12/*
13 All this is quite ugly but serves two purposes:
14 1. Be almost 100% compatible with old, untyped, wxList class
15 2. Ensure compile-time type checking for the linked lists
16
17 The idea is to have one base class (wxListBase) working with "void *" data,
18 but to hide these untyped functions - i.e. make them protected, so they
19 can only be used from derived classes which have inline member functions
20 working with right types. This achieves the 2nd goal. As for the first one,
21 we provide a special derivation of wxListBase called wxList which looks just
22 like the old class.

130 Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
131 for mingw 3.2.3 compiler bug that prevents a static function of liT class
132 from being exported into dll. A minimal code snippet reproducing the bug:
133
134 struct WXDLLEXPORT Foo
135 {
136 static void Bar();
137 struct SomeInnerClass
138 {
139 friend class Foo; // comment this out to make it link
140 };
141 ~Foo()
142 {
143 Bar();
144 }
145 };
146
147 The program does not link under mingw_gcc 3.2.3 producing undefined
148 reference to Foo::Bar() function
149
150
151 Note 2: the EmptyList is needed to allow having a NULL pointer-like
152 invalid iterator. We used to use just an uninitialized iterator object
153 instead but this fails with some debug/checked versions of STL, notably the
154 glibc version activated with _GLIBCXX_DEBUG, so we need to have a separate
155 invalid iterator.

653// -----------------------------------------------------------------------------
654// macros for definition of "template" list type
655// -----------------------------------------------------------------------------
656
657// and now some heavy magic...
658
659// declare a list type named 'name' and containing elements of type 'T *'
660// (as a by product of macro expansion you also get wx##name##Node
661// wxNode-derived type)
662//
663// implementation details:
664// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
665// for the list of given type - this allows us to pass only the list name
666// to WX_DEFINE_LIST() even if it needs both the name and the type
667//
668// 2. We redefine all non-type-safe wxList functions with type-safe versions
669// which don't take any space (everything is inline), but bring compile
670// time error checking.
671//
672// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
673// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
674// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
675// interesting capability to store polymorphic objects in the list and is
676// particularly useful with, for example, "wxWindow *" list where the
677// wxWindowBase pointers are put into the list, but wxWindow pointers are
678// retrieved from it.
679//
680// 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
681// WX_DECLARE_LIST_4 to allow defining classes without operator->() as
682// it results in compiler warnings when this operator doesn't make sense
683// (i.e. stored elements are not pointers)
