title: mouse pressed->drag->released. in java
body: <p>Excuse me:</p>
  
  <p>I just can't know how to link these successive operation? </p>
  
  <p>Mouse pressed and then drag then release. If an user doesn't do this operation some action won't happen...</p>
  
  <p>Should I add code as the is already pressed to distinguish that?</p>
  
  <p>The constant MOUSE_MOVED doesn't work since Eclipse told me it doesn't know it although I find the parameter in <a href="http://download.oracle.com/javase/1.4.2/docs/api/java/awt/event/MouseEvent.html#MOUSE_MOVED" rel="nofollow">mouse event api</a></p>
  
  <p>I don't know what's going on... Please help!</p>
