How to display a tooltip according to mouse position? - JavaFX

Question

I have a stackPane, filled with a Circle and a couple of lines.

I want to display a tooltip while hovering over the StackPane and the tooltip should contain the X/Y coords of the mouse.

I know how to get the Coords of the mouse, but I'm unable to find a way of showing the tool tip.

Can any of ou guys help me with that?..

Solution 1

try this...

Tooltip tp = new Tooltip("at stack tool");
stackpane.setOnMouseEntered(new EventHandler<MouseEvent>() {
     @Override
     public void handle(MouseEvent t) {
          Node  node =(Node)t.getSource();
          tp.show(node, FxApp.stage.getX()+t.getSceneX(), FxApp.stage.getY()+t.getSceneY());
        }
    });

Solution 2

Anshul Parashar's answer probably works, but ToolTip also has a 'installation' static helper method to handle display on hover.

Assuming n is a Node:

Tooltip tp = new Tooltip("at stack tool");
Tooltip.install(n, tp);

Solution 3

I solved it like this:

    Tooltip mousePositionToolTip = new Tooltip("");
    gridPane.setOnMouseMoved(new EventHandler<MouseEvent>() {

        @Override
        public void handle(MouseEvent event) {
            String msg = "(x: " + event.getX() + ", y: " + event.getY() + ")\n(sceneX: "
                    + event.getSceneX() + ", sceneY: " + event.getSceneY() + ")\n(screenX: "
                    + event.getScreenX() + ", screenY: " + event.getScreenY() + ")";
            mousePositionToolTip.setText(msg);

            Node node = (Node) event.getSource();
            mousePositionToolTip.show(node, event.getScreenX() + 50, event.getScreenY());
        }

    });

It will show a ToolTip in right of your mouse-pointer. You can replace your StackPane with gridPane in my code and it should work. But i didn't test it.

ToolTip.install(n, tp); should be Tooltip.install(n, tp);

mixing awt and javafx is not a good idea when you need positions in the javafx reference system
