मैं MenuBar बना रहा हूं, और Menu दबाकर कार्यक्षमता नहीं है: "फ़ाइल" और फिर एक क्रिया निष्पादित करें। ऐसा कोई अन्य fxml खोलना, या एक उदाहरण जहां कुछ आउटपुट लिखा गया है।जावाएफएक्स 2.0 मेनू मेनू जैसे मेनू को सक्रिय करना
मुझे MenuItem ("लगभग" झूठ बोलना) की कार्यक्षमता Menu में "फ़ाइल" जैसी कार्यक्षमता चाहिए।
