Make the checkbox on a mult-line JCheckbox align with the first line, not the center
Question
I am running a program that adds multiple different JCheckBoxes to a GroupLayout JPanel on a JFrame and I've hit a slight problem. With the following code the program will successfully make a multi-line JCheckBox, but the checkbox vertically aligns in the center of the 4 lines and I want it to align with the first line:
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import java.io.*;
import javax.swing.*;
import javax.swing.JCheckBox;
import javax.swing.GroupLayout;
public class MainClass {
public static void main(String[] args) {
JFrame f = new JFrame("Survey");
JPanel p = new JPanel();
GroupLayout layout = new GroupLayout(p);
GroupLayout.SequentialGroup hGroup = layout.createSequentialGroup();
GroupLayout.SequentialGroup vGroup = layout.createSequentialGroup();
p.setLayout(layout);
JCheckBox example = new JCheckBox();
example.setText("<html><body>lorum ipsum lorum ipsum lorum ipsum lorum ipsum lorum ipsum");
hGroup.addComponent(example, 0,150,150);
vGroup.addComponent(example);
layout.setHorizontalGroup(hGroup);
layout.setVerticalGroup(vGroup);
f.add(p);
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLocationRelativeTo(null);
f.setVisible(true);
f.setExtendedState(f.getExtendedState() | JFrame.MAXIMIZED_BOTH);
}
}
Output:
I want it to look like this (Mind my terrible image editing skills and the fact that its randomly a different shade of grey):
As you can see I use GroupLayout, if possible I would like to retain this because I want to apply this to a much larger program and restructuring my entire layout is less than ideal. Thanks

Take a look at the AbstractButton API.
There are several methods that allow you to control the location of the text relative to the icon.
For example:
JCheckBox example = new JCheckBox();
example.setText("<html><body>lorum ipsum lorum ipsum lorum ipsum lorum ipsum lorum ipsum");
example.setVerticalTextPosition(SwingConstants.TOP);
