Thanks Milind,
Do you know any further example codes that I could use for inspiration?
I would be specially interested in cases with, display an image + draw
polylines on top of it + point-n-click selection and edition of those
polylines/polygones.

Antonio can correct me if I am wrong but from the documentation I gather
that IupPlot is based on iupCanvas. All the axis drawing and click
select >facilities are implemented using the iupCanvas callbacks and
coordinate processing. IupCanvas is good and iupglcanvasbox is even more
powerful >you can put in other iup controls in the iupglcanvasbox and so
use their features and the canvas features in a hybrid manner but as I
learnt from my >previous discussions is not to get carried away by that
and only use controls which are necessary.

OK, I ported the pplot.cpp to Julia but using IupPlot.
Some questions:
- Can I select a line with a double-click instead of a Shift+Draw
Rectangle? Note that the first case needs only one hand, while both of
them are needed for later.
- How do one do an edit of type click-n-drag to move a point? I added a
DRAWSAMPLE_CB callback that is executed when I simulate a click-n-drag
but
again I've do that while holding down the Control key and it still
draws a
rectangle. Not practical.
- What you mean that IupPlot is much less flexible than cdCanvas?
Ok, with cdCanvas I can't select elements with the mouse nor draw axes
(severe limitations) but what are the important facilities that it
provides with respect to IupPlot?
Thanks
Joaquim
