Question

嗨，我想添加1至24之间的“ Spinner”整数控件。我编写了函数，并添加到fxml文件中，但显示异常（JavaFX 11）。

通常，当我使用默认值“ 7”构建窗口显示微调器时，我也可以将int从1更改为24，但是每次单击都会显示此异常。总结

addChangeController

import java.net.URL;
import java.util.ResourceBundle;

public class addChangeController implements Initializable {


    @FXML
    private Spinner<Integer> fromHourSpinner;

    @FXML
    private Spinner<Integer> toHourSpinner;


    SpinnerValueFactory<Integer> spinner = new SpinnerValueFactory.IntegerSpinnerValueFactory(1,24,7);

    @FXML
    public void spinnersAction(ActionEvent event){
        //fromHourSpinner.setValueFactory(spinner);

    }

    @Override
    public void initialize(URL url, ResourceBundle resourceBundle) {
        fromHourSpinner.setValueFactory(spinner);

由于我有同样的问题，所以这是我找到的解决方法

只需要像这样重新排列一下代码即可。

 @Override
    public void initialize(URL url, ResourceBundle resourceBundle) {
SpinnerValueFactory<Integer> spinner =new SpinnerValueFactory.IntegerSpinnerValueFactory(1,24,7);
        fromHourSpinner.setValueFactory(spinner);
        toHourSpinner.setValueFactory(spinner);
    }

JavaFX控件微调器不起作用
