My internet provider has problems sending to GMail addresses.
For me it worked to register to scene.getRoot().
I like registering to a node, because it allows to install different menu's to
different nodes, but still do the most common approach of install a single menu
to the top level pane.
Your code already uses addEventHandler, I adopted that.

Somehow I didn't get your previous email that you are quoting now.
Listening to MOUSE_MOVED events on the Scene seemed to work for me.
Didn't it work for you? You may as well install the menu to a Scene
instead of a Node. That will also simplify listening to scene's
events, because you don't have to worry about the case when the node
is not yet attached to the scene (when node.getScene() returns null).
By the way, you should probably use addEventHandler instead of
addEventFilter, to allow child nodes to consume the event if they want
to override the right click.

Ah, attaching to Node is a good idea after all!

Thanks for all the help, you've given me a lot of helpful tips. I already
was working on a popup based version and I see you ran into the same
problems as I did (initial popup had no width for the circularPane, etc),
the difference is that I bind the menu to Stage, since I do not envision
CirclePopupMenu as a context menu to a specific node. It could of course...
Uncertain about that.
Anyhow, the only remaining problem is hiding when the mouse exits. Stage
does not send the mouse events to addEventFilter. The node.addEventFilter
does not solve that and on scene I'm not getting the events either. But I
like the way it is going.
Thanks!

Here it is, using a Popup:

The nice thing about popup window is that it can extend beyond the
bounds of the owner window.
Just let me know if transparency works for you as expected. Some time
ago transparency stopped working on my system and I didn't care to
find out why, so my Popup has white background instead of transparent,
but should be transparent on a healthy system.

Just because I wanted to make minimal changes to your code, which was
already using StackPane. Yes, Popup would remove the need for a

Since talk is cheap, I slightly reworked your code (not using
PopupWindow) and it seems to work.
CircularPopupMenu:
https://github.com/TomasMikula/jfxtras-labs/blob/8.0/src/main/java/jfxtras/labs/scene/menu/CirclePopupMenu1.java
Sample:
https://github.com/TomasMikula/jfxtras-labs/blob/8.0/src/main/java/jfxtras/labs/scene/menu/Sample1.java
Main points:
* No "canvas" pane used, CircularPane is added directly to the stack
pane.
* CircularPane is added as the last child to the stack pane in order
to be on top.
* CircularPane is an "unmanaged" child of the stack pane, in order to
allow custom positioning (at mouse pointer)
* Since setPickOnBounds(false) causes the mouse exit the circular pane
as soon as it opens, there's slightly more logic to hide the menu
instead of just listening to MOUSE_EXITED events:
stackPane.addEventHandler(MouseEvent.MOUSE_MOVED, e -> {
if(isShown()) {
Bounds localBounds = circularPane.getBoundsInLocal();
Bounds screenBounds =
circularPane.localToScreen(localBounds);
if(!screenBounds.contains(e.getScreenX(),
e.getScreenY())) {
hide();
}
}
});
Cheers,

What about using Popup, which is a subclass of PopupWindow? You just
need
to
populate its content
popup.getContent().addAll(Node...);
and then show it at the right position, relative to any node
popup.show(canvas, x, y);

Been looking at the ContextMenu source code (which is extending
PopupControl), but it is somewhat mysterious how those MenuItems get
rendered. I would expect maybe a skin, but I'm not finding it.

Hi Tom,
I am in favor of the menu being a PopupWindow, but alternatively,
could your "canvas" be a Group instead of a Pane?
The code would look like this:
StackPane stack = new StackPane();
Group canvas = new Group();
canvas.setManaged(false);
stack.setOnMousePressed(e -> {
// layout in the top left corner of the stack pane
canvas.setLayoutX(0);
canvas.setLayoutY(0);
stack.getChildren().add(canvas);
});

Your event filter does work though for what I need now.
Thanks!

Oh, I see. So it's not a PopupWindow at all.
Events can pass only though parent-child hierarchy, so you can't
catch
an
Event in your "circular menu" pane and then pass it to some other
children
of the parent StackPane. The menu pane would have to be parent of
the
controls in the StackPane.
So again, you'd need RT-20184 to determine the target again by
temporarily
making the menu pane mouse transparent, doing Scene.pick and then
redirecting the Event by Event.fireEvent().
But I think reworking you menu to be a PopupWindow should work.
The
transparent areas in the circular menu should pass mouse events
to
the
underlying window.

Since the Pane is only used to draw the menu on when it need

calling it the canvas pane, as in "what is painted on".

Just looked at the code and it seems Canvas does pick on

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

Yessss. It does not work on the canvas pane, I suspect

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.
For more on the topic, see

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.
Tom
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.
