the JVM determines component spacing and sizing at runtime. It's pretty much out of your hands.

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

You mean to say I have no control over the display
Then how do I do this?

Jwenting just said "It's pretty much out of your hands."

I don't see what the problem is, how it looks is just pointless fluff. If it works it works. What more do you want.

you have absolute control over the way the components are displayed in relation to each other.
You have very little control over how (what size and visual style) they're displayed at.

This is deliberate to enable the JVM to make it look decent on different operating systems that have different ways of doing things.
If you go and set that an input control is X pixels by Y pixels with a border of Z pixels that may look great on your Windows machine but completely crappy on a Mac or X terminal.
It may even be impossible to render there at all at that size.

Greetings:
You could try with GridBagLayout, it allows you to control a little more the appereance by using weights for the spaces that the components use, something like this:

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
GridBagLayout gridbag = new GridBagLayout();
this.getContentPane().setLayout(gridbag);
GridBagConstraints c = new GridBagConstraints();
c.fill = GridBagConstraints.BOTH;
//to add components you just asign a grid position and a weight
g.gridx=0;c.gridy=0;c.weightx=2;c.weighty=0;this.getContentPane().add(component,c);
GridBagLayout gridbag = new GridBagLayout();
this.getContentPane().setLayout(gridbag);
GridBagConstraints c = new GridBagConstraints();
c.fill = GridBagConstraints.BOTH;
//to add components you just asign a grid position and a weight
g.gridx=0;c.gridy=0;c.weightx=2;c.weighty=0;this.getContentPane().add(component,c);

Here is the description of GridbagLayout from java.sun, http://java.sun.com/docs/books/tutor...t/gridbag.html

You could always set the layout to null and set the bounds, but I don't know if that's a good idea or not...... That is, if you are talking about positioning components.
