To be honest this is rather a large and open-ended question, a bit
like "how do I program a computer?" ;-)
Depending on what you want to do you might find a framework such as my
own DrawKit useful, though I have to warn you it's probably not ideal
for complete beginners with Cocoa. It will however handle much of the
basic creation (interactively) of objects in a drawing which could
well be a large part of what a flowcharting program would need to do.
You would, of course, be left with the task of turning those basic
objects into specific types that knew about flowcharting and
implementing a suitable data model for that.

If you do decide to go this route, you'll get a lot of help from
myself and others with specific points on the DK mailing list, and
general cocoa-related questions on this list.
hth,

Hi guys!
I am very new to Cocoa, but not new to UNIX development. GUI
programming is
new to me, and I am tackling it heavily ;)
I have a little assignment at work to create a simple application
which
charts a bunch of processes, much like OmniGraffle (
http://www.omnigroup.com/applications/omnigraffle/). I was wondering
how
such graphing was implemented, and more importantly, where to read.
I went
through the 3rd edition of Cocoa Programming for Mac OS X, but I
still dont
have any ideas on how to start implementing such a beast.
Can you please point me to potential topics and aspects of Cocoa I
should
research? I have played a little bit with quartz, but it seems too
complicated (or is it?) of a solution for the simple thing I am
trying to
achieve.
Any input is much appreciated!
Matt
