Hi
I am interesting on Design Patterns
Where can I find some samples for learning it?
Thank You.

Whenever I see/hear people asking for code for patterns it worries me
slightly that they are missing the point. The whole thing about patterns
is that they are abstract. They are a general description of the sort of
approach you might use in a given situation, along with some pros and
cons, and so on. Any code you write is **not** the pattern, it is an
**implementation** of the pattern (sort of like the difference between a
class and an object). A pattern is most definitely **not** a code
template, where you just fill in the gaps.

There are many ways to implement any given pattern. It might be a case
of using a different approach (eg I'll tend to use classes where Joanna
will use interfaces), or it might be a case of leaving bits out or
adding bits to adapt the pattern to your situation. Normally you do not
use them in isolation either.

So code is fine so far as it goes, but that actually is not that far.
The important things to understand about a pattern are the solution it
encapsulates, and when it is appropriate to use it.

Cheers,
Jim Cooper

I mostly agree with your statement.

What I want to add is, I find source code is the best explanation.
Sometimes no matter how detail is the concept, is is still too abstract.

I finally understood MVC after I dug some code in SmallTalk and Java.

For MSJ, go to google.com, find with keywords : design patterns delphi.
  You will find a lot of links there.

I'm too lazy to read reams of someone else's code :-)

It's supposed to be abstract :-)

Jim Cooper

Ugh....  your argument is too strong.  Nothing can be said against
laziness.  :)

As do I.

Erwien, it's not _abstract_; it's _ambiguous_  and worse. If English was
a programming language, _hello world_ would not work.

Same here. I probably dug up the same stuff as you. You are right. The
only way to interpret most articles is in conjunction with the source,
provided it is _live code_.

As I heard half-way through a seminar...

"You people can't even agree on the meaning of the word "sex", yet you
believe you really understand what someone else is saying?!"

Hi,

That's a good one <g>

Phil

I just downloaded the demo version of ModelMaker & have started working
through the tutorial.  I notice with interest that it has a Patterns tab
with subtabs of Behavioral, Structural, Wizards & Templates.  It looks like
MM might be a good tool to use to learn patterns.

I know the feeling. As an instructor, I soon learned it was a waste of

It seems it is more important to look _kewl_ then actually learn
something. After all, you only have to _talk the talk_ to be accepted.
