I have a Graphic object that I am plotting data on. While the cursor is on
this object I have a cross-hairs cursor. What I would like to do is extend
lines from the cursor position to the edges of the graph (the perimeter)
but not have them overwrite what is plotted there and as I move the cursor
around the lines move accordingly.
It would be the same effect as using a selection tool in any common paint
program.
I know how to track the current mouse position and i know the values for
the boundaries of the graph; I just don't know how to produce the effect I
am wanting.
Has anyone ever accomplished this? Does anyone know HOW to do it? Any
help would be greatly appreciated.
