qt. how to get a graphics item by position (x & y value)
Question
I drew some rectangles on a graphics view in qt creator. Now I want to get a rectangle to change its color and something else by its known position. Is it possible? I don't want to use for loop to check every rectangle's position. Is there an easy way? Thank you in the advanced!
