11 /*
12 All this is quite ugly but serves two purposes:
13 1. Be almost 100% compatible with old, untyped, wxList class
14 2. Ensure compile-time type checking for the linked lists
15
16 The idea is to have one base class (wxListBase) working with "void *" data,
17 but to hide these untyped functions - i.e. make them protected, so they
18 can only be used from derived classes which have inline member functions
19 working with right types. This achieves the 2nd goal. As for the first one,
20 we provide a special derivation of wxListBase called wxList which looks just
21 like the old class.

118 Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
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
122 struct WXDLLIMPEXP_CORE Foo
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
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.

646 // (as a by product of macro expansion you also get wx##name##Node
647 // wxNode-derived type)
648 //
649 // implementation details:
650 // 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
651 // for the list of given type - this allows us to pass only the list name
652 // to WX_DEFINE_LIST() even if it needs both the name and the type
653 //
654 // 2. We redefine all non-type-safe wxList functions with type-safe versions
655 // which don't take any space (everything is inline), but bring compile
656 // time error checking.
657 //
658 // 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
659 // a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
660 // generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
661 // interesting capability to store polymorphic objects in the list and is
662 // particularly useful with, for example, "wxWindow *" list where the
663 // wxWindowBase pointers are put into the list, but wxWindow pointers are
664 // retrieved from it.
665 //
666 // 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
667 // WX_DECLARE_LIST_4 to allow defining classes without operator->() as
668 // it results in compiler warnings when this operator doesn't make sense
669 // (i.e. stored elements are not pointers)
