ComboBox Items via Scene Builder?

Question

 <ComboBox fx:id="schaltung" layoutX="347.0" layoutY="50.0" prefHeight="63.0" prefWidth="213.0">
          <items>
                <FXCollections fx:factory="observableArrayList">
                    <String fx:id="reihe" fx:value="Reihenschaltung" />
                    <String fx:id="parallel" fx:value="Parallelschaltung" />
                </FXCollections>
            </items>
 </ComboBox>

I added this to my FXML file because I couldnt figure out where I could add Items to my ComboBox in the SceneBuilder. Is it possible to add items via the SceneBuilder, or do I have to do it manually?

Answer 1

You can't add items to combobox through SceneBuilder. Either you can add through FXML file as you did or through controller as given below.

@Override
public void initialize(URL location, ResourceBundle resources) {
    comboBox.getItems().removeAll(comboBox.getItems());
    comboBox.getItems().addAll("Option A", "Option B", "Option C");
    comboBox.getSelectionModel().select("Option B");
}

Answer 2

In response to saikosen comment: If Controller does not implement Initializable you can use :

@FXML
public void initialize() {
    comboBox.getItems().removeAll(comboBox.getItems());
    comboBox.getItems().addAll("Option A", "Option B", "Option C");
    comboBox.getSelectionModel().select("Option B");
}
