I have my two JTextFields identified in a GridLayout, but when I try to reformat them the stay as large as their positioning allows. I have tried to specify the size of the field but it never changes on the final product. Could this be because the GridLayout or something else? I have attached a screen shot so you can see the final product of my program.
