JDev 11g Extension Preferences Panel

Question

Hi,
I'm designing a plugin/extension with a properties page and I can't get the FieldLayoutBuilder and JTextField's to behave.
I have set the FieldLayoutBuilder property StretchComponentsWithNoButton to false and yet when I run the extension and view my properties page (Tools->Preferences:PluginName) my JTextField is is fully expanded to the width of the panel.
        FieldLayoutBuilder b = new FieldLayoutBuilder(this);
        b.setStretchComponentsWithNoButton(false);My JTextField does not have a button and I would like it to be 45 pixels in width. Does setStretchComponentsWithNoButton doe anything? Am I using it correctly or should I do this another way?
pls help,
Brenden

Hi Shay,
thanks for helping with this.
I was thinking of using another layout control but wasn't sure if this would cause issues with the sizing of the JDev preferences panel or if the FieldLayoutBuilder is the preferred layout for the preferences dialog. There is only one example in the extension sdk (ConfigPanel extension) so I wasn't sure if FieldLayoutBuilder was used as the recommended approach or just for convenience of the example.
It's really the b.setStretchComponentsWithNoButton(false); that I am wondering what it is (not) doing.
    private void layoutControls() {
        FieldLayoutBuilder b = new FieldLayoutBuilder(this);
        b.setStretchComponentsWithNoButton(false);
        servers.setHorizontalAlignment(JTextField.RIGHT);
        servers.addKeyListener(new KeyAdapter() {
            public void keyTyped(KeyEvent e) {
            char c = e.getKeyChar();
            if (!((Character.isDigit(c) ||
                (c == KeyEvent.VK_BACK_SPACE) ||
                (c == KeyEvent.VK_DELETE)))) {
                getToolkit().beep();
                e.consume();
        browse.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    browse_actionPerformed(e);
        b.add(b.field().label().withText("&Command File:").component(cmdfile).button(browse).withText("..."));
        b.add(b.field().label().withText("&Start Servers:").component(servers));
        b.addVerticalSpring();
