Question

Hey I’m attempting to align all panels within a panel to the left of the larger panel.

here is a picture of what I’m currently faced with:

For the master panel (the one that contains all other panels – I shall call it the master!)
I’m using the following code when creating it:

    JPanel panel = new JPanel();
    panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));

For each of the panels within it I’m also using the BoxLayout, but I’ve tried things like [jpanel].setAlignmentX(Component.LEFT_ALIGNMENT) on each panel but that doesn’t seem to work.

Any help would be appreciated!

🙂

edit: for the “Dimensions of box(m):” label, is there any way of aligning that to the top of the panel it’s contained in? It’s in a panel of its own.

edit: Once fixed:

Solution below, thanks all for your help 🙂

You have a number of possibilities, depending on you over all needs.

All I’ve done here is used compound panels and using GridBagLayout to adjust the layouts

public class BadLayout03 {

    public static void main(String[] args) {
        new BadLayout03();
    }

    public BadLayout03() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                JFrame frame = new JFrame();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                frame.add(new MasterPane());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
            }
        });
    }

    public class MasterPane extends JPanel {

        public MasterPane() {
            setLayout(new GridBagLayout());
            GridBagConstraints gbc = new GridBagConstraints();
            gbc.gridx = 0;
            gbc.gridy = 1;
            gbc.weightx = 1;
            gbc.fill = GridBagConstraints.HORIZONTAL;
            gbc.insets = new Insets(4, 4, 4, 4);
            gbc.anchor = GridBagConstraints.WEST;
            add(new DimensionsPane(), gbc);
            gbc.gridy++;
            add(new ColorPane(), gbc);
            gbc.gridy++;
            add(new ReinforementPane(), gbc);
            gbc.gridy++;
