A DESCRIPTION OF THE PROBLEM :
Looks GOOD on JDK 17
<link>
Looks BAD on JDK 19:
<llink>
The issue seems to be specific to (1) macOS system LaF and (2) using HTML as button text and (3) using setHorizontalAlignment(LEFT) which in combination leads to icon / text / button border not aligning correctly.
REGRESSION : Last worked in version 17.0.6
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Please run the self-contained test case below on macOS with JDK 17 and JDK 19 and you will find that that JDK 19 does not render the icon in the correct location.
---------- BEGIN SOURCE ----------
package test;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Component;
import java.awt.Graphics;
import javax.swing.Icon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
public class Main {
public static void main(String[] args) throws Exception {
SwingUtilities.invokeLater(() -> {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
e.printStackTrace();
}
JButton button = new JButton("<html><nobr><u>Test</u></nobr></html>", new TestIcon());
button.setHorizontalAlignment(JButton.LEFT);
JFrame window = new JFrame();
window.getContentPane().add(button, BorderLayout.CENTER);
window.pack();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setVisible(true);
});
}
public static class TestIcon implements Icon {
@Override
public void paintIcon(Component c, Graphics g, int x, int y) {
g.setColor(Color.MAGENTA);
g.fillRect(x, y, 16, 16);
}
@Override
public int getIconWidth() {
return 16;
}
@Override
public int getIconHeight() {
return 16;
}
}
}
---------- END SOURCE ----------
CUSTOMER SUBMITTED WORKAROUND :
Use JDK 17 instead of JDK 19.
FREQUENCY : always
