Just looked at the code and it seems Canvas does pick on bounds
independently of the pickOnBounds value. There's currently no logic for
picking only when over an opaque pixel ( worth filing a JIRA issue
maybe?). This makes Canvas to consume everything as it's always picked
instead of some controls underneath.
Unfortunately, I can't think of any solution that would work right now.
If we'd support Node picking
(https://javafx-jira.kenai.com/browse/RT-20184), it would be possible to
"redirect" an unwanted event to a different event target on that mouse
position.

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 welcome.
