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:

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.
