#2728 — Justifying box components

  To: comp.lang.java.gui
I want to put a JSlider underneath a label explaining what it is there
for. I have used a Box object instantiated with the createVerticalBox
constructor. The problem is that the text and the slider has a bad
alignment. Is there any way to make them both centered or justified to
either side of the column? Thanks in advance.

I haven't played with BoxLayout much but what you want to do is really 
easy with GridBagLayout.

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

public class test  {
     public static void main(String[] args) {
         Runnable r = new Runnable() {
             public void run() {
                 JFrame f = new JFrame("test");
                 f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                 f.setLayout(new GridBagLayout());
                 GridBagConstraints c = new GridBagConstraints();
                 c.gridy = 0;  c.insets = new Insets(2,2,2,2);
                 c.anchor = GridBagConstraints.CENTER;

                 JLabel l = new JLabel("JSlider Info");
                 f.add(l,c);

                 ++c.gridy;
                 JSlider s = new JSlider(0,100,50);
                 f.add(s,c);

                 f.setSize(400,300);
                 f.setVisible(true);
             }
         };
         EventQueue.invokeLater(r);
     }
}

if the label is off to the right a bit, add this line
slider.setAlignmentX(0);
but it still might not suit, as the label will appear a bit left of the start of the slider track

if you want them centered, add both lines
slider.setAlignmentX(.5f);
label.setAlignmentX(.5f);

There are some constants that I find handy for this:
   slider.setAlignmentX(Component.CENTER_ALIGNMENT);
   label.setAlignmentX(Component.CENTER_ALIGNMENT);

If I need to justify a large number of components, I use a for loop:
   for(JComponent c: new JComponent[]
           { slider, label, this, that, other })
       c.setAlignmentX(Component.CENTER_ALIGNMENT);
