Je rencontre des problèmes pour afficher les options de zone de liste déroulante dans javafx et le générateur de scènes.JavaFX et Scene Builder n'affichent pas les options de zone de liste modifiable
D'abord, j'ai essayé d'utiliser un tableau, ce qui, je suppose, ne fonctionne pas. J'ai ensuite essayé d'utiliser un ObservableList<String> et créer une instance de la zone de liste déroulante comme
ComboBox combo = new ComboBox(list);
Ce ne serait toujours pas afficher les options de combobox. classe contrôleur:
package javafxapplication1;
import javafxapplication1.JavaFXApplication1;
import java.net.URL;
import static java.util.Collections.list;
import java.util.ResourceBundle;
import javafx.collections.FXCollections;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.ComboBox;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javax.lang.model.element.Element;
/**

public class FXMLDocumentController implements Initializable {
ObservableList<String> options =
FXCollections.observableArrayList(
"Option 1",
"Option 2",
"Option 3"
);
@FXML
private Label label;
@FXML
private TextField dateText;
@FXML
private TextField time;
@FXML
private ComboBox band;
public void setTimeDate(){
JavaFXApplication1 javaFXApp = new JavaFXApplication1();
dateText.setText(javaFXApp.getDate());
}
public void setTime(){
JavaFXApplication1 javaFXApp = new JavaFXApplication1();
time.setText(javaFXApp.getTime());
}
@Override
public void initialize(URL url, ResourceBundle rb) {
band = new ComboBox(options);
}
}
Classe principale java:
public class JavaFXApplication1 extends Application {
private FXMLDocumentController initScene;
private DateFormat dtf;
@Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
public String getDate(){
dtf = new SimpleDateFormat("dd/MM/yy");
Date dateobj = new Date();
return dtf.format(dateobj);
}
public String getTime(){
dtf = new SimpleDateFormat("HH:mm;ss");
Date dateobj = new Date();
return dtf.format(dateobj);

Toute aide serait appréciée! Je suis un peu nouveau à cette substance de constructeur de scène et en utilisant javafx. Je suis juste en train de le contourner. Merci pour l'aide!
