[net.micro.mac] GrafPort Scrolling Problems

drummond@nbs-amrf.UUCP (Brian Drummond) (03/22/85)

As near as I understand it, your first proposed solution to the problem
is the way to go about scrolling stuff around in a GrafPort.  I'll admit
it does get messy, but since you're only drawing the controls in a few
places (in response to update events or mouse down events in the grow box,
for example), I do't believe it's an unmanageable problem.

The current software suppliment (2/85) contains a sample program called
SCROLL which has the source (in what they call a 'vanilla version of C')
demonstrating scrolling a TE field and some graphics.  It shows how to
scroll both/either in the horizontal/vertical directions, and as far as it
goes, it's an educational experience...
