[Qt-interest] Qt Containers (or: why I must use STL)

The STL libraries tend to run really well but I can't stand the API for 
them (especially std::map). So I much prefer the Qt containers.

Aside from personal preference, I would guess the two main reason Qt has 
its own data containers are (1) for implicit data sharing, which is very 
useful for a lot of GUI stuff, and (2) to create clean and simple 
functions which can easily be used with signals and slots.

Although it makes the Qt API larger, I don't think it's 'fat' so much as 
'muscle' because it takes away from rather subtle (and dangerous) 
responsibilities away from the user code in a safe way.


Cheers,
Ian.
