } catch (Exception e) {
        // Handle exception
    }

这根本没用

那么，我是不是用错了，或者有没有其他方法来使用本机操作系统的滚动条

此外，如果有人能解释如何定制卷轴（如箭头图片，或定制轨道和旋钮），我将不胜感激

编辑这是提到的JDialog的代码，说明iis存在问题：

你已经向我们展示了你的尝试，但不是当它被调用时。通常，您会在创建任何组件之前设置L&F，但我们无法仅通过这个小片段看到这一点。请发布一个演示问题的示例。Swing不使用本机控件，它模拟这些控件。您需要使用不同的UI库才能获得真正的本机控件。如果希望Swing应用程序看起来像本机应用程序，则需要使用系统外观，而不是跨平台外观<代码>UIManager.setLookAndFeel（UIManager.getSystemLookAndFeelClassName（））

另外，对于定制，请参阅本文以了解总体思路：谢谢@a_horse_和_no_name！！它起作用了！谢谢你，我会留意的。
