Indeed. The reference would be:
But the wiki page seems more readable ad has screenshots:
It is quite old and you grasp the concept better with a Tutorial.
However keep it handy to read about concepts like "What is NSFirst" or
what a connection is.
I updated the classic tutorial a while a go:
You are not forced to use ProjectCenter, but for the beginning it is
convenient to have your make files created for you. You can edit source
files with the editor of your choice then.
I created an interface, then went to start creating messaging links
between objects (without really knowing where I was going, just trying
to get started somehow). I was wanting to tell the START button to
start a clock readout ticking in a text field.
Connections are done in the same way as in InterfaceBuilder: you select
the "source" then hit ctrl key and drag to the target. In the Inspector,
section "connections" you see the respective Outlets or Actions, select
the appropriate and then "connect'.
I believe the manual/guide said I would see an "S" and "T" on the
interface, I'm assuming Source and Target. I only saw a green circle
with "S" in it. And that stopped me dead in the water.
I'm very visual, and visuals can help me not get lost.
You visually link the objects (class instances essentially) and in the
inspector you choose the variable or method.
This is explained in the wiki page referenced above.
Back then, many years ago, I used several tutorials for OpenStep and for
the first MacOS X (10.0 aera) which were very similar in concept
(ProjectBuilder, InterfaceBuilder). However up to 10.4 IntrfaceBuilder
remained quite similar in concept.
Are there any commercial books, or websites with screenshots, etc,
that I can check out? Going from ground zero? I looked in the book
"Programming in Objective-C", and also "Objective-C Programming", and
saw no meaningful hits in the index for GNUStep or GORM. So, what
else is there?
I must admit however, that I learned more by trying myself and "opening"
examples and checking how they are done.
Most of our examples are code-based.
Most apps in GAP however are now gorm based.
I have some C++ and C# in my programming background, and have done
programming for a long time, but this whole scenario is a little new
It is. It was for me too. But it is just lovable and addicting.
You can definitely write commercial applications with GNUstep and
You won't be able to develop for your iPhone, but you can have code that
is easily ported to Mac.
The GNUstep Application Project is also a success story on how
applications can be maintained dual-platform.
Also, with the name GNUStep, does that mean this is open source, and
the open source rules of not being able to sell resulting apps would
apply? I got to GNUStep from thinking about doing some apps for my
iPhone. However, I don't have a Mac, just PC, so things pointed me
towards GNUStep. I would like to learn Objective-C in general, so not
all is lost.
