运行 javaFX 应用程序同时使用图形视图和场景生成器时出现空 window
Empty window showing up when running javaFX application, using both graphic view and scenebuilder
我目前正在编写一个扑克游戏作为期末考试的作业。我必须使用组合视图：带有实际代码和 Scenebuilder 的 class。我做了我学到的一切，模型工作得很好。我是新手，所以一定很容易解决！教授们希望我们熟悉 Scenebuilder，但他们没有给出太多解释。
如您所见，我使用了一个名为 pokerView 的 class，我在其中加载了纸牌的每张图像。一开始我用了一个奇怪的forloop来自动生成图片的名字，打印出来url就可以了！
我也用场景生成器。它有自己的 controller/view class 即 FXMLpokerController
为了将这两者结合起来，我使用了 "super" 视图。
有趣的是 java 没有给我任何错误！
我真的很需要一个答案。如果 window 显示为空，我无法显示该应用程序。
所以终端在使用 printstacktrace 时给了我以下几行
javafx.fxml.LoadException:

您的 AnchorPane 有 fx:id "deal":
<AnchorPane id="AnchorPane" fx:id="deal" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">
在您的控制器 class FXMLpokerController 中，您将 "deal" 定义为按钮：
@FXML
private Button deal;
FXML 注入无法将 Button 初始化为 AnchorPane。将 fx:id 移动到正确的按钮并给你的 AnchorPane 一个不同的 fx:id.
您已在 FXML 中将 AnchorPane 命名为 "deal"，在控制器中将按钮命名为 "deal"。在初始化期间，映射是按名称完成的。由于这些对象不是同一类型，您会收到 class 异常。
如果按钮真的很重要，将 id 从 AnchorPane 移动到 FXML 中的按钮。基于此：
deal.setOnAction(this::deal);
我认为该按钮应称为交易。
更改此行
<AnchorPane id="AnchorPane" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">
和这一行
<Button fx:id="deal" layoutX="249.0" layoutY="495.0" mnemonicParsing="false" text="deal" />

您的 AnchorPane 有 fx:id "deal":
<AnchorPane id="AnchorPane" fx:id="deal" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">
在您的控制器 class FXMLpokerController 中，您将 "deal" 定义为按钮：
@FXML
private Button deal;
FXML 注入无法将 Button 初始化为 AnchorPane。将 fx:id 移动到正确的按钮并给你的 AnchorPane 一个不同的 fx:id.
您已在 FXML 中将 AnchorPane 命名为 "deal"，在控制器中将按钮命名为 "deal"。在初始化期间，映射是按名称完成的。由于这些对象不是同一类型，您会收到 class 异常。
如果按钮真的很重要，将 id 从 AnchorPane 移动到 FXML 中的按钮。基于此：
deal.setOnAction(this::deal);
我认为该按钮应称为交易。
更改此行
<AnchorPane id="AnchorPane" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">
和这一行
<Button fx:id="deal" layoutX="249.0" layoutY="495.0" mnemonicParsing="false" text="deal" />
