我对 JDialog 有一些问题。我在 NetBeans 中创建了 Swing GUI。GUI 包含带有按钮、文本字段等的主框架。当我单击“下一步”按钮时，会显示 JDialog（在 NetBeans 中也创建，其他组件部分）。以下是此 JDialog 的自定义属性：
- 模态=真；
- 可调整大小 = 假；
- 默认关闭操作 = DISPOSE
问题是，在 Windows XP（也可能是 7）上，当 JDialog 发生时，我无法通过最小化父表单来最小化应用程序。在 Ubuntu 上它按预期工作，但在 Windows 上却没有。
我查看了http://docs.oracle.com/javase/tutorial/uiswing/misc/modality.html ，这个例子也在 Ubuntu 和 Widows 上运行。因此，我尝试在演示中手动创建示例 JDialog。再次在 Ubuntu 上是 woking，在 Windows 上不是。
有人有什么想法吗？我还没有。
SAmple DEMO，适用于 Ubuntu，不适用于 Windows XP：
