event handling - Why is a MenuItem not responding? -

there contextmenu has 2 options , when second option (item2 in code) pressed right mousebutton want print out text know did activate it. till nothing happens when click on second mousebutton.

i haven't had experience yet eventhandlers apologies if made noobish mistake.

private void maakcontextmenu() {     menu = new contextmenu();     menuitem item = new menuitem("kleur assen");     menuitem item2 = new menuitem("tweede optie");     final lissajouscanvas canvas = this;     item.setonaction(new eventhandler<actionevent>() {          @override         public void handle(actionevent event) {             new kieskleur(canvas).show();         }     });     item2.addeventhandler(mouseevent.mouse_clicked, new eventhandler<mouseevent>(){          @override         public void handle(mouseevent t) {             system.out.println("in loop");             if(t.getsource()==mousebutton.secondary){                 system.out.println("in deep");             }             new kieskleur(canvas).show();         }      });     menu.getitems().addall(item, item2); } 

a menuitem not node, it's not part of scene graph in way nodes are. i'm not sure if bug or not; think implements eventtarget can generate actionevents. you'll have noticed there no setonmouseclicked(...) method available.

here's workaround. i'm not sure why works mouse_pressed , not mouse_clicked, it's default mouse event handling generates action events:

private void maakcontextmenu() {     menu = new contextmenu();     menuitem item = new menuitem("", new label("kleur assen"));     label menuitem2label = new label("tweede optie");     menuitem item2 = new menuitem("", menuitem2label);     final lissajouscanvas canvas = this;     item.setonaction(new eventhandler<actionevent>() {          @override         public void handle(actionevent event) {             new kieskleur(canvas).show();         }     });     menuitem2label.addeventhandler(mouseevent.mouse_pressed, new eventhandler<mouseevent>(){          @override         public void handle(mouseevent t) {             system.out.println("in loop");             if(t.getbutton()==mousebutton.secondary){                 system.out.println("in deep");             }             new kieskleur(canvas).show();         }      });     menu.getitems().addall(item, item2); }
