Question

I’ve been trying to Google this answer with no results. I keep on finding answers on how to make Netbeans run in a GTK skin …. this is NOT what I want.

I have a Java Swing application. I can preview it under GTK+, C/X Motif perfectly fine when I right click the JPanel Form –> Preview. However, whenever I try to run the program (build + run), the resulting GUI is a Java Swing look and feel.

How do I permanently enable GTK+ for this program?

Answer 1

You have to set the Look and Feel according to the native look and feel.

The following code must be ran when your app starts up.

public static void setLookAndFeel() {
    try {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    } catch(Exception e) {
      System.out.println("Error setting native LAF: " + e);
    }
}
