با سلام خدمت دوستان
من یه برنامه دریافت کردم که با GTK نوشته شده و مثل تخته وایت بورد هست که میتونی روش چیزی بنویسی اما حالا من میخوام رو این صفحه به صورت اتوماتیک یه خطوطی چاپ شه مثل ضربان قلب.از دوستان کسی میتونه کمکم کنه.در ضمن تا حدودی موفق شدم ولی برای رسم باید مدام کلیک کنم تا اون چیزی که میخوام ترسیم شه.
اینم کد به صورت کامل:
