Question

I have a Java Swing application, developed on Mac OS X 10.5 using Java 1.5.

I’m trying to make a custom cursor appear when the user moves the mouse over some text in a dialog. The cursor never changes, though.

When I don’t use a JFrame instead of a JDialog, the cursor does change. But then I’ll have to write all the dialog code myself.

How can I get the cursor to appear?

Here’s the simplest code I could create to demonstrate the problem:

import javax.swing.*; import java.awt.*;  public class CursorTest {      public static void main(String[] args) {         JLabel label = new JLabel('Move mouse here for hand cursor');         label.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));         JOptionPane pane = new JOptionPane(label);         pane.setOptions(new Object[]{'OK'});          JDialog dialog = pane.createDialog(null, 'Test Dialog');         dialog.setVisible(true);     } }

Looks like it is a bug in Java 1.5: I first tried with Java 1.6.0_07 and it worked as expected (on Windows XP). Then I recompiled with Java 1.5.0_06 and indeed the cursor remains in default state.

Knowing the difficulties of Java 1.6 on MacOS, I see it will be hard to fix that…

They give a workaround…

[EDIT] Tested workaround:

public class CursorTest extends JFrame {   private CursorTest()   {   }    private void ShowDialog()   {         JLabel label = new JLabel("Move mouse here for hand cursor");         label.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));         JOptionPane pane = new JOptionPane(label);         pane.setOptions(new Object[] { "OK" } );          JDialog dialog = pane.createDialog(this, "Test Dialog");         dialog.setVisible(true);   }    public static void main(String[] args)   {     SwingUtilities.invokeLater(new Runnable()     {       public void run()       {         CursorTest testFrame = new CursorTest();         testFrame.setTitle("Test GUI");         testFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);         testFrame.setSize(500, 300);         testFrame.setVisible(true);         testFrame.ShowDialog();       }     });   } } 

Works fine with my JDK & system.
