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.

7d13fbc6 130 Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
30a29593
VZ
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
53a2db12 134 struct WXDLLIMPEXP_CORE Foo
30a29593
VZ
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
7d13fbc6
VZ
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.

ce3ed50d 660// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type

VZ
661// for the list of given type - this allows us to pass only the list name
662// to WX_DEFINE_LIST() even if it needs both the name and the type
663//
ce3ed50d
JS
664// 2. We redefine all non-type-safe wxList functions with type-safe versions
665// which don't take any space (everything is inline), but bring compile
fd3f686c 666// time error checking.
f03fc89f
VZ
667//
668// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
669// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
670// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
671// interesting capability to store polymorphic objects in the list and is
672// particularly useful with, for example, "wxWindow *" list where the
673// wxWindowBase pointers are put into the list, but wxWindow pointers are
674// retrieved from it.
6de44038
VZ
675//
676// 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
677// WX_DECLARE_LIST_4 to allow defining classes without operator->() as
678// it results in compiler warnings when this operator doesn't make sense
