Look and Feel doesn't work.

Okay, i'm currently programming a java game and atm i am making a Game Launcher for it. I'm trying to make the Gui look better cause atm it's just ugly. Here's the code that matters.

import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

import javax.swing.*;

public class main extends JFrame{
	
	main(){
//Removed this code as it doesn't matter. It's jsut the placement of all of the buttons and whatnot.
setLayout(null);
	}
	
	public static void main(String args[]){
		main gui = new main();
		try{
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
    }
    catch(Exception e){
            System.out.println("Nimbus isn't available");
    }
		gui.setTitle("Launcher");
		gui.setVisible(true);
		gui.setLocationRelativeTo(null);
		gui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		gui.setSize(600, 400);
		gui.setResizable(false);
	}

Now i have already been through this issue before. It has something to do with the setLayout(null); part.
There is some code i used to have that somehow fixed this. it was something like "UIManager.updatetool" or something like that... Any help?

Here's an image of my current launcher.

As you can see, the JButtons and JTextFields are NOT using the Nimbus layout.

I am no expert on L&F, but I believe that you must set it *before* you create any GUI components. So consider swapping the two lines indicated below.

    public static void main(String args[]){
        // swap the line of code below
        main gui = new main();

        // with this block of code
        try{
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
        } catch (....) {
           ....
        }

Also, you really should avoid all use of the null layout.

I already tried placing it there, and why not use setLayout null?

I already tried placing it there...

So you have tried calling the set look and feel as the very first part of the main method? And this didn't work? If so, please double check.

..., and why not use setLayout null?

For many reasons including

• The GUI will look better on multiple platforms
• Decrease the risk of layout bugs
• Make your GUI *much* easier to maintain and upgrade.

Okay i know for sure that i've tried that before, but i tried it again just to make sure and for some reason it works now. Thanks =D

Try using.

UIManager.setLookAndFeel("javax.swing.plaf.nimbus. NimbusLookAndFeel");

This will definitely work if you have Java 1.7 or higher.

The better, version-independent way of attempting to use the Nimbus LaF is explained in the Tutorial: Nimbus Look and Feel (The Java™ Tutorials > Creating a GUI With JFC/Swing > Modifying the Look and Feel)
