当设置外观时，JOptionPane不起作用

Question

I set below look and feel for main class.

Base class code:

 static
{
    try
    {
        UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
    }
    catch (Exception exception)
    {
        logger.error("Error setting look and feel!", exception);
    }
}

Sub class code:

   int result = JOptionPane.showOptionDialog(panel,
            message,
            "",
            JOptionPane.YES_NO_CANCEL_OPTION,
            JOptionPane.QUESTION_MESSAGE,
            null,
            formattedOptions,
            formattedOptions[0]);

The windows look and feel is not get set as windows for JOptionPane rather it's showing java default look and feel.

Could you please help me out?

This is most likely timing related. Try setting laf using vm arg:

-Dswing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel
