HOW TO include button below sudoku puzzle? please help

[rated]

I have my basic sudoku program here (it hasnt been able to solve yet). After the user presses level 1, they will be taken to the puzzle itself.

I want to include a button below the puzzle. But everytime I try doing so, it messes up the order of the rows and columns. Can someone please help me create a JButton below the puzzle?

thanks

Didn't read most of your code, but if you want a button at the bottom, try this:

Java:

public void init() {   p.setLayout(new BorderLayout());   p.add(num0, BorderLayout.SOUTH);   num0.addActionListener(this);              }

You didn't put p.add(num0); Try adding the button to the panel p, you just put add, but no p.add...

You could also try p = (JPanel) frame.getContentPane();

^ For your frame, whatever it may be.



You could also try setting the frame visible to true At the end of the constructor, if nothing else works.

I know a few people in my class who copied my code after I pasted it, so in case my teacher checks this website, R.W. (intiails) wrote this...
