I think all they are saying is to create several regular method

Well, one of the other things that I am confused about is declaring
the method. Does the name of the method in C have to be the same
as the "description" written in the REALmethodDefinition? (all
examples I have seen have shown the same name). I tried naming my
C methods "Constructor" but I had some sort of compile error.
A REALmethodDefinition maps a C-function to a RB method declaration.
So if you define a method map like
{ (REALproc) MyCMethodConstructor, REALnoImplementation, "Constructor
(p As Picture)" },
Then the user can only instantiate your class with: myClass As
yourClass = new yourClass(p). By defining a single constructor in the
REALmethodDefinition you also automatically disable the default
ability to call "new yourClass()".
A constructor in RB is just a method anyways
I currently am trying to have three constructors (though I would
rather have two with a default value). The problem is that the
constructor that I really want to use takes a Picture as a
parameter and all attempts to use this constructor have crashed.
Then you do something wrong elsewhere.
It is all so confusing... like Christian said:
"Over time you will learn that the RB SDK is a lot of guessing
and trying."
Yeah. It is not like the rest of the REALbasic experience, that is
for sure. Does anyone have a list of open-source plugins that I
can take a look at the source code? Other than that, all I can do
is take a look through the archives and ask questions to this list.
It is like an RB experience... And just forget about the
"Initializer" and "Finalizer" declarations. Those are never exposed
to the user of your plugin. They are only meant if you need to do
things under the hood. For example you need to allocate memory,
respectively deallocate memory. If it is a simple struct you are
dealing with, then the initializer and/or finalizer can be nil.
