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, Tomas On Tue, Jun 10, 2014 at 1:45 PM, Tomas Mikula <tomas.mik...@gmail.com> wrote: > What about using Popup, which is a subclass of PopupWindow?
