This section describes the so called @e "dynamic arrays". This is a C
array-like type safe data structure i.e. the member access time is constant
functions are inline, so they do not take @e any space at all.
wxWidgets has three different kinds of array. All of them derive from
- wxBaseArray class which works with untyped data and can not be used
+ wxBaseArray class which works with untyped data and cannot be used
directly. The standard macros WX_DEFINE_ARRAY(), WX_DEFINE_SORTED_ARRAY()
and WX_DEFINE_OBJARRAY() are used to define a new class deriving from it.
The classes declared will be called in this documentation wxArray,
however dumb, C++ compiler in the world.
Remember to include @<wx/arrimpl.cpp@> just before each

+ wxWidgets defines the following dynamic array types:
+ - ::wxArrayShort
+ - ::wxArrayInt
+ - ::wxArrayDouble
+ - ::wxArrayLong
+ - ::wxArrayPtrVoid
+
+ To use them you don't need any macro; you just need to include @c dynarray.h.
