基本的javafx scenebuilder fxml文件导致错误

Question

我正在尝试创建一个基本的 window，中间有几个选项卡，第一个选项卡包含 table。

每次我运行主 java class 它都会给我错误，即使我摆脱了 table 和制表符。

这是我的主要文件：

package application;

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


public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            BorderPane root = (BorderPane)FXMLLoader.load(getClass().getResource("Sample.fxml"));
            Scene scene = new Scene(root,400,400);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

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

这是我的 fxml 文件：

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

         </children>
      </GridPane>
   </left>
</BorderPane>

任何帮助。我在这方面找不到任何东西，但这可能是我的 fxmlloader.load 文件源吗？我真的不知道。

这是我的错误代码：

Answer 1

你的 classpath 中有 NavigationDrawer.class 吗？

Caused by: java.lang.ClassNotFoundException: com.gluonhq.charm.glisten.control.NavigationDrawer

在您的 FXML 文件中：

<?import com.gluonhq.charm.glisten.control.NavigationDrawer?>

因此您的classpath 中需要NavigationDrawer.class 才能正确加载 FXML 文档。

如果没有，您需要从 gluonhq 下载它。

基本的javafx scenebuilder fxml文件导致错误
