JavaFX FadeTransition in after init is finished via controler - javafx

Question

I have this Application:
public class FOO extends Application {
private Scene scene;
#Override
public void start(Stage stage) throws Exception {
stage.initStyle(StageStyle.UNDECORATED);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
#Override
public void init() throws Exception {
URL resource = FXMLTabPaneController.class.getResource("FXMLTabPane.fxml");
System.out.println(resource);
Parent root = FXMLLoader.load(resource);
scene = new Scene(root);
}
}
And this as a controler:
public class FXMLTabPaneController implements Initializable {
#FXML
private TabPane tabPane;
#FXML
private AnchorPane anchorPane;
#Override
public void initialize(URL url, ResourceBundle rb) {
FadeTransition fadein = new FadeTransition(Duration.seconds(5), tabPane);
fadein.setFromValue(0);
fadein.setToValue(1);
fadein.play();
}
}
I wanted to show the Tabpane slowly after app start but it start with app Tabpane already seen.

Answer 1

Try this:
public class FXMLTabPaneController {
#FXML
private TabPane tabPane;
#FXML
private AnchorPane anchorPane;
#FXML
private void initialize() {
}
public void show(WindowEvent event) {
FadeTransition fadein = new FadeTransition(Duration.seconds(5), tabPane);
fadein.setFromValue(0);
fadein.setToValue(1);
fadein.play();
}
}
and FOO class
public class FOO extends Application {
private Scene scene;
private FXMLTabPaneController controller;
#Override
public void init() throws Exception {
super.init();
URL resource = FXMLTabPaneController.class.getResource("FXMLTabPane.fxml");
System.out.println(resource);
FXMLLoader loader = new FXMLLoader();
loader.setLocation(resource);
Parent root = loader.load();
controller = loader.getController();
scene = new Scene(root);
}
#Override
public void start(Stage stage) throws Exception {
stage.setOnShown(controller::show);
stage.initStyle(StageStyle.UNDECORATED);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}
