Salut j'ai le problème de javafx tableview. J'ai essayé des solutions mais je n'ai pas pu résoudre le problème. Il y a des lignes et peut basculer entre les lignes mais les données ne sont pas montrées. Je ne comprends pas où est le problème. Pourriez-vous m'aider à ce sujet?javafx tableview ne montrant pas la table de données créée avec scenebuilder
Ceci est classe User:
public enum Task {
ADMINISTRATOR("Yetkili Dispeçer"),
DISPATCHER("Dispeçer"),
MAINTENANCE_PERSON("Bakim Sorumlusu"),
OBSERVER("Gözlemci");
private String taskEnumString;
Task(String aTaskEnumString){
this.taskEnumString = aTaskEnumString;
}
public String getTaskEnumString(){return taskEnumString;}
}
//Görev property tanimi
private SimpleStringProperty aTask;
public String getTask(){
return aTask.get();
}
public void setTask(String task){
aTask.set(task);
}
public StringProperty taskProperty(){
return aTask;
}
//Username property tanimi
private SimpleStringProperty aUsername;
public String getUsername(){
return aUsername.get();
}
public void setUsername(String username){
aUsername.set(username);
}
public StringProperty usernameProperty(){
return aUsername;
}
//Password property tanimi
private SimpleStringProperty aPassword;
public String getPassword(){
return aPassword.get();
}
public void setPassword(String password){
aPassword.set(password);
}
public StringProperty passwordProperty(){
return aPassword;
}
//Firstname property tanimi
private SimpleStringProperty aFirstname;
public String getFirstname(){
return aFirstname.get();
}
public void setFirstname(String firstname){
aFirstname.set(firstname);
}
public StringProperty firstnameProperty(){
return aFirstname;
}
//Lastname property tanimi
private SimpleStringProperty aLastname;
public String getLastname(){
return aLastname.get();
}
public void setLastname(String lastname){
aLastname.set(lastname);
}
public StringProperty lastnameProperty(){
return aLastname;
}
//Lastname property tanimi
private SimpleBooleanProperty anIsActive;
public boolean getIsActive(){
return anIsActive.get();
}
public void setIsActive(boolean isActive){
anIsActive.set(isActive);
}
public BooleanProperty isActiveProperty(){
return anIsActive;
}
public User(String taks, String username, String password, String firstName, String lastName, boolean isActive){
this.aTask = new SimpleStringProperty(taks);
this.aUsername = new SimpleStringProperty(username);
this.aPassword = new SimpleStringProperty(password);
this.aFirstname = new SimpleStringProperty(firstName);
this.aLastname = new SimpleStringProperty(lastName);
this.anIsActive = new SimpleBooleanProperty(isActive);
}
et c'est classe contrôleur:
@FXML private javafx.scene.control.TableView<User> userTableView;
public void initialize() throws SQLException {

} catch (SQLException e) {
e.printStackTrace();
}
}

Parent root = fxmlLoader.load();

stage.setScene(new Scene(root));
stage.show();
}
//tablewiev'e kullanici eklenmesi
public void addUsers() throws SQLException {
data = FXCollections.observableArrayList();
try {
List<User> userList = Main.dbManager.getUserList();
if(userList.size() != 0){
for (int i=0; i<userList.size(); i++){
User aUser = userList.get(i);
data.add(aUser);
}
}
if(userTableView != null)
userTableView.setItems(data);

J'ai changé le code comme ça, mais je le même problème. La liste des données n'est pas vide J'ai vérifié.

Vous devez définir les usines de valeur sur vos colonnes. Voir la documentation de ['TableColumn'] (https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TableColumn.html) – Itai
Je crée des colonnes dynamiques avec un générateur de scènes. Vais-je encore utiliser des usines à valeur ajoutée? –
@ user1020141 salut, pouvez-vous poster votre code fxml pour nous faciliter de vérifier ou de faire un exemple pour vous – yab
