java - JComponent not displaying on JPanel using GridBagLayout -

So after some research I am leaning towards specifying the size of my JComponent First hand, JComponent is not actually a preferred shape naturally.

Should I add a preferred size with my JComponent to my panel?

And if there is a way to fix this problem then what is the best way to do this? Ive read different people using setPreferedSize and others are saying that you should not use this method at all.
