I'm trying to make a custom JTextField that hosts a JLabel, So I have wrapped the JTextField and the JLabel in a custom Class that extends JPanel

The JPanel layout is set to GridBagLayout since I only need place 2 components vertically. Here is how it looks like

This is the code, I can't spot where I have instructed the GridBagLayout to center the JLabel.

setLayout(new GridBagLayout());

jLabel = new JLabel();

GridBagConstraints gbc = new GridBagConstraints();

gbc.fill = GridBagConstraints.VERTICAL;

gbc.gridy = 1;

add(jLabel, gbc);

I want to have the JLabel the same position at shown in the GIF. How can I achieve this? Would also be nice if anyone can point what the exact text size would look good on the JLabel.

the JLabel does not start from line start, nor is it center. It's kinda in between

I'm not sure what your exact code is and how you nest the custom panel in another panel.

But as I mentioned above when you have weird alignment you need to make sure each component has the same x alignment so they can be aligned the same way.

I can't reproduce your problem using the simple example below:

import java.awt.*;

import javax.swing.*;

import javax.swing.border.*;



public class SSCCE extends JPanel

{

    SSCCE()

    {

        JPanel box = new JPanel();

        box.setLayout( new BoxLayout(box, BoxLayout.Y_AXIS) );

        box.setBorder( new LineBorder(Color.RED) );



        JTextField textField = new JTextField(10);

        //textField.setAlignmentX(JComponent.LEFT_ALIGNMENT);

        System.out.println( textField.getAlignmentX() );

        box.add( textField );





        JLabel label = new JLabel("Some text");

        System.out.println( label.getAlignmentX() );

        box.add( label );



        add( box );

    }



    private static void createAndShowGUI()

    {

        JFrame frame = new JFrame("SSCCE");

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.add(new SSCCE());

        frame.pack();

        frame.setLocationByPlatform( true );

        frame.setVisible( true );

    }



    public static void main(String args) throws Exception

    {

        java.awt.EventQueue.invokeLater( () -> createAndShowGUI() );

/*

        EventQueue.invokeLater(new Runnable()

        {

            public void run()

            {

                createAndShowGUI();

            }

        });

*/

    }

}

But as you can see from the output by default a text field has center alignment and the label left alignment. Try making them both left aligned.

Thanks to VGR in the comments, I have solved this issue by setting the anchor to LINE_STARTS

gbc.anchor = GridBagConstraints.LINE_STARTS;

Edit: Ended up using BoxLayout thanks to camickr for answering with an example.
