Re: Adding a mouse listener to my Draughts game
Please post the full text of the compiler's error messages.I get an error
On which component(s) do you want the mouse's movements detected? Add the listener to that/those component(s).
If you don't understand my answer, don't ignore it, ask a question.

Re: Adding a mouse listener to my Draughts game
After the call to setBackground you'll probably need to call repaint() to have the new color shown.

Re: Adding a mouse listener to my Draughts game
I've worked out I need the row and column of the square the mouse is on (using e.getX() and e.getY() somehow?) and then I can just call the enter() method.
ie. squares[1][2].enter() changes the dark square on row 1 and column 2 to yellow whenever the mouse enters any dark square..... I don't know how to change the specific dark square the mouse is on though as opposed to hard coding a square to change color... thank you
Re: Adding a mouse listener to my Draughts game
If the squares are components, the event object passed to the listener method could have a reference to it.
Look at the getSource() method.

Re: Adding a mouse listener to my Draughts game
Hmm, I'm not quite sure what you mean.
I need the mouse listener to call the enter() method for the specific Square object that has called it :/
Re: Adding a mouse listener to my Draughts game
Look at the API doc for the event object that is passed to the mouse listener methods. If you can get a reference to the component that created the mouse event, you could call its methods.
For a visual look, add a call to println in the mouse listener that prints out the event object that is passed to the listener method.

Re: Adding a mouse listener to my Draughts game
Why not cast the reference returned by getSource() to the component's class that created the event and call its method directly.

Re: Adding a mouse listener to my Draughts game
Oh yeah, that was substantially better:
public void mouseEntered(MouseEvent e) { ((Square)e.getSource()).enter(); }
Thank you again Norm!
