retrieve line drawn using drawpath

[shri_shri]

hi,


some lines of code i am attaching , here i face problem
is i can detect line with mouseevents using the drawpath ()
the problems is ,to detect no of line
whether i should declare no of path simultaneously

when i draw another line, starting position cordinates it get from previous linedrawn endposition cordinates

ie starting point of new line is the end point of the previous line

thanks
