    I have written a custom widget using paint event and QPainter inheriting from QWidget. I am drawing tiny random circles with different colors in that widget. I am getting X and Y position using mouse event. How do i get the color which is present at position X and Y . I do not want to use graphics framework to draw tiny circles.

      You can render your current widget to an image, then get the pixel information from the image.
