I am using GtkDrawingArea for drawing images using cairo graphics. I
connected one call back function for draw event.
This call back will be executed multiple times. I am observing that, what
ever drawing happened in the previous call, is disappearing when the same
call back function is called next time.
I want to know how to retain the previously drawn image. If it is a sample
program, it will be more helpful to me.
Can some body please help me in this ?
Thanks & Regards
