Java JOptionPane光标

使用JOprionPane时，光标出现了一些问题。我将光标设置到pharent框架，然后使用以下命令显示对话框：

Object[] possibilities = {"ham", "spam", "yam"};
String s = (String) JOptionPane.showInputDialog(MagicCollectorClient.getMainFrame(),"Complete the sentence:\n\"Green eggs and...\"",
            "Customized Dialog",JOptionPane.PLAIN_MESSAGE,null,possibilities,"ham");

它显示对话框，但将光标更改为默认系统光标，直到关闭对话框。有什么办法可以解决这个问题吗？

用一台电脑怎么样？是的，这是可能的，您必须将JOptionPane从静态方法助手中“解除绑定”，因为您希望对它做一些特殊的处理。不幸的是，这意味着你还有一点工作要做，但没有什么太可怕的

public static void main(String[] args) {
    JFrame parent = new JFrame();
    parent.setSize(400, 400);
    parent.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
    parent.setVisible(true);

    Object[] possibilities = { "ham", "spam", "yam" };

    // raw pane
    JOptionPane optionPane = new JOptionPane(
            "Complete the sentence:\n\"Green eggs and...\"",
            JOptionPane.PLAIN_MESSAGE, JOptionPane.DEFAULT_OPTION, null,
            possibilities, possibilities[0]);

    // create a dialog for it with the title
    JDialog dialog = optionPane.createDialog("Customized Dialog");

    // special code - in this case make the cursors match
    dialog.setCursor(parent.getCursor());

    // show it
    dialog.setVisible(true);

    // blocking call, gets the selection
    String s = (String) optionPane.getValue();

    System.out.println("Selected " + s);
}
