Hi Antonio,
Thanks for your reply.
"
For instance, a IupCanvas, inside a IupVbox where you add another element.
Processing mouse callbacks on the IupCanvas is possible to move the box
around.
"
So this means I have a IupCanvas and then also have my iuptext overlapping
it? IupCanvas is used to get the mouse cursor position feedback to possibly
draw/erase a highlighting border around the iuptext box or to change the
position of the iuptextbox if there is a drag action on the mouse detected
by IupCanvas. Would that work?
Thanks,
Milind
