我目前正在编写一个名为Farkle的游戏。我想为代表骰子的每个矩形添加一个OnMouseClick事件。
我的问题是矩形无法识别MouseEvent。我使用Scene Builder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" />
矩形在网格窗格中，网格窗格在边框窗格的左侧排序。
这是我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;
就像我在开始时所说的，矩形无法识别鼠标事件。我用按钮尝试了同样的方法，它工作得很好。
这里有一些你可以分析的东西。
主要：
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

{
@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);
}
}
