Usage

From source file:Main.java

public static void main(String[] args) {
    SpringLayout layout = new SpringLayout();
    JPanel p = new JPanel(layout);
    p.setBorder(BorderFactory.createLineBorder(Color.GREEN, 10));

    JLabel l1 = new JLabel("label: width=90%", SwingConstants.CENTER);
    l1.setBorder(BorderFactory.createLineBorder(Color.RED, 1));
    JButton l2 = new JButton("button: width=50%");

    Spring panelw = layout.getConstraint(WIDTH, p);

    SpringLayout.Constraints c1 = layout.getConstraints(l1);
    c1.setX(Spring.constant(0));//ww  w. j  av a 2  s .c om
    c1.setY(Spring.constant(20));
    c1.setWidth(Spring.scale(panelw, 0.9f));
    p.add(l1);

    SpringLayout.Constraints c2 = layout.getConstraints(l2);
    c2.setWidth(Spring.scale(panelw, 0.5f));
    layout.putConstraint(SOUTH, l2, -20, SOUTH, p);
    layout.putConstraint(EAST, l2, -20, EAST, p);
    p.add(l2);

    f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    f.getContentPane().add(p);
