点击了JavaFX形状

Question

所以我目前正在创建这个API。这个登录类应该创建一个包含所有需要的框的场景来创建一个GUI。我遇到的问题是，我的形状点击时不会做任何事情。我有事件监听器，但它不起作用。

import java.awt.Container; 
    import javafx.application.*; 
    import javafx.event.EventHandler; 
    import javafx.stage.*; 
    import javafx.scene.*; 
    import javafx.scene.layout.*; 
    import javafx.scene.paint.Color; 
    import javafx.scene.shape.Rectangle; 
    import javafx.scene.text.Font; 
    import javafx.scene.text.Text; 
    import javafx.scene.text.TextAlignment; 
    import javafx.scene.control.*; 
    import javafx.scene.image.Image; 
    import javafx.scene.image.ImageView; 
    import javafx.scene.input.MouseEvent; 

public class Login extends MainWindow { 
private Stage primaryStage; 
public static boolean ifContractor=false; 
public static boolean ifClient=false; 
private static Group root; 
private static ImageView iv; 

Login(){ 

} 
public static Scene loginScreen(){ 
    root = new Group(); 
    fillBackround(); 
    createShapes(); 
    System.out.println("I AM ROOT 3 : "+root); 

    Scene loginScene = new Scene(root, 1000,750); 
    return loginScene; 
} 
public static void fillBackround() { 
    Image loginBackround = new Image("loginBackround.jpg",true); 
    iv = new ImageView(); 
    iv.setImage(loginBackround); 
    root.getChildren().add(iv); 

} 
public static void createShapes() { 
    Group shapes = new Group(); 
    Rectangle mainBox = mainBox(); 
    Pane cornerBox = cornerBox(); 
    Pane clientBox = clientBox(); 
    Pane contractorBox = contractorBox(); 

    shapes.getChildren().addAll(mainBox,cornerBox,clientBox,contractorBox); 
    root.getChildren().add(shapes); 
} 
public static Rectangle mainBox() { 
    Rectangle mainBox = new Rectangle(350,100,300,500); 
    mainBox.setStroke(Color.BLUE); 
    mainBox.setFill(Color.DODGERBLUE); 
    mainBox.setStrokeWidth(3); 
    mainBox.setArcWidth(25);

    cornerBox.setFill(Color.DODGERBLUE); 
    cornerBox.setStrokeWidth(3); 
    cornerBox.setArcWidth(25); 
    cornerBox.setArcHeight(25); 
    cornerBox.setOpacity(0.5); 
    Text cornerText = new Text(370,150, null); 
    cornerText.setFont(new Font(25)); 
    cornerText.setFill(Color.WHITESMOKE); 
    cornerText.setWrappingWidth(200); 
    cornerText.setTextAlignment(TextAlignment.JUSTIFY); 
    cornerText.setText("Login as: "); 
    Pane cornerStack = new Pane(); 
    cornerStack.getChildren().addAll(cornerBox,cornerText); 
    return cornerStack; 
} 
public static Pane clientBox() { 
    Rectangle clientBox = new Rectangle(400,300,200,75); 
    clientBox.setStroke(Color.BLUE); 
    clientBox.setFill(Color.DODGERBLUE); 
    clientBox.setStrokeWidth(3); 
    clientBox.setArcWidth(25); 
    clientBox.setArcHeight(25); 
    clientBox.setOnMousePressed(new EventHandler<MouseEvent>() 
    { 
     @Override 
     public void handle(MouseEvent t) { 
      ifClient = true; 
      System.out.println("Has been clicked"); 
     } 
    }); 
    Text clientText = new Text(450,350, null); 
    clientText.setFont(new Font(25)); 
    clientText.setFill(Color.WHITESMOKE); 
    clientText.setWrappingWidth(200); 
    clientText.setTextAlignment(TextAlignment.JUSTIFY); 
    clientText.setText("CLIENT"); 
    Pane clientStack = new Pane(); 
    clientStack.getChildren().addAll(clientBox,clientText); 
    return clientStack; 
} 
public static Pane contractorBox() { 
    Rectangle contractorBox = new Rectangle(400,400,200,75); 
    contractorBox.setStroke(Color.BLUE); 
    contractorBox.setFill(Color.DODGERBLUE); 
    contractorBox.setStrokeWidth(3); 
    contractorBox.setArcWidth(25); 
    contractorBox.setArcHeight(25); 
    Text contractorText = new Text(415,450, null); 
    contractorText.setFont(new Font(25)); 
    contractorText.setFill(Color.WHITESMOKE); 
    contractorText.setWrappingWidth(200); 
    contractorText.setTextAlignment(TextAlignment.JUSTIFY); 
    contractorText.setText("CONTRACTOR"); 
    Pane contractorStack = new Pane(); 
    contractorStack.getChildren().addAll(contractorBox,contractorText); 
    return contractorStack; 
} 

} 

Answer 1

问题是你的Panes是互相重叠。当调用此：

shapes.getChildren().addAll(mainBox,cornerBox,clientBox,contractorBox); 

contractorBox（这是一个窗格）将在顶部，消耗所有的点击事件。

您应该在所有方法中使用相同的窗格。对于您可以使用下面的成员：

private static Pane pane = new Pane(); 

然后例如在cornerBox：

pane.getChildren().addAll(cornerBox,cornerText); 

这是这种情况下的解决方案，但：

这全班看起来很奇怪。你为什么要扩展MainWindow？没有意义。另外为什么每个人都是静态的？

你需要什么，一个扩展任何Parent（例如Group）的类，它用你想要的每一个控件填充Parent，然后返回Parent。那么你可以在任何你想要的地方：

Scene scene = new Scene(new Login()); 

我也不明白你为什么画矩形和文本。你基本需要的是两个按钮。您可以使用CSS修改按钮的外观：Example1，Example2。
