java可以在JavaFX中创建控制器数组吗?
我已经进行了一次很好的搜索,要么我没有使用正确的术语,要么这个问题还没有出现。我用Java编写代码已经有几年了,在过去的几周里,我刚刚开始使用JavaFX
背景:
我正在尝试创建一个应用程序,它实际上是一个测验,但我不希望每个问题都有一个新的窗格/选项卡,而是希望它们并排出现
我已经为一个问题创建了一个questionController,但是我不确定创建多个questionController的最佳方法,这些questionController都是由fx:id唯一标识的
我希望我的GUI是可伸缩的,这样用户就可以选择每轮显示的问题数量。如果不手动设置使用不同数量的控制器创建视图,我似乎无法解决如何做到这一点
我尝试过的事情
- 添加控制器网格窗格
- 在FXML中导入控制器
但这是不可伸缩的,因为我的按钮只是变成了button0-buttonN
如果你需要更多的信息,请告诉我
问题控制员。java
public class QuestionController implements Initializable {
@FXML
private ComboBox<String> chordCombo;
@FXML
private Label questionField;
@FXML
private Button submitButton;
@FXML
private ToggleGroup answerGroup;
@FXML
private RadioButton toggle0, toggle1, toggle2, toggle3, toggle4;
@Override
public void initialize(URL fxmlFileLocation, ResourceBundle resources) {
submitButton.setOnAction((event) -> {
System.out.println("Submit Logic");
});
answerGroup.selectedToggleProperty().addListener(new ChangeListener<Toggle>() {
public void changed(ObservableValue<? extends Toggle> ov, Toggle old_toggle, Toggle new_toggle) {
if (answerGroup.getSelectedToggle() != null) {
System.out.println(answerGroup.getSelectedToggle().toString());
}
}
});
}

我想你正在寻找这样的东西:
显然,如果在另一个FXML文件中定义了
TilePane
(或其他任何内容),并将其注入到另一个控制器中,则可以根据需要将相同的代码放入该控制器中的事件处理程序或初始化方法中
