Default system look and feel does not work

Hi,
I'm trying to create a simple JFrame with a button on it, but I want this button to look like a native system one.
Here's the code

Code java:

---

package tests;
 
import java.awt.Button;
import javax.swing.JFrame;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
 
public class MyFrame extends JFrame
{
    private Button _button;
 
    public MyFrame() throws ClassNotFoundException, InstantiationException, UnsupportedLookAndFeelException, IllegalAccessException {
        this.setLayout(null);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        _button = new Button("My Button");
        _button.setSize(100, 30);
        _button.setLocation(10, 20);
        this.add(_button);
 
        this.setSize(400, 300);
        this.setVisible(true);
    }
}

But all I get is this:

It doesn't look like a Windows 7 button at all.
What am I doing wrong? :confused:

Why are you using a Button instead of a JButton?

I tried it. It looks like this:

With this code:

Code java:

package differenttests;
 
import java.awt.Point;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
 
 
public class NativeLooks extends JFrame
{
    public NativeLooks() throws ClassNotFoundException, InstantiationException,
                                IllegalAccessException, UnsupportedLookAndFeelException {
        this.setDefaultCloseOperation(3);
        this.setLayout(null);
 
        JButton button = new JButton("Click");
        button.setSize(100, 30);
        button.setLocation(new Point(10, 10));
        this.add(button);
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
 
        this.setSize(320, 240);
        this.setVisible(true);
    }
}

I found what the problem was. Such a stupid blunder of mine :D
I had to set up look and feel before creating a button:

Code java:

---

package differenttests;
 
import java.awt.Point;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
 
 
public class NativeLooks extends JFrame
{
    public NativeLooks() throws ClassNotFoundException, InstantiationException,
                                IllegalAccessException, UnsupportedLookAndFeelException {
        this.setDefaultCloseOperation(3);
        this.setLayout(null);
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
 
        JButton button = new JButton("Click");
        button.setSize(100, 30);
        button.setLocation(new Point(10, 10));
        this.add(button);
        this.setSize(320, 240);
        this.setVisible(true);
    }
}

Now the button looks like it's supposed to :)
