Whiteboard GUI

I need help to fix my current Whiteboard program. You can compile it and run it, but does not currently do everything I want it to. My whiteboard currently has 3 function, Circle, Rectangle, and Erase. When Circle, Rectangle, or Erase is click it will print the word "Circle", "Rectangle" or "Erase on a 'Text area'. This currently works. I also need to implement mouseListener, when it enter,exit, click, dragged and display the coordinates or it. This is the part I need help with. I already handed this assignment in but I need it to work 100% before moving on because my next assignment that is already given makes me to actually draw the Circle if circle is clicked on and so on.

Code:
