Question

In Netbeans 7.2 when I type in setLookAndFeel(); it says the method isn’t found. What did I do wrong?

import javax.swing.*;

public class SalutonFrame extends JFrame  {

    public SalutonFrame() throws UnsupportedLookAndFeelException {
        super("Saluton Mondo!");

        setLookAndFeel();

        setSize(350, 100);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

Answer 1

To set the look and feel of a frame, you must do it before the constructor, via the UIManager. You can do it like so:

    UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
    JFrame someFrame = new JFrame();

or whatever class your look and feel you want to use is instead of the basic Java look shown in the example. See here for more info.
