How do I keep JTextFields in a Java Swing BoxLayout from expanding?

Question

I have a JPanel that looks something like this:

JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));

...

panel.add(jTextField1);
panel.add(Box.createVerticalStrut(10));
panel.add(jButton1);

panel.add(Box.createVerticalStrut(30));

panel.add(jTextField2);
panel.add(Box.createVerticalStrut(10));
panel.add(jButton2);

... //etc.

My problem is that the JTextFields become huge vertically. I want them to only be high enough for a single line, since that is all that the user can type in them. The buttons are fine (they don't expand vertically).

Is there any way to keep the JTextFields from expanding? I'm pretty new to Swing, so let me know if I'm doing everything horribly wrong.

Answer 1

set the max height. or put them in a scroll region

Answer 2

textField = new JTextField( ... );
textField.setMaximumSize( textField.getPreferredSize() );
