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.
