The OpenJDK version in Debian includes the GTK+ theme, but the
SystemLookAndFeelClassName is set to the default Swing Metal theme.
Manually loading the GTK+ theme works, but this is very unportable and
shouldn't be necessary.
Instead, the following code should use the native GTK+ theme:
import java.awt.*;
import javax.swing.*;
public class Test {
public static void main(String[] args) {
try {
System.out.println("System look&feel class: " +
UIManager.getSystemLookAndFeelClassName());
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
// This shouldn't be necessary:
//
UIManager.setLookAndFeel("com.sun.java.swing.plaf.gtk.GTKLookAndFeel");
} catch (Exception e) {
System.err.println("Can't find native look&feel: " + e);
}
JFrame frame = new JFrame();
frame.getContentPane().setLayout(new FlowLayout());
frame.setSize(new Dimension(200, 200));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(new JButton("Button 1"));
frame.getContentPane().add(new JButton("Button 2"));
frame.getContentPane().add(new JButton("Button 3"));
frame.setVisible(true);
}
}
Is this by design, or would it be possible to change the system theme to the
native one?
Metal doesn't really fit well with most modern desktops, and the GTK+ theme
would at least make Java applications match the system GTK theme.
