Layout manager problem (horizontal & vertical boxes)

[David Johnson]

The code below produces the following inside one horizontal (master)box: A horizontal box containing a JComboBox, a JFormattedTextField, a JLabel, and a vertical box containing 4 JCheckBoxes.

My problem: The four items contained in the horizontal box are stretched vertically no matter what I do. I'd like to be able to control the vertical size.

Additionally, if anyone can point out a better way of doing this, I'm all ears. I'm certain that there must be a better way of doing this.

Thank you very much.
