javafx-取消按ESC退出全屏模式的提示

只需要弹出窗口，然后全屏显示，并不需要上面提示的按ESC退出全屏模式的提示，可以在下面代码中加上就可以了：primaryStage.setFullScreenExitHint(“”);

package sample.main.alertt;

import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.image.Image;
import javafx.stage.Modality;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
import javafx.stage.WindowEvent;

import java.io.IOException;
import java.lang.management.ManagementFactory;

public class alertt  extends Application {
    public static void main(String[] args) {
        launch(args);
    }
    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = null;
        FXMLLoader loader = new FXMLLoader();

        try {
            loader.setLocation(getClass().getResource("/dialog.fxml"));
            root = loader.load();
            Label cc= (Label) root.lookup("#mes");
            cc.setText("333");
            System.out.println(root.lookup("#mes"));
            Scene scene = null;
            scene = new Scene(root, 1818, 810);
            primaryStage.setScene(scene);
            primaryStage.setFullScreen(true);
            primaryStage.setFullScreenExitHint("");
            primaryStage.setAlwaysOnTop(true);
            primaryStage.initStyle(StageStyle.TRANSPARENT);
            primaryStage.setResizable(false);
            primaryStage.show();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}
