问题 I got a class where I receive some collection structure: public class YIFY { private static List<Pelicula> resultados; public static void setResultados(List<Pelicula> resultados) { YIFY.resultados = resultados; } } Later, at another class I associate the contents of such List to a TableView . However I create an FXCollections.observableArrayList() which is set as the bind element to the table. This is how I do it: peliculas = FXCollections.observableArrayList(YIFY.getResultados());

问题 There is a JAVAFX Scrollpane which contains a treeview. Inside the treeview, i have a few vboxs. Their height can change.

问题 I am creating a game in which you use guns and play against the computer/someone else. You can orient that gun with a slider. But I don't manage to orient the muzzle of the gun. I tried in different ways, nothing worked as expected. I googled a bit but I found nothing that worked and nothing that seems to have a chance of working. So I ask you, what haven't I tried yet ?

问题 This question already has answers here : JavaFX FXML controller - constructor vs initialize method (3 answers) Closed 3 years ago . This is likely pilot error, but the FXML attribute is not binding to the controller class on fx:id. I've whittled it down to a trivial example, but still "no joy". What am I overlooking?

问题 I try to cancel user selection in a ListView according a condition. I tried to consume mouse clicked and mouse pressed event in ListView and ListCell but it didn't work.

问题 .slider .track { -fx-pref-width: 300px; } .slider .axis-tick-label { -fx-text-fill: white; } My feeble attempts of writing CSS styles for the slider both don't work. I'm 100% sure my syntax is off.
