为javafx方法实现全局按键

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class GlobalKeyListener extends Application {

    @Override
    public void start(Stage primaryStage) {
        StackPane root = new StackPane();
        Scene scene = new Scene(root, 300, 200);

        scene.addEventFilter(KeyEvent.KEY_PRESSED, event -> {
            if (event.getCode() == KeyCode.F1) {
                // 执行按下F1键时的操作
                System.out.println("F1键被按下");
            } else if (event.getCode() == KeyCode.ESCAPE) {
                // 执行按下ESC键时的操作
                System.out.println("ESC键被按下");
            }
        });

        primaryStage.setScene(scene);
        primaryStage.show();
    }

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