我的应用程序有选项卡式窗格，因此为了保持fxml文件的可管理性，我有一个包含选项卡的主fxml文件，以及每个其他选项卡的单独fxml。这工作正常，但由于某种原因，应用程序已停止加载第二个选项卡。我尝试在主应用程序中单独加载它，工作正常。我尝试创建一个新的fxml文件作为测试，并加载它，这也有效。但是，它不会将其加载到第二个选项卡中。此外，控制台没有输出。
编辑：经过多次试用，我将其缩小到分割窗格。我尝试了一个带有按钮的非常简单的fxml，这很好，但是添加了一个分割窗格和两个按钮，并且视图没有呈现。
这是我的主要课程： public class Main扩展Application {
@Override
public void start(Stage primaryStage) {
Parent mainView;
try {
mainView = FXMLLoader.load(getClass().getResource("view/MainView.fxml"));
Scene scene = new Scene(mainView);
primaryStage.setTitle("Horse Show Manager");
primaryStage.setScene(scene);
primaryStage.show();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
这是我的mainview.fxml

我认为回答我自己的问题可能是错误的形式......但解决方案是使用fx：define和fx：include标签定义两个选项卡。然后可以加载fxml内容。示例如下。
<TabPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="800.0"
prefWidth="800.0" tabClosingPolicy="UNAVAILABLE" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">
<fx:define>
<fx:include fx:id="groupPaneContent" source="GroupPane.fxml" />
<fx:include fx:id="riderPaneContent" source="RiderPane.fxml" />
</fx:define>
<tabs>
<Tab closable="false" text="Classes" content="$groupPaneContent" />
<Tab closable="false" text="Riders" content="$riderPaneContent" />
</tabs>
</TabPane>
编辑：最初，FXML无法正确呈现。我必须手动调整应用程序的大小，以便显示出来。如果您知道如何解决此问题，请发表评论
