/**
+ The wxList<T> class provides linked list functionality.
- The wxList<T> class provides linked list functionality. It has been rewritten
- to be type safe and to provide the full API of the STL std::list container and
- should be used like it. The exception is that wxList<T> actually stores
- pointers and therefore its iterators return pointers and not references
- to the actual objets in the list (see example below) and @e value_type
- is defined as @e T*. wxList<T> destroys an object after removing it only
- if wxList::DeleteContents has been called.

+ wxList<T> destroys an object after removing it only if wxList<T>::DeleteContents

wxList<T> is not a real template and it requires that you declare and define
- each wxListT class in your program. This is done with @e WX_DECLARE_LIST
- and @e WX_DEFINE_LIST macros (see example). We hope that we'll be able
- to provide a proper template class providing both the STL std::list
- and the old wxList API in the future.
-
- Please refer to the STL std::list documentation for further
- information on how to use the class. Below we documented both
- the supported STL and the legacy API that originated from the
- old wxList class and which can still be used alternatively for
- the the same class.
-
- Note that if you compile wxWidgets in STL mode (wxUSE_STL defined as 1)
- then wxList<T> will actually derive from std::list and just add a legacy

+ provide a proper template class providing both the STL @c std::list and the old
+ wxList API in the future.
