header include structure

[marsboee]

This must have been the MFC (or basic C++) class I slept through:

I have a typedef in a header file (for a CView subclass). I want to
use this type in another .h file.

How do I make this type available to another header (as a member
variable, for instance)? It (obviously) works to just include the .h
file with the typedef in the desired header, but I know this is bad
style and might cause problems in the future.

Thanks,
marsboee

No, it's not bad style. It's what you do. Alternatively, you could
duplicate the typedef in the other header, but that /is/ bad style and
might cause problems in the future. :-}

It is perfectly fine to include the class header file even if
you are just interested in one of the structures.

Checkout the following article about header file inclusion:

Why is it "bad style"? Unless you are talking about namespaces keeping
things cleaner, but even so those have to go into header files too if you're
going to use them in multiple places.
