Question

我的代码存在问题。这是我的第一个UI应用程序。我声明了我的标签，试图绑定一个值并修改它，但没有任何反应。显然问题是我的标签位于另一个窗格内的窗格内。在这种情况下如何修改我的标签？

Main.java

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("fxml/gui.fxml"));
        primaryStage.setTitle("program name");
        primaryStage.setScene(new Scene(root, 1280, 720));
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

myClasses \ Controller.java

package myClasses;

import javafx.beans.property.SimpleIntegerProperty;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import java.net.URL;
import java.util.ResourceBundle;

public class Controller implements Initializable{

    public Button hourglass;
    public Label currentMonthLabel;
    public SimpleIntegerProperty pastMonths = new SimpleIntegerProperty(1);

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        currentMonthLabel.textProperty().bind(pastMonths.asString());
        hourglass.setOnAction(e-> {
            pastMonths.setValue(pastMonths.getValue() + 1);
            System.out.println(pastMonths.getValue());
        });
    }
}
