Is there a look-and-feel-independent way to align a component (e.g. a `JLabel`) horizontally with the *text* of a `JCheckBox`?

I am trying to use values from the `UIDefaults` to predict the location of the text relative to the top-left corner of the `JCheckBox`. I have found a combination that gives the right result for the Metal, Windows, Motif and Aqua Look-and-Feels:  

![Example: Metal (correctly-aligned)](https://i.stack.imgur.com/x4Y0N.png)

But not in Nimbus:

Is there a utility method somewhere that will reliably give X,Y offsets for the text in all Look-and-Feels?

Code (note: to avoid any layout side-effects I used a null layout for this test):

```
import java.awt.Insets;

import javax.swing.JApplet;
import javax.swing.JCheckBox;
import javax.swing.JLabel;
import javax.swing.UIManager;
import javax.swing.border.Border;

public class AlignCheckBoxText extends JApplet {

    public AlignCheckBoxText() {
        setLayout(null);
        checkBox = new JCheckBox("Hello, World!");
        label = new JLabel("Hello, World!");
        add(checkBox);
        add(label);
    }

    @Override
    protected void validateTree() {
        checkBox.setLocation(0, 0);
        checkBox.setSize(checkBox.getPreferredSize());
        int labelX = UIManager.getIcon("CheckBox.icon").getIconWidth();
        Insets cbInsets = UIManager.getInsets("CheckBox.margin");
        if (cbInsets != null) labelX += cbInsets.left + cbInsets.right;
        Border cbBorder = UIManager.getBorder("CheckBox.border");
        if (cbBorder != null) {
            Insets borderInsets = cbBorder.getBorderInsets(checkBox);
            if (borderInsets != null) {
                labelX += borderInsets.left; 
            }
        }
        label.setLocation(labelX, checkBox.getHeight());
        label.setSize(label.getPreferredSize());
        super.validateTree();
    }

    private JCheckBox checkBox;
    private JLabel label;

}

```
