I can understand your position, kind of. However,
the line drawing has to follow the dragging of
the mouse *immediately*: because, for the user,
it represents the movement of the pen.
How, for example, would I handle rubberbanding,
if I were to follow your precept ("don't ever
draw anything in an event handler")? As compared
to rubberbanding of a large rectangle, I have
to draw a really only very tiny line segment when
incrementally drawing the pen-path from within
an event handler...
Regards,
Christian
P.S: No amount of clever coding seems to help
compensate for the fact that mouse-coordinates
are coarser than pen-coordinates on a Tablet PC
(because they are screen coordinates rather
than pen-digitizer coordinates) .
