I want to make a program with a full screen image with a text box ON TOP OF the image. I know how to do the full screen, and i know how to insert the image, but is there a way to add a JTextBox on top of the image, at a fixed position (where I specify the coordinates)???
Don't add a JLabel with an ImageIcon, but instead use something like Rob Camick's background panel. This allows you to add the JTextBox (you probably mean JTextArea) to that panel the usual way.
