Eigenschaftsbindungen in JavaFX TableView funktionieren nicht
Ich bin vielen Links gefolgt und habe eine Lösung gefunden, um das Kontrollkästchen in der Tabellenansicht anzuzeigen. Ich kann den Wert des Kontrollkästchens in der Tabellenansicht jedoch nicht ändern.
Link Ich folgte:Wie man CheckBox's zu einer TableView in JavaFX hinzufügt
Model Klasse:
public class TUser {
private SimpleStringProperty name;
private SimpleStringProperty address;
private SimpleBooleanProperty active;
public TUser(String name, String address, boolean active) {
this.name = new SimpleStringProperty(name);
this.address = new SimpleStringProperty(address);
this.active = new SimpleBooleanProperty(active);
}
public String getName() {
return name.get();
}
public void setName(String name) {
this.name = new SimpleStringProperty(name);
}
public String getAddress() {
return address.get();
}
public void setAddress(String address) {
this.address = new SimpleStringProperty(address);
}
public boolean getActive() {
return active.get();
}
public void setActive(boolean active) {
this.active = new SimpleBooleanProperty(active);
}
}
FXML-Datei:

Controller Klasse:
public class UserManagement extends AnchorPane {
@FXML
private TableView<TUser> usertable;
@FXML
private TableColumn<TUser, String> address;
@FXML
private TableColumn<TUser, String> name;
@FXML
private TableColumn<TUser, Boolean> active;
public UserManagement() throws IOException {
initGraphics();
initTable();
}
private class CheckBoxCellFactory<S, T> implements Callback<TableColumn<S, T>, TableCell<S, T>> {
@Override public TableCell<S, T> call(TableColumn<S, T> p) {
return new CheckBoxTableCell<>();
}
}
private void initGraphics() throws IOException {
FXMLLoader content = new FXMLLoader(getClass().getResource("/mypack/fxmls/UserManagement.fxml"));
content.setController(this);
Node contentnode = (Node) content.load();
AnchorPane.setBottomAnchor(contentnode, 0.0);
AnchorPane.setLeftAnchor(contentnode, 0.0);
AnchorPane.setRightAnchor(contentnode, 0.0);
AnchorPane.setTopAnchor(contentnode, 0.0);
getChildren().add(contentnode);
active.setCellFactory(new CheckBoxCellFactory<TUser, Boolean>());
address.setCellValueFactory(new PropertyValueFactory<TUser, String>("address"));
name.setCellValueFactory(new PropertyValueFactory<TUser, String>("name"));
active.setCellValueFactory(new PropertyValueFactory<TUser, Boolean>("active"));
}
private void initTable(){
ObservableList<TUser> data = FXCollections.observableArrayList(new TUser("ABC", "ABC Road", true));
usertable.setItems(data);
}
}
