Question

每次在javafx DatePicker中点击周数和/或工作日时，是否可以触发事件？

我的意思是，我可以将actionListener设置为datepicker，当用户点击一天时，它会被触发。但那不是我想要的。我需要知道用户何时点击工作日本身的名称，或者本周的数量。

甚至可能吗？提前谢谢！

这应该让你朝着正确的方向前进。这演示了如何将onMouseClicked事件处理程序添加到Day of the Week节点。它还显示了如何为其他节点找出CSS。

密钥号码：

for (Node node : popupContent.lookupAll(".day-name-cell")) {
    DateCell tempDateCell = (DateCell) node;
    tempDateCell.setOnMouseClicked((event) -> {
        System.out.println("You clicked: " + tempDateCell.getText());
    });
}

完整代码：

import com.sun.javafx.scene.control.skin.DatePickerSkin;
import java.time.LocalDate;
import javafx.application.Application;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.DatePicker;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**

public class JavaFXApplication147 extends Application
{

    @Override
    public void start(Stage primaryStage)
    {
        DatePicker datePicker = new DatePicker(LocalDate.now());
        DatePickerSkin datePickerSkin = new DatePickerSkin(datePicker);
        Node popupContent = datePickerSkin.getPopupContent();

        //To see day of the week nodes
        for (Node node : popupContent.lookupAll(".day-name-cell")) {
            node.setOnMouseClicked((event) -> {
                DateCell dateCell = (DateCell) node;
                System.out.println("You clicked: " + dateCell.getText());
            });
        }

        //To see all nodes. Used to find out how to look up certain nodes
        System.out.println("\nAll nodes:");
        for (Node node : popupContent.lookupAll("*")) {
            System.out.println("\t" + node);
        }

        StackPane root = new StackPane(popupContent);
        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        launch(args);
    }

}

输出：
