VZ		 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 118 Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
30a29593
VZ		 119 for mingw 3.2.3 compiler bug that prevents a static function of liT class
120 from being exported into dll. A minimal code snippet reproducing the bug:
121
53a2db12 122 struct WXDLLIMPEXP_CORE Foo
30a29593
VZ		 123 {
124 static void Bar();
125 struct SomeInnerClass
126 {
127 friend class Foo; // comment this out to make it link
128 };
129 ~Foo()
130 {
131 Bar();
132 }
133 };
134
135 The program does not link under mingw_gcc 3.2.3 producing undefined
136 reference to Foo::Bar() function
7d13fbc6
VZ		 137
138
139 Note 2: the EmptyList is needed to allow having a NULL pointer-like
140 invalid iterator. We used to use just an uninitialized iterator object
141 instead but this fails with some debug/checked versions of STL, notably the
142 glibc version activated with _GLIBCXX_DEBUG, so we need to have a separate
143 invalid iterator.

ce3ed50d 648// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type

VZ		 649// for the list of given type - this allows us to pass only the list name
650// to WX_DEFINE_LIST() even if it needs both the name and the type
651//
ce3ed50d

653// which don't take any space (everything is inline), but bring compile
fd3f686c 654// time error checking.
f03fc89f
VZ		 655//
656// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
657// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
658// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
659// interesting capability to store polymorphic objects in the list and is
660// particularly useful with, for example, "wxWindow *" list where the
661// wxWindowBase pointers are put into the list, but wxWindow pointers are
662// retrieved from it.
6de44038
VZ		 663//
664// 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
665// WX_DECLARE_LIST_4 to allow defining classes without operator->() as
666// it results in compiler warnings when this operator doesn't make sense
