Swing L&F - Import and implementation

Question

I built a game on java and now I want to make it looks better, I used the default "Nimbus" LookAndFeel but it's just not good enough. I tried install some other themes by building the .jar files into class path but it didn't work all the times I tried it showed all kinds of messages, so maybe I'm doing something wrong. I would be grateful if someone will explain to me how to make that work!

Answer 1

You can do in this way. Add to the classpath the theme you want. Search and copy the qualified name and, finally, this:

    try {
        UIManager.setLookAndFeel("javax.swing.plaf.nimbus.NimbusLookAndFeel");
        //UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        //UIManager.setLookAndFeel("set.qualified.name.here");
    } catch (ClassNotFoundException | InstantiationException
            | IllegalAccessException | UnsupportedLookAndFeelException e) {
        e.printStackTrace();
    }

Answer 2

import javax.swing.UIManager;

public class MainClass {
  public static void main(String[] a) {
    UIManager.LookAndFeelInfo[] looks = UIManager.getInstalledLookAndFeels();
    for (UIManager.LookAndFeelInfo look : looks) {
      System.out.println(look.getClassName());
    }
  }
}

will list all the available look and feel. check what you like most. you can also check some really amazing l&f from http://www.jwrapper.com/blog/6-great-look-and-feels-to-make-your-java-app-pretty
