awt - Tracking mouse movement in java -

i've been working on basic tower defense game , looking track movements of mouse. don't need track mouse movement when dragging when hovering on screen user can see tower going placed. i've extended mouseadapter make controller , clicking place tower works can't figure how track mouse movement otherwise. should overriding mousemoved this? tried little success. after putting print statement see event not firing. have currently:

public class mousecontroller extends mouseadapter {      private final board my_board;      private final int square_size;      public mousecontroller(final board the_board, final int the_square_size) {         my_board = the_board;         square_size = square_size;     }      @override     public void mouseclicked(final mouseevent e) {         super.mouseclicked(e);         point p = e.getpoint();         my_board.placetower(p.x / square_size, p.y / square_size - 1);     }      @override     public void mousemoved(final mouseevent e) {         super.mousemoved(e);         point p = e.getpoint();         my_board.placecursor(p.x / square_size, p.y / square_size - 1);     } } 

any appreciated. thanks!

here's official tutorial you're trying do: http://docs.oracle.com/javase/tutorial/uiswing/events/mousemotionlistener.html

here's relevant snippet inlined:

public class mousemotioneventdemo extends jpanel                                    implements mousemotionlistener {     //...in initialization code:         //register mouse events on blankarea , panel.         blankarea.addmousemotionlistener(this);         addmousemotionlistener(this);         ...     }      public void mousemoved(mouseevent e) {        saysomething("mouse moved", e);     }      public void mousedragged(mouseevent e) {        saysomething("mouse dragged", e);     }      void saysomething(string eventdescription, mouseevent e) {         textarea.append(eventdescription                          + " (" + e.getx() + "," + e.gety() + ")"                         + " detected on "                         + e.getcomponent().getclass().getname()                         + newline);     } }
