#813 — setting size of JComboBox

  To: comp.lang.java.gui
Has anyone ever had issues with setting the preferred size of a 
JComboBox using GridBagLayout?  It seems the box's height is larger than 
  the JTextField's height that I create in the same window.  I can 
change the height of the JTextFields by using setPreferredSize() to 
match the JComboBox so everything is uniform but that's only because I 
can't decrease the JComboBox's height because it seems to ignore that 
call.  Any ideas?


thanks
Brandon

Set the fill element on the GridBagConstraints for the JTextField.

Won't that make the JTextField match the size of the JComboBox? I want 
the JComboBox to match the size of the JTextField (JComboBox has the 
larger height due to the button for the dropdown box) which doesn't work 
at the moment because it ignores the setPreferredSize() call.

JComboBoxes have a preferred size that is larger than a JTextField. 
GridBagLayout uses only preferred size, not minimum size.  So if you 
really want to make the JComboBox smaller then you will have to do some 
tricks.  Set the minimum size to 1,1 and reset the preferred size to 
match the height of the JTextField.  I think I would just let my 
JTextField get bigger to match the JComboBox but it does appear to work.

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

public class test extends JFrame {
     String[] array = {"one","two","three"};

     public test() {
         setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         setLayout(new GridBagLayout());

         GridBagConstraints c = new GridBagConstraints();
         c.insets = new Insets(2,2,2,2);

         JComboBox cb = new JComboBox(array);
         JTextField tf = new JTextField("test");

         System.out.println(cb.getMinimumSize());
         System.out.println(cb.getPreferredSize());
         System.out.println(tf.getPreferredSize());

         cb.setMinimumSize(new Dimension(1,1));
         cb.setPreferredSize(new Dimension(cb.getPreferredSize().width,
          tf.getPreferredSize().height));

         add(cb,c);
         add(tf,c);

         pack();
         setVisible(true);

         System.out.println(cb.getSize());
         System.out.println(cb.getPreferredSize());
     }

     public static void main(String[] args) {
         Runnable r = new Runnable() {
             public void run() {
                 new test();
             }
         };
         EventQueue.invokeLater(r);
     }
}

thanks. I got it to work by doing that. I had tried to set the size 
before but couldn't get it to work. I'm not sure what the difference 
between your code and my previous code.  By the way, I was able to leave 
out the setMinimumSize() call.
