I created a sample solution for using a Task (as suggested in Alexander Kirov’s comment) to access a database on a concurrently executing thread to the JavaFX application thread. The relevant parts of the sample solution are reproduced below: // fetches a collection of names from a database. class FetchNamesTask extends DBTask<ObservableList<String>> { @Override protected … Read more
Use XYChart.Data.setNode(hoverPane) to display a custom node for each data point. Make the hoverNode a container like a StackPane. Add mouse event listeners so that you know when the mouse enters and leaves the node. On enter, place a Label for the value inside the hoverPane. On exit, remove the label from the hoverPane.

Looks like you have a slight logic error in your checkBounds routine – you are correctly detecting collisions (based on bounds) but are overwriting the fill of your block when you perform subsequent collision checks in the same routine. Try something like this – it adds a flag so that the routine does not “forget” … Read more
You can get the controller from the FXMLLoader FXMLLoader fxmlLoader = new FXMLLoader(); Pane p = fxmlLoader.load(getClass().getResource(“foo.fxml”).openStream()); FooController fooController = (FooController) fxmlLoader.getController(); store it in your main stage and provide getFooController() getter method. From other classes or stages, every time when you need to refresh the loaded “foo.fxml” page, ask it from its controller: getFooController().updatePage(strData); … Read more
