Yessss. It does not work on the canvas pane, I suspect because of the 
pickOnBounds, but it does work on the stackpane. Plus, I can register to the 
stack pane without claiming the onMouseClick/Press hook.

Many thanks!

Hi Tom,
have you tried .addEventFilter() method? It receives the Event before the 
controls underneath the canvas, in the capturing phase. If you don't consume 
the Event, it should pass down to the controls.

Hi all,

Maybe someone has solved this already, so I thought I pop the question. 
Currently I'm working on CirclePopupMenu; a menu that is supposed to pop up on 
any place in a scene when a certain (usually the middle or right) mouse button 
is pressed.

Right now CirclePopupMenu requires a stackpane to which it binds itself. CirclePopupMenu 
initially places an empty "canvas" Pane on the stack pane, and will use that to 
render and position the menu when it needs to appear.

Also I need to monitor the mouse to detect if the menu should appear. In order 
to do that, I would like to use that canvas pane, but then any non relevant 
button clicks will not reach the underlying controls. In order to enable 
correct behavior I need to setPickOnBounds(false) on the pane, but then it does 
receive the mouse events anymore.

Is there any way to monitor mouse events but still pass them through to the 
underlying controls? In Swing I did something similar and used a system level 
mouse event hook.


PS: I'm not certain if the stackpane approach I've used is the best way to do 
this. It does work expect the mouse button problem. But any suggestions are
