Hi all,

Any bode who know how to get the color information of a point
in the DrawingArea ?

In this area I have drawn several lines where the x/y point for
start en end location are in a array.
I need to find on a MouseDown event on a line the index in that array.

pts[0]=[1,2,3,4]
pts[1]=[5,6,7,8]

draw.begin(DrawingArea)
  for x = 0 to pts.count-1
    t=pts[x]
    draw.line(t[0],t[1],t[2],t[3])
  next
draw.end

sub DA_MouseDown()
  'find if point by mouse.x and .y is drawn in linecolor
  checkhit how?
end


TIA Ron.
