SpringLayout

SpringLayout allows you to attach "springs" to components. Components are laid out relative to other components. Each component added to the container can have an attached SpringLayout.Constraints. import java.awt.Component; import java.awt.Container; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextField; import javax.swing.SpringLayout; public class SpringSample {   public static void main(String args[]) {     JFrame frame = new JFrame("SpringLayout");     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     Container contentPane = frame.getContentPane();     SpringLayout layout = new SpringLayout();     contentPane.setLayout(layout);     Component left = new JLabel("Left");     Component right = new JTextField(15);     contentPane.add(left);     contentPane.add(right);     layout.putConstraint(SpringLayout.WEST, left, 10, SpringLayout.WEST, contentPane);     layout.putConstraint(SpringLayout.NORTH, left, 25, SpringLayout.NORTH, contentPane);     layout.putConstraint(SpringLayout.NORTH, right, 25, SpringLayout.NORTH, contentPane);     layout.putConstraint(SpringLayout.WEST, right, 20, SpringLayout.EAST, left);     frame.setSize(300, 100);     frame.setVisible(true);   } }
