Use the PICKDATA method on the IDLgrWINDOW (obtained from
your draw widget as its value) to get this value.

Thanks for your fast reply,
PICKDATA works :D
I've been searching this functionality and I was starting to consider
applying trigonometry to get the point.
I've never thought that it could be done with just a line.
If anyone is trying it out there is a clear example in (examples/doc/
objects) surf_track.pro .
