Group layout three elements in a row

Question

Here is how i add elements in layout

GroupLayout layout = new GroupLayout(panel);
    layout.setAutoCreateGaps(true);
    layout.setAutoCreateContainerGaps(true);
    panel.setLayout(layout);

    layout.setHorizontalGroup(
        layout.createSequentialGroup()
            .addGroup(layout.createParallelGroup(GroupLayout.Alignment.TRAILING))
                .addComponent(socSecIconLabel)
                .addComponent(creditCardIconLabel)
            .addGroup(layout.createParallelGroup(GroupLayout.Alignment.TRAILING))
                .addComponent(socSecLabel)
                .addComponent(creditCardLabel)
            .addGroup(layout.createParallelGroup(GroupLayout.Alignment.LEADING))
                .addComponent(socSecCheck)
                .addComponent(creditCardCheck)
    );

    layout.setVerticalGroup(
        layout.createSequentialGroup()
            .addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE))
                .addComponent(socSecIconLabel)
                .addComponent(socSecLabel)
                .addComponent(socSecCheck)
            .addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE))
                .addComponent(creditCardIconLabel)
                .addComponent(creditCardLabel)
                .addComponent(creditCardCheck)
    );

My goal is icon label::label::checkbox in each row, but with this code i get only mess:

How to align elements in each row?

Don't use GroupLayout. It is probably the most complicated layout manager and is generally only used by IDE's for generated code. If you want components in a row you can use a FlowLayout, or a BoxLayout or a GridBagLayout. You can also nest panels with different layout manager to achieve your desired layout. Read the section from the Swing tutorial on [Layout Managers](https://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html) for more information and working examples. I would suggest the GridBagLayout is probably what you want in this case. — camickr, Mar 13 '18 at 16:06

As I suggested use a `GridBagLayout`. You have the tutorial link. Read the tutorial, download the demo code and make changes. If you still want to use the GroupLayout well, the tutorial also has a demo for that and you can download and change the demo code. — camickr, Mar 14 '18 at 15:00

Here is an example that uses GridLayout, two rows and four columns:

import java.awt.*;
import javax.swing.*;

public class GridLayoutExample extends JFrame {

    public void addComponents(final Container pane) {
        JPanel panel = new JPanel();
        panel.setLayout(new GridLayout(2,4)); //2 rows, 4 columns

        panel.add(new JLabel("Social security"));
        panel.add(new JButton("Click 1"));
        panel.add(new JCheckBox(""));
        panel.add(new JTextField());

        panel.add(new JLabel("Credit card"));
        panel.add(new JButton("Click 2"));
        panel.add(new JCheckBox(""));
        panel.add(new JTextField());

        pane.add(panel);
    }

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                GridLayoutExample frame = new GridLayoutExample();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.addComponents(frame.getContentPane());
                frame.pack();
                frame.setVisible(true);
            }
        });
    }
}

You have the right idea, but I think the problem is the extra ) at the end of each addGroup. Instead of

.addGroup(layout.createParallelGroup(GroupLayout.Alignment.TRAILING))
            .addComponent(socSecIconLabel)

try

.addGroup(layout.createParallelGroup(GroupLayout.Alignment.TRAILING)
            .addComponent(socSecIconLabel)

Your code is adding the components to the "generic" group instead of the specific parallel group that you created.
