Windows style in Windowbuilder

Hey I coded a calculator. In the design Tab I set it to Windows but wehn I export it, its the nasty "Metal" theme. And it dosnt look like i designed it. Sincerely Jonathan

The Eclipse View

When I export it

The solution is:

First you need to go to: Window > Preferences > WindowBuilder > Swing > LookAndFeel

Then you tick Windows > Apply & Close

public static void main(String[] args) {
    try {
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    } catch(Exception e) {
        System.out.println("Error setting native LAF: " + e);
    }
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                YourFrame frame = new YourFrame();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}
