multithreading - Java FX Path Transition Control Transition Speed -


i trying slow down transition on mouse click event. want 2 things on mouse click event: change color of node (which circle) slow down speed of transition.

below have done in mouse click event 

         //creating mouse event handler         eventhandler<mouseevent> eventhandler = new eventhandler<mouseevent>() {        @override           public void handle(mouseevent e) {             system.out.println("hello world");             circleone.setfill(color.darkslateblue);                 try {              thread.sleep(500);                     } catch (interruptedexception ex) {        logger.getlogger(sequentialtransitionexample.class.getname()).log(level.severe, null, ex);    }  }  };

my problem node ciricle 1 not slowing down, color changes without problem. how can achieve controlling of transition speed?

thanks ( quite new java fx)
