I appreciate your help, that worked ok. I was thinking maybe it would be
clear to have a delCurve() method, or something like this because for me
was not clear the SetPending and SetRelease methods. IMHO.
I have another questions:
1. I need to move the points for plot, viewing the curves sample I saw
there is a a2dStToolContr, the constructor for this object is
a2dStToolContr <cid:part1.03090705.04050208@gmail.com> (a2dCanvasView
<cid:part2.00090100.02010700@gmail.com> *view, wxFrame *where), my
problem is that the canvas is located in a wxDialog not a wxFrame, so
when I set this property I get a error. The other questions is that the
points are supossed to be move only in the x axis.
2. As I can move the points directly within the plot, I want to be move
from some spinCtrls, unfortunately I didn't find the way to do this neither.
Well, again thanks for any help you can give me. With this experience
I'm writing some how to with this control, to share it with everyone.

Ibraim
