i have parent vbox holds menu button , draggable hbox. when drag hbox, menu button not responding (because hbox set on menu button). how set menu button on top of hbox if draggable?

you set draggablenode front in eventhandler onmousepressedproperty. puts draggablenode on top of sibling nodes , prevents menu button receiving mouse inputs.
to prevent this, see 2 options:
- don't set draggablenode front setting
movetofront = falseor, if isn't possible, set draggablenode again after dragging adding
onmousereleasedproperty().set(new eventhandler<mouseevent>() { @override public void handle(mouseevent event) { toback(); } });to init method of draggablenode.
for more general solution, add property draggablenode
private booleanproperty draginprocessproperty = new simplebooleanproperty(false); public booleanproperty draginprocessproperty() { return this.draginprocessproperty; } set property true while dragging in onmousedraggedproperty , false when mouse released
onmousereleasedproperty().set(new eventhandler<mouseevent>() { @override public void handle(mouseevent event) { draginprocessproperty.set(false); } }); and add changelistener draginprogressproperty in hboxandvboxexampleupdated
node.draginprocessproperty().addlistener(new changelistener<boolean>() { @override public void changed(observablevalue<? extends boolean> observable, boolean oldvalue, boolean newvalue) { if (!newvalue.booleanvalue()) { mainbox.tofront(); } } }); to set node front whenever dragging finished.
