我一直在尝试将项目添加到ListView。这些项目是在弹出窗口中创建的，我想将它们添加到主窗口中的ListView。
我想从TextField获得一些文本，它应该将该文本添加到主窗口中的ListView。
我是JavaFX的新手，所以我一直只使用“Scene Builder”和FXMLDocumentController.java。在main.java中没有做过任何工作。
所以我需要帮助我如何在弹出窗口中将项目添加到主窗口中的ListView 在控制器文档中的方法。
（两个FXML都有相同的控制器）
public class FXMLDocumentController implements Initializable {
ObservableList<String> list = FXCollections.observableArrayList("mark", "tom");
@FXML
private ListView<String> itemList = new ListView<String>(list);
@FXML
private Button tilføjGin = new Button();
@FXML
private TextArea GinNoter = new TextArea();
@FXML
private TextField GinNavn = new TextField();
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
itemList.setItems(list);
}
public void gemGin(ActionEvent event) {
Gin g = new Gin(GinNavn.getText(), GinNoter.getText());
// list.add(g.getName()); <--
// itemList.setItems(list); <--
ginAdd(g); <--These dont work for me.
Stage stage2 = (Stage) tilføjGin.getScene().getWindow();
stage2.close();
}
public void ginAdd(Gin gin) {
list.add(gin.getName()); <--
itemList.setItems(list); <-- None of these seems to work.
// itemList.getItems().add(gin.getName()); <--
}
@FXML
public void createNewGin(ActionEvent event) throws IOException {
Stage stage = new Stage();
Parent root;
root = FXMLLoader.load(getClass().getResource("FXML-PopUp.fxml"));
<-- My pop-up window
//create a new scene with root and set the stage
stage.setScene(new Scene(root));
stage.setTitle("My modal window");
stage.initModality(Modality.APPLICATION_MODAL);
stage.showAndWait();
}
如果你想看我的FXML： 弹出窗口fxml：
