JTextField only shows as a slit Using GridBagLayout, need help

Question

Hi thank you in advance for any help, I'm trying to build a simple program to learn GUI's but when I run the code below my JTextFields all show as a slit thats not large enough for even one character.

cant post an image but it would look similar to: Label [|

where [| is what the text field actually looks like

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;


import javax.swing.*;

Adding those works for me:

    c.weightx=1.;
    c.fill=GridBagConstraints.HORIZONTAL;
