JavaFX에서 장면 사이에 문자열을 전달하려고하는데 이미 some answers을 따라 갔지만 문자열이 새 장면에서 null이기 때문에 작동하지 않는 것으로 보입니다.속성 사이에 속성을 전달할 수 없습니다. JAvaFX
public class FXMLDocumentController implements Initializable {
@FXML
private Button btn_signup;
@FXML
private TextField et_username;
@FXML
private PasswordField et_password;
@FXML
private Hyperlink link_login;
Stage prevStage;
public void setPrevStage(Stage stage){
this.prevStage = stage;
}
@FXML
private void handleButtonAction(ActionEvent event) throws IOException {
if(btn_signup == event.getSource()){
Conector conn = new Conector();
if (conn.checkUser(et_username.getText(), et_password.getText())) {
FXMLLoader myLoader = new FXMLLoader(getClass().getResource("FXMLTasker.fxml"));
Pane myPane = (Pane)myLoader.load();
Scene scene = new Scene(myPane);
Stage stage = new Stage();
stage.setResizable(false);
stage.setScene(scene);
FXMLTaskerController controler = new FXMLTaskerController();
controler.setUser(et_username.getText());
myLoader.setController(controler);
prevStage.close();
stage.show();
}else {
JOptionPane.showMessageDialog(null, "Usuario o Contraseña incorrecta");
}
}else if (link_login == event.getSource()){
System.out.println("Registrate!");
}
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
여기 다른 클래스 controler를이야, 난 내 문자열을 원하는 하나를
여기 내 MainControler입니다. 세트를 사용하여
<?xml version="1.0" encoding="UTF-8"?>

당신은 내가 controler를 사용하려고 볼 수 있듯이과 :
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Hyperlink?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.control.PasswordField?>

<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.text.Font?>

<children>
<Label layoutX="215.0" layoutY="34.0" text="Sign In" textFill="WHITE">

</Label>

</children>
</AnchorPane>
그리고 다른 하나
public class FXMLTaskerController implements Initializable {
@FXML private ListView list_todo;
@FXML private ListView list_done;
@FXML public String username;
private void handleButtonAction(ActionEvent event) {
}
@Override
public void initialize(URL url, ResourceBundle rb) {
System.out.println(username);
list_todo.setCellFactory(new TaskCellFactory());
list_done.setCellFactory(new TaskCellFactory());
try {
getTasks();
} catch (IOException ex) {
Logger.getLogger(FXMLTaskerController.class.getName()).log(Level.SEVERE, null, ex);
}
}
public void setUser(String username){
this.username = username;
}
public void getTasks() throws IOException{
Conector con = new Conector();
for(Task task: con.obtenerTareas("pepin")){
System.out.println(task);
if(task.isState()){
list_done.getItems().add(task);
}else{
list_todo.getItems().add(task);
}
}
}
}
그리고 여기에는 fxml 파일입니다 문자열을 pasing, 문제는 내가 새로운 장면을 열 때, 그의 컨트롤러가 재설정하고 문자열이 더 이상, 어떤 생각이 왜 또는 어떻게 해결할 수 없다는 것입니다?
만약 내가이 오류가 발생 : 원인 : javafx.fxml.LoadException : 컨트롤러 값이 이미 지정되었습니다. Pane의 라인에서 myPane = (Pane) myLoader.load(); –
그것은 그것을 고쳤다! 고맙습니다! –
나는 JavaFX가 아니라고 확신한다. JAvaFX – ice1000
