javafx矩形onmouseclick事件(fxml)

Question

我现在正在编写一个叫做“法克尔”的游戏。我想为每个表示骰子的矩形添加一个OnMouseClick事件。

我的问题是矩形不识别MouseEvent。我用场景生成器构建了我的GUI。这是我的FXML代码的摘录：

<Rectangle fx:id="recDice1" arcHeight="5.0" arcWidth="5.0" fill="WHITE" 
height="40.0" onMouseClicked="#recDice1_OnMouseClicked" stroke="BLACK" 
strokeType="INSIDE" width="40.0" GridPane.halignment="CENTER" 
GridPane.valignment="CENTER" />

矩形位于GridPane中，GridPane位于BorderPane的左侧。

这是我的Java代码的摘录：

@FXML private Rectangle recDice1;
@FXML public void recDice1_OnMouseClicked(MouseEvent event){
    System.out.println("Funktioniert!");
}

@Override
public void start(Stage primaryStage) {
    this.primaryStage = primaryStage;
    this.primaryStage.setTitle("Farkle");

    initLayout();

}

    public void initLayout(){
    try {
        //Erstelle FXMLLoader
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(getClass().getResource("../gui/FarkleGUI.fxml"));
        loader.setController(new FarkleControl());
        rootLayout = (BorderPane) loader.load();



        //Lade Szene
        Scene scene = new Scene(rootLayout);
        primaryStage.setScene(scene);
        primaryStage.setResizable(false);

        //Setze Grösse der Stage (Somit entfallen Margins)
        primaryStage.sizeToScene();

        //Zeige Szene
        primaryStage.show();
    } catch (IOException e) {
        e.printStackTrace();
    }
}


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

进口：

package java2.farkle.mlz.control;

import java.io.IOException;

import javafx.application.Application;

import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;

import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;

正如我在开头所说的，矩形不识别MouseEvent。我试过同样的按钮，效果很好。

这是一些你可以分析的东西。

Main：

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

/**
 *
 * @author blj0011
 */
public class Farkle extends Application
{

    @Override
    public void start(Stage stage) throws Exception
    {
        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));

        Scene scene = new Scene(root);

        stage.setScene(scene);
        stage.show();
    }

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

}

FXML：

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.RowConstraints?>
<?import javafx.scene.shape.Rectangle?>

<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="farkle.FXMLDocumentController">
    <children>
        <Button fx:id="button" layoutX="128.0" layoutY="155.0" onAction="#handleOnButtonAction" text="Click Me!" />
      <GridPane layoutX="6.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
        <columnConstraints>
          <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
          <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
        </columnConstraints>
        <rowConstraints>
          <RowConstraints minHeight="100.0" prefHeight="30.0" vgrow="SOMETIMES" />
        </rowConstraints>
         <children>
            <Rectangle fx:id="recDice1" arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="100.0" onMouseClicked="#handleOnMouseClicked" stroke="BLACK" strokeType="INSIDE" width="160.0" />
            <Rectangle fx:id="recDice2" arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="100.0" onMouseClicked="#handleOnMouseClicked" stroke="BLACK" strokeType="INSIDE" width="160.0" GridPane.columnIndex="1" />
         </children>
      </GridPane>
    </children>
</AnchorPane>
