Stackoverflow’da ne yazık ki artık soru soramıyorum kodu paylaşmama hiçbir şekilde izin vermiyor aynı sorunu yaşayan kişiler olmuş çözülmüyor ne yazık ki. O yüzden oraya soramadım.
Kod çok uzun o yüzden sadece sorun olan yeri belirtmek için yeniden düzenledim yardımcı olabilirseniz çok sevinirim.
2 hata var:
1.si

Bu hata programı etkilemiyor gibi, resmi düzgün bir şekilde çiziyor
2.si
Play düğmesine tıkladığımda, menü2’ye düzgün bir şekilde gidiyor.
Menu2’de geri butonuna tıkladığımda menu1’e gidiyor ama menu1’in yanında menu2’de çizilmesi gerekenleri de çiziyor.
Kısaca, her paint metodunda * yeniden çizmek * yerine ekranda mevcut çizimlerin * üzerine * çiziyor.
