Please explain and give examples where Observer will not be useful.
Also, I
do not know what "faddy" means.
Having used it a lot recently, I'd prefer MVC to be used with in a
class library.
A Subscription mechanism is more powerful. Look at the MUSCLE C++
framework.
Iterator I use every day!!
I'd rather see a mechanism for injecting first class extensions to
existing classes.
* Interfaces don't work because you need to subclass them to get the
extra functionality. This is totally useless for things like
TCombobox.Items or
TMemo.Lines (like Michael explained) because such components uses
TStrings directly.
As Marco said - the underlying framework is fundamentally flawed. You
want to patch it. You need to redesign it. You are incredibly short
sighted here. Think outside of the box.
* Class Helpers like in Delphi.
No. Delphi is not the model for all change. Blinkers off. Look at
Objective-C categories or the Mix-In concept.
Talk is cheap. I'm not using pascal enough to justify coding. But if I
was doing this, I'd start again, as Marco suggests.
