Hello,

I have a JPanel subclass with swing components on it. I don't manage to 
put the button at the left of the panel. Why ?

Here is a simplified version of the source code:

=========================== >8 =====
package java_;

import java.awt.EventQueue;

import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class TestGroupLayout extends JPanel {

   public TestGroupLayout() {
     init();
   }

   private void init() {
         jLabel1 = new javax.swing.JLabel("l1");
         combo1 = new javax.swing.JComboBox();
         jLabel2 = new javax.swing.JLabel("l2");
         combo2 = new javax.swing.JComboBox();
         jLabel3 = new javax.swing.JLabel("l3");
         spinner = new javax.swing.JSpinner();
         check = new JCheckBox("check");
         button = new JButton("bouton");

         org.jdesktop.layout.GroupLayout layout = new

To the OP.  hiwa's reply made me think of something
I considered mentioning when I first saw those same 
compile errors (..heck, it is much quicker to compile 
code and see errors, than read it and try and guess).
That is..
Perhaps there is a more specific forum for enquiring
about problems with GroupLayout.  As you can see,
it is not commonly used 'about these parts'.

Doesn't the JDesktop site have forums for the API's?
Maybe you'd have better luck on those.

Hi AT, nice to meet you.
I think the OP should have used javax.swing.GroupLayout from the start
because it is better than jdesktop one in design, implementation, and
among other things, documentation. The jdesktop one is hard to use
because of poor documentation.

Are you not *the* hiwa that hosts the algafield

In that case, I would have expected that statement to be..
"Hi AT, nice to meet you again."  ..or..
Hi AT, nice to talk to you again.

Oh, ..and nice talking to you, whether you're the 
hiwa I have known for a long time, or another 
person with same name!

>I think the OP should have used javax.swing.GroupLayout

(checks 1.6 docs.)  GroupLayout.. right.  Actually it was
the first time I had noticed it!  Thanks for the heads up.  :-)

Uh-huhh.  I've used neither, so I'll take your word for it.

But - good idea.  I tried changing the imports directly
to the javax.swing.GroupLayout and LayoutStyle, but
the code required changes beyond that, before it would
compile.

OP - try it with the 1.6 Swing class, and get back to
us with an SSCCE if you cannot sort the problem (is
what I recommend).

Yes, I am the man who translates cljg GUI FAQ in Japanese. :)
The below code needs some more elaboration but I think you could get
the basic idea for using Groups both for x-direction and y-direction.
Using both direction is the MUST for the GroupLayout.
-------------------------------------------------------------

    jLabel1 = new javax.swing.JLabel("l1");
    combo1 = new javax.swing.JComboBox();
    jLabel2 = new javax.swing.JLabel("l2");
    combo2 = new javax.swing.JComboBox();
    jLabel3 = new javax.swing.JLabel("l3");
    spinner = new javax.swing.JSpinner();
    check = new JCheckBox("check");
    button = new JButton("bouton");

    org.jdesktop.layout.GroupLayout layout = new
      org.jdesktop.layout.GroupLayout(this);
    this.setLayout(layout);

    org.jdesktop.layout.GroupLayout.SequentialGroup hGroup
      = layout.createSequentialGroup();
 
hGroup.add(layout.createParallelGroup().add(check).add(jLabel1).add(jLabel2).add(jLabel3).add(button)).
 
add(layout.createParallelGroup().add(combo1).add(combo2).add(spinner));
    layout.setHorizontalGroup(hGroup);

    org.jdesktop.layout.GroupLayout.SequentialGroup vGroup =
layout.createSequentialGroup();
 
vGroup.add(layout.createParallelGroup(org.jdesktop.layout.GroupLayout.BASELINE).add(check)).

add(layout.createParallelGroup(org.jdesktop.layout.GroupLayout.BASELINE).add(button));
    layout.setVerticalGroup(vGroup);
  }

(chuckles) I hate to admit this, but despite knowing

you as a 'man' rather than simply a 'person'!

I had always been very careful to refer to you as 
'hiwa' or 'the last poster' or using other, non gender 
specific references to you, or things you wrote.

Of course, it is always a good idea to not jump to 
conclusions, and refer to people generically.  
After all, it is all about *what* they say, rather 
than *who* (other people might think) they are*.

Hope the OP has more luck with your code..

Yes. I hate the word 'man' but I couldn't think of the word 'person'
then. Now I regret that.

Below is an improved version of the GroupLayout test program in which
we add not only components but group of groups on the main layout
group. I think this is the powerfull feature of the new layout
manager.
-----------------------------------------------

     * button */

    /* horizontally, only one loc, but there's a subgroup above */
    org.jdesktop.layout.GroupLayout.SequentialGroup hGroup
      = layout.createSequentialGroup();
    // use group of groups created above to place on a same X loc

The lib is https://swing-layout.dev.java.net/ . I thought it was common 
enough, sorry.

The 2 example you gave changes a lot of things from what i posted. The 
margin are removed, the spinner and the combo are way too big...

I'm gonna try to extract what is needed just to have the button left 
aligned. I hope it can be done.

Thanks for your help

It was a bad parenthesis !!!!!!!!!!!!!!!!

		SequentialGroup gh1 = layout.createSequentialGroup()
		.add(jLabel1)
		.addPreferredGap(LayoutStyle.RELATED)
