MigLayout

Wrapping elements

This example demonstrates how to place 3 buttons in total with 2 buttons being in the first row. Then a wrap occurs, so the last button is in a new row.

The constraints are simple strings, in this case “wrap” while placing the component.

public class ShowMigLayout {

    // Create the elements
    private final JFrame demo = new JFrame();
    private final JPanel panel = new JPanel();
    private final JButton button1 = new JButton("First Button");
    private final JButton button2 = new JButton("Second Button");
    private final JButton button3 = new JButton("Third Button");

    public static void main(String[] args) {
        ShowMigLayout showMigLayout = new ShowMigLayout();
        SwingUtilities.invokeLater(showMigLayout::createAndShowGui);
    }

    public void createAndShowGui() {
        // Set the position and the size of the frame
        demo.setBounds(400, 400, 250, 120);

        // Tell the panel to use the MigLayout as layout manager
        panel.setLayout(new MigLayout());

        panel.add(button1);
        // Notice the wrapping
        panel.add(button2, "wrap");
        panel.add(button3);

        demo.add(panel);
        demo.setVisible(true);
    }
}
