Clash Royale CLAN TAG #URR8PPP setOnAction restrictions and datepicker class I'm writing an application involved in time difference, there is something I don't get it, final DatePicker datePick=new DatePicker(); LocalDate time; Label label=new Label(); datePick.setOnAction(new EventHandler<ActionEvent>(){ public void handle(ActionEvent e){ time=datePick.getValue();//doesn't work, must 'LocalDate time=datePick.getValue(); label.setText(time);//doesn't work must label.setText("Time now:"+time) } }); It gives an error saying "Local variables referenced from an inner class must be final or effectively fine", anyway, all I did, declare 'time' variable inside setOnAction() and it worked, so what was wrong? and 'label.setText(time);' if I don't write some text inside, like 'label.setText("Time now: "+ time);' ,won't work too, that's weird, yet...

Clash Royale CLAN TAG #URR8PPP Scenebuilder throws nullpointer exception when using customcomponent I have a custom component like this: class SelectableVBox extends VBox { Node selectedNode private static PseudoClass selected = PseudoClass.getPseudoClass("selected") SelectableVBox() { super() addEventFilter(MouseEvent.MOUSE_CLICKED, { MouseEvent event -> if (event.button == MouseButton.PRIMARY) { def intersectedNode = NodeUtility.firstParentFullfilling(event.pickResult.intersectedNode, { node -> children.contains(node) }) if (intersectedNode == null) { return } if (selectedNode != null) { selectedNode.pseudoClassStateChanged(selected, false) } selectedNode = intersectedNode selectedNode.pseudoClassStateChanged(selected, true) } }) } } Basically it's a VBox which implements a very light selectionmodel that can then be used t...

Clash Royale CLAN TAG #URR8PPP Access a JavaFX TextArea within Tab returned from a TabPane I would like to access a text area placed within a Tab. All the Tabs in the TabPane will have a TextArea. Unfortunately Tab is not an interface and there does not seem a way to change the type held inside of the TabPane so I can not see a way to make code know that there is going to be a TextArea inside of the generic tab without keeping a separate list of them somewhere outside. TabPane can only return a Tab and tab does not distinguish that it holds a TextArea and even if I make an extension of Tab and give it to the TabPane it will still only return a Tab. Keeping an outside list seems really hacky and I dont think that would ever be the intended design. So what am I missing here. I am not using FXML. You can of course cast the content of a Tab . A more direct way than looking for it in this node is probably more hacky than storing the TextArea s in a proper data s...
