II Modul topshiriqlari

Timer bilan ishlovchi sinf ilovada takrorlanuvchi hodisalarni shakllantiradi. Hodisa Interval xossasida millisekundlarda koʻrsatilgan ma’lum bir davrda takrorlanadi. Enabled xossasiga true qiymat berish orqali timer ishga tushiriladi. Timerning har bir intervalida hodisa qayta ishlovchida koʻrsatilgan amallar bajariladi va odatda ilovada aks etadi. Shuni unutmaslik kerakki, animatsiya yaratishda chizmalar chizish Paint hodisasida joylashadi.
