我试图在同一窗口中打开一个新场景，但是出现了新窗口。我尝试了一些解决方法，但是打开新场景的按钮不起作用（单击时什么也没有发生），或者单击它时控制台中出现很多错误。我有什么可以做的吗？
主要：
package application;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.fxml.FXMLLoader;
public class Main extends Application {
@Override
public void start(Stage stage) {
try {
AnchorPane root = (AnchorPane)FXMLLoader.load(getClass().getResource("Sample.fxml"));
Scene scene = new Scene(root,706,552);
stage.setResizable(false);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
stage.setScene(scene);
stage.show();
} catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
控制器：
package application;
import java.io.*;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.*;
import javafx.fxml.FXMLLoader;
import javafx.scene.*;
import javafx.scene.control.*;
import javafx.fxml.*;
import javafx.stage.*;
public class SampleController implements Initializable{
@FXML
private Button start;
public void startGame(ActionEvent e) throws IOException
{
FXMLLoader fxmlLoader = new
FXMLLoader(getClass().getResource("/application/BoardView.fxml"));
Parent root1 = (Parent) fxmlLoader.load();
Stage stage = new Stage();
//set what you want on your stage
stage.initModality(Modality.APPLICATION_MODAL);
stage.setTitle("BoardView");
stage.setScene(new Scene(root1));
stage.setResizable(false);
stage.show();
}
@Override
public void initialize(URL arg0, ResourceBundle arg1) {
// TODO Auto-generated method stub
}
}
