我目前正在使用此代码创建JDialog；

import javax.swing.UIManager;
public class SheetDialog {
private JFrame _windowFrame;
public static void main(String[] args) {
System.setProperty("apple.awt.documentModalSheet", "true");
System.setProperty("apple.awt.brushMetalLook", "true");
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
new SheetDialog();
} catch (Exception e) {
e.printStackTrace();
}
}
public SheetDialog() {
_windowFrame = new JFrame();
_windowFrame.setResizable(false);
_windowFrame.setBounds(100, 100, 451, 320);
_windowFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
_windowFrame.getContentPane().setLayout(null);
_windowFrame.setVisible(true);
JButton showDialogButton = new JButton("Show Dialog");
showDialogButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
showSheetDialog(_windowFrame, "Test", "This should be a sheet dialog", "Oke");
}
});
showDialogButton.setBounds(328, 263, 117, 29);
_windowFrame.getContentPane().add(showDialogButton);
}
public void showSheetDialog(JFrame owner, String title, String message, String button) {
final JDialog messageDialog = new JDialog(owner, title, Dialog.ModalityType.DOCUMENT_MODAL);
messageDialog.setBounds(30, 0, owner.getWidth() - 60, 130);
// TODO: only when os is osx
messageDialog.getRootPane().putClientProperty("apple.awt.documentModalSheet", "true");
messageDialog.setLayout(null);
int offsetX = 25;
JLabel titleLabel = new JLabel(title);
titleLabel.setFont(new Font("Lucida Grande", Font.BOLD, 13));
titleLabel.setBounds(offsetX, 10, 100, 25);
messageDialog.getContentPane().add(titleLabel);
JLabel messageLabel = new JLabel(message);
messageLabel.setVerticalTextPosition(JLabel.TOP);
messageLabel.setHorizontalTextPosition(JLabel.LEFT);
messageLabel.setFont(new Font("Lucida Grande", Font.PLAIN, 11));

我以前使用Java 6来编译应用程序并设置clientProperty apple.awt.documentModalSheet可以完美地在OSX上将对话框显示为“ Sheet”，但现在我开始使用Java 7（更新25），并且不再使用该对话框显示为表格。我似乎找不到任何更新文档。他们对此有什么改变吗？我该如何解决？使用工作表，当前的界面设计要好于对话框。
更新
我发现了以下错误报告，似乎与我遇到的问题相同；
http://bugs.sun.com/view_bug.do?bug_id=8010197
有人知道如何解决此问题吗？我已经研究了QuaQua之类的库，但是我不希望使用任何库，因为我只想要工作表功能。
更新2
我尝试过QuaQua，但是使用Java 7编译时，库当前存在完全相同的问题。任何解决方法？
更新3
用工作示例替换的代码（http://pastebin.com/PJ8VGdPb）
更新4
[发现SWT的Shell类具有一种名为SWT.SHEET的样式，该样式仍可在Java7中使用，我不喜欢使用SWT之类的库，但这似乎是唯一的解决方案。
据我所知，Apple尚未正式发布其JDK 7版本。Apple已为其OS X优化的最新JDK版本仍为JDK6。这也是Java的更新来自AppStore更新的原因。标签。这些更新并非直接来自Oracle。
如果直接从Oracle下载JDK 7，这是一个更通用的，未经调整的版本。
所以，我认为您只需要等待苹果发布其OS X优化的JDK 7。
从Oracle下载时，我经历了许多OS X功能无法正常工作：
似乎在JDK修复bug之前，您必须自己实现Sheet。
关键点是：

这是我想到的一个超级狡猾的骇客，它设置了JDK现在似乎忘记设置并手动将窗口放置在正确位置的标志。虽然仍然缺少阴影，所以我想知道是否有人可以对此进行改进。 ;）
这与内部类和私有字段混淆，因此它可能会在任何给定的JDK新发行版中中断，但仍适用于8u5。也许它将为这些内部AWT类的结构提供一些见识。

// can't work for those. :(
if (peer instanceof LWWindowPeer) {
LWWindowPeer windowPeer = (LWWindowPeer) dialog.getPeer();
//XXX: Should check this before casting too.
CPlatformWindow platformWindow = (CPlatformWindow) windowPeer.getPlatformWindow();
try {
Method method = CPlatformWindow.class.getDeclaredMethod(
"setStyleBits", int.class, boolean.class);
