java - Add touch gestures to legacy swing application -

i have legacy swing application need add touch gestures to,specifically pinch zoom , touch , drag.

i tried swingnode of jdk 8 , can run swing application there, display performance cut more 50% won't work. swingtexturerenderer in mt4j has same issue , without trying redispatch touch events mouse events.

i thought glass pane approach using javafx layer on top , capturing touch events , attempting dispatch them mouse events swing app underneath.

does have alternative approach? target platform windows 8.

bounty coming stackoverflow opens up. need 1 pretty rapidly.

edit:

here tried swingnode (the mouse redispatch didn't work). swingnode stuff might distraction best solution ignore if have better idea getting touch swing:

@override public void start(stage stage) {     final swingnode swingnode = new swingnode();     createandsetswingcontent(swingnode);      stackpane pane = new stackpane();     pane.getchildren().add(swingnode);      stage.setscene(new scene(pane, 640, 480));     stage.show(); }  private void createandsetswingcontent(final swingnode swingnode) {     swingutilities.invokelater(new runnable() {         @override         public void run() {             uilib.setplatformlookandfeel();              // create graphviewtouch             string datafile = null;             string label = "label";              final jpanel frame = graphview.demoframeless(datafile, label);             swingnode.setcontent(frame);             swingnode.setonzoom(new eventhandler<zoomevent>() {                 @override public void handle(zoomevent event) {                     mousewheelevent me = new mousewheelevent(frame, 1, system.currenttimemillis(), 0, (int)math.round(event.getscenex()), (int)math.round(event.getsceney()), (int)math.round(event.getscreenx()), (int)math.round(event.getscreeny()), (int)math.round(event.getzoomfactor()), false, mousewheelevent.wheel_unit_scroll, (int)math.round(event.getzoomfactor()), (int)math.round(event.getzoomfactor()), event.getzoomfactor());                     frame.dispatchevent(me);                     system.out.println("graphview: zoom event" +                         ", inertia: " + event.isinertia() +                          ", direct: " + event.isdirect());                      event.consume();                 }             });         }     }); } 

hmm... tough one, there chance.

what make multiple mouselistener classes (relative number of mouse events want pick up), , create sort of system detect adjustments, eg. (zoom)

1st listener:

    public void mousepressed(mouseevent e){     //set click true     clk = true;     //set first mouse position     firstpos = window.getmouseposition();     }      public void mousereleased(mouseevent e){      //set second mouse position     secondpos = window.getmouseposition();     } 

second listener

    public void mousepressed(mouseevent e){     //set clicked true     clk = true;     //set first mouse position (listener 2)     firstpos = window.getmouseposition();     }      public void mousereleased(mouseevent e){      //set second mouse position     secondpos = window.getmouseposition();     } 

main handler

    if(listener1.get1stmousepos() < listener1.get2ndmousepos() &&    listener2.get1stmousepos() < listener2.get2ndmousepos() && listener1.clk && listener2.clk){     zoommethod((listener1.get1stmousepos - listener1.get2ndmousepos()) +           (listener1.get1stlistener2.get2ndmousepos());      } 

and add window:

    window.addmouselistener(listener1);     window.addmouselistener(listener2); 

hope find way.
