Has anyone ever had issues with setting the preferred size of a
JComboBox using GridBagLayout? It seems the box's height is larger

can change the height of the JTextFields by using setPreferredSize()
to match the JComboBox so everything is uniform but that's only
because I can't decrease the JComboBox's height because it seems to
ignore that call. Any ideas?

Set the fill element on the GridBagConstraints for the JTextField.
Won't that make the JTextField match the size of the JComboBox? I want
the JComboBox to match the size of the JTextField (JComboBox has the
larger height due to the button for the dropdown box) which doesn't
work at the moment because it ignores the setPreferredSize() call.
JComboBoxes have a preferred size that is larger than a JTextField.
GridBagLayout uses only preferred size, not minimum size. So if you
really want to make the JComboBox smaller then you will have to do some
tricks. Set the minimum size to 1,1 and reset the preferred size to
match the height of the JTextField. I think I would just let my
JTextField get bigger to match the JComboBox but it does appear to work.

setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.insets = new Insets(2,2,2,2);
JComboBox cb = new JComboBox(array);
JTextField tf = new JTextField("test");
System.out.println(cb.getMinimumSize());
System.out.println(cb.getPreferredSize());
System.out.println(tf.getPreferredSize());
cb.setMinimumSize(new Dimension(1,1));
cb.setPreferredSize(new Dimension(cb.getPreferredSize().width,
tf.getPreferredSize().height));
thanks. I got it to work by doing that. I had tried to set the size
before but couldn't get it to work. I'm not sure what the difference
between your code and my previous code. By the way, I was able to leave
