我是Java和JavaFX的新手。
我可以使用以下主fxml文件启动我的主文件：
主文件：
package packages.home;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("Login.fxml"));
primaryStage.setTitle("mySportApp - Melvin CARRERE");
primaryStage.initStyle(StageStyle.UNDECORATED);
primaryStage.setScene(new Scene(root, 700, 500));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
这是我的Login.fxml文件（我启动主程序时会打印此Fxml文件）：

每次我尝试在另一个fxml上重定向用户时，当我单击btnCreate或BtnConnect按钮时，它都应该重定向。
我的问题是，每当我单击两个按钮之一时，此消息错误就会在控制台中显示，并且我无法显示新场景：

这是CreateController，它将成为我的用户创建帐户的一部分：

如果您想了解更多信息，昨天晚上，当我单击btnConnect时，数据库的连接正在工作，并且我已在另一页上重定向。
btnCreate重定向从未起作用。
感谢您在此问题上的所有帮助和支持。
如果您需要有关此主题的任何信息，请告诉我。
祝你有美好的一天！

好吧，感谢@Slaw他发现了我的问题：
我在控制器的handlButtonAction函数中使用了事件类型MouseEvent。但是我的按钮正在使用onAction函数，该函数使用事件：ActionEvent。
public void handleButtonAction(ActionEvent event) throws IOException{
if (event.getSource() == btnClose) {
System.exit(0);
System.out.println("Fermeture de l'application.");
}
if (event.getSource() == btnConnect) {
//login here
if (logIn().equals("Success")) {
// On affiche une nouvelle scene
try {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("dashboard.fxml"));
Parent root1 = (Parent) fxmlLoader.load();
Stage stage = new Stage();
stage.initModality(Modality.APPLICATION_MODAL);
stage.initStyle(StageStyle.UNDECORATED);
stage.setTitle("MyFit - Mon Dashboard");
stage.setScene(new Scene(root1));
stage.show();
} catch (Exception e){
System.out.println(e);
}
//add you loading or delays - ;-)
Node node = (Node) event.getSource();
Stage stage = (Stage) node.getScene().getWindow();
//stage.setMaximized(true);
stage.close();
}
}
我还添加了很好的导入：
import javafx.event.ActionEvent;
感谢您的帮助
