Java'da tam ekran özel modunda klavyeden ve fareden gelen olayları nasıl ele alırsınız?

Question

Pasif oluşturma modunda, kullanıcıdan gelen olayları işlemek için KeyListener ve ActionListener arabirimlerini kullanabilirsiniz.

Tam ekran modunda olay işlemenin doğru yolu nedir?

Öyle görünüyor: fare tıklamasıyla ve anahtar basın olayları için uygulanmasını sağlayan bu iskelet uzatmak Lütfen, örnek (örnek penceresinde grafikleri güncellemek için bir Timer kullanarak, tam ekran münhasır modu başlar) kabartmak etmeyiniz How to Use Key Bindings ve How to Write a Mouse Listener'da gösterilen normal yaklaşımlar Full-Screen Exclusive Mode'da doğru şekilde çalışır.

olarak Mac OS X kullanıcıları tam ekran uygulamaları için farklı kullanıcı beklentileri olabilir, here önerdi. here'da gösterilen alternatif bir yaklaşım, "Mac OS X'te Java uygulamalarını ince ayarlamak için yerel özellikleri kullanmanın basit bir yolunu sağlayan" com.apple.eawt sınıflarına dayanır. FullScreenUtilities yöntemi setWindowCanFullScreen() yöntemi, özelliği etkinleştirir ve Application yöntemi requestToggleFullScreen(), ayarı dinamik olarak değiştirir. Genişlet simgesinin versions arasında nasıl değiştiğine dikkat edin.
