Question

我正在尝试创建一个基本窗口，中间有几个标签，第一个标签包含一个表格。

每次运行主java类时，即使我摆脱了表格和标签，也会给我带来错误。

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：

</BorderPane>

一切都有帮助。我无法在此找到任何内容，但可能是我的fxmlloader.load文件源？我真的不知道。

Answer 1

您的NavigationDrawer.class中有classpath吗？

引起：java.lang.ClassNotFoundException： com.gluonhq.charm.glisten.control.NavigationDrawer

在您的FXML文件中，您有：

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

因此，您需要在NavigationDrawer.class中classpath正确加载FXML文档。

如果您不需要，请从gluonhq下载。

基本的javafx scenebuilder fxml文件会导致错误
