\section{\class{wxArray}}\label{wxarray}
This section describes the so called {\it dynamic arrays}. This is a C
you may find some useful hints about optimizing wxArray memory usage. As for executable size, all
wxArray functions are inline, so they do not take {\it any space at all}.
-wxWindows has three different kinds of array. All of them derive from
+wxWidgets has three different kinds of array. All of them derive from
wxBaseArray class which works with untyped data and can not 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
all of wxArray's functions are inline, so it costs strictly nothing to define as
many array types as you want (either in terms of the executable size or the
speed) as long as at least one of them is defined and this is always the case
-because wxArrays are used by wxWindows internally.
+because wxArrays are used by wxWidgets internally. This class has one serious
+limitation: it can only be used for storing integral types (bool, char, short,
+int, long and their unsigned variants) or pointers (of any kind). An attempt
+to use with objects of sizeof() greater than sizeof(long) will provoke a
+runtime assertion failure, however declaring a wxArray of floats will not (on
+the machines where sizeof(float) <= sizeof(long)), yet it will {\bf not} work,
+please use wxObjArray for storing floats and doubles (NB: a more efficient
+wxArrayDouble class is scheduled for the next release of wxWidgets).
wxSortedArray is a wxArray variant which should be used when searching in the
array is a frequently used operation. It requires you to define an additional
function for comparing two elements of the array element type and always stores
-its items in the sorted order (according to this function). Thus, it's
+its items in the sorted order (according to this function). Thus, it is
\helpref{Index()}{wxarrayindex} function execution time is $O(log(N))$ instead of
$O(N)$ for the usual arrays but the \helpref{Add()}{wxarrayadd} method is
slower: it is $O(log(N))$ instead of constant time (neglecting time spent in
memory allocation routine). However, in a usual situation elements are added to
an array much less often than searched inside it, so wxSortedArray may lead to
huge performance improvements compared to wxArray. Finally, it should be
-noticed that, as wxArray, wxSortedArray can not be used to store anything of
-sizeof() larger than max(sizeof(long), sizeof(void *)) - an assertion failure
-will be raised from the constructor otherwise.
+noticed that, as wxArray, wxSortedArray can be only used for storing integral
+types or pointers.
wxObjArray class treats its elements like "objects". It may delete them when
they are removed from the array (invoking the correct destructor) and copies
\begin{verbatim}
#include <wx/dynarray.h>
-// we must forward declare the array because it's used inside the class
+// we must forward declare the array because it is used inside the class
// declaration
class MyDirectory;
class MyFile;
...
// now that we have MyDirectory declaration in scope we may finish the
-// definition of ArrayOfDirectories
+// definition of ArrayOfDirectories -- note that this expands into some C++
+// code and so should only be compiled once (i.e., don't put this in the
+// header, but into a source file or you will get linking errors)
#include <wx/arrimpl.cpp> // this is a magic incantation which must be done!
WX_DEFINE_OBJARRAY(ArrayOfDirectories);
It is not as elegant as writing
-\begin{verbatim}
+\begin{verbatim}
typedef std::vector<MyDirectory> ArrayOfDirectories;
\end{verbatim}
Things are much simpler for wxArray and wxSortedArray however: it is enough
just to write
-\begin{verbatim}
-WX_DEFINE_ARRAY(MyDirectory *, ArrayOfDirectories);
-WX_DEFINE_SORTED_ARRAY(MyFile *, ArrayOfFiles);
+\begin{verbatim}
+WX_DEFINE_ARRAY_INT(int, ArrayOfInts);
+WX_DEFINE_SORTED_ARRAY_INT(int, ArrayOfSortedInts);
\end{verbatim}
+i.e. there is only one {\tt DEFINE} macro and no need for separate
+{\tt DECLARE} one.

+\membersection{Macros for template array definition}\label{arraymacros}
To use an array you must first define the array class. This is done with the
help of the macros in this section. The class of array elements must be (at
WX\_DEFINE\_OBJARRAY macro.

+\helpref{WX\_DEFINE\_USER\_EXPORTED\_OBJARRAY}{wxdefineobjarray}
+
+To slightly complicate the matters even further, the operator $->$ defined by
+default for the array iterators by these macros only makes sense if the array
+element type is not a pointer itself and, although it still works, this
+provokes warnings from some compilers and to avoid them you should use the
+{\tt \_PTR} versions of the macros above. For example, to define an array of
+pointers to {\tt double} you should use:
+
+\begin{verbatim}
+WX_DEFINE_ARRAY_PTR(double *, MyArrayOfDoublePointers);
+\end{verbatim}
+
+Note that the above macros are generally only useful for
+wxObject types. There are separate macros for declaring an array of a simple type,
+such as an int.
+
+The following simple types are supported:\\
+int\\
+long\\
+size\_t\\
+double
+
+To create an array of a simple type, simply append the type you want in CAPS to
+the array definition.
+
+For example, for an integer array, you'd use one of the following variants:

+\helpref{WX\_DEFINE\_EXPORTED\_ARRAY\_INT}{wxdefinearray}\\

Array classes are 100\% C++ objects and as such they have the appropriate copy
constructors and assignment operators. Copying wxArray just copies the elements
ARRAY\_MAXSIZE\_INCREMENT constant. Of course, this may lead to some memory
being wasted (ARRAY\_MAXSIZE\_INCREMENT in the worst case, i.e. 4Kb in the
current implementation), so the \helpref{Shrink()}{wxarrayshrink} function is
-provided to unallocate the extra memory. The \helpref{Alloc()}{wxarrayalloc}
