JTextField suddenly too small

Question

Screenshot:

The textfield always worked fine, but suddenly was too small. You can still enter text, and when clicking the Print textJOptionPane.

I also tried both

JTextField tfld = new JTextField(10);

and

JTextField tfld = new JTextField("test adlfjsdlfjasdf");

but neither one helped.

Answer 1

try you use

         txtfield.setPreferredSize(new Dimension(int,int));

it will take parameters for Dimension you can read this for further assistance
