使用现有的JFXDialog脚本创建fxml

import com.jfoenix.controls.JFXButton;
import com.jfoenix.controls.JFXDialog;
import com.jfoenix.controls.JFXDialogLayout;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class JFXDialogExample extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        // 加载FXML文件
        Parent root = FXMLLoader.load(getClass().getResource("dialog.fxml"));

        // 创建JFXDialogLayout
        JFXDialogLayout dialogLayout = new JFXDialogLayout();
        dialogLayout.setBody(root);

        // 创建JFXDialog
        JFXDialog dialog = new JFXDialog();
        dialog.setContent(dialogLayout);

        // 创建一个按钮，用于关闭对话框
        JFXButton closeButton = new JFXButton("关闭");
        closeButton.setOnAction(event -> dialog.close());
        dialogLayout.setActions(closeButton);

        // 创建一个栈面板，用于显示对话框
        StackPane stackPane = new StackPane();
        stackPane.getChildren().add(dialog);

        // 创建场景和舞台
        Scene scene = new Scene(stackPane, 400, 300);
        primaryStage.setScene(scene);
        primaryStage.show();

        // 显示对话框
        dialog.show();
    }

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