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.

139 Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
140 for mingw 3.2.3 compiler bug that prevents a static function of liT class
141 from being exported into dll. A minimal code snippet reproducing the bug:
142
143 struct WXDLLEXPORT Foo
144 {
145 static void Bar();
146 struct SomeInnerClass
147 {
148 friend class Foo; // comment this out to make it link
149 };
150 ~Foo()
151 {
152 Bar();
153 }
154 };
155
156 The program does not link under mingw_gcc 3.2.3 producing undefined
157 reference to Foo::Bar() function
158
159
160 Note 2: the EmptyList is needed to allow having a NULL pointer-like
161 invalid iterator. We used to use just an uninitialized iterator object
162 instead but this fails with some debug/checked versions of STL, notably the
163 glibc version activated with _GLIBCXX_DEBUG, so we need to have a separate
164 invalid iterator.

672 // (as a by product of macro expansion you also get wx##name##Node
673 // wxNode-derived type)
674 //
675 // implementation details:
676 // 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
677 // for the list of given type - this allows us to pass only the list name
678 // to WX_DEFINE_LIST() even if it needs both the name and the type
679 //
680 // 2. We redefine all non-type-safe wxList functions with type-safe versions
681 // which don't take any space (everything is inline), but bring compile
682 // time error checking.
683 //
684 // 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
685 // a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
686 // generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
687 // interesting capability to store polymorphic objects in the list and is
688 // particularly useful with, for example, "wxWindow *" list where the
689 // wxWindowBase pointers are put into the list, but wxWindow pointers are
690 // retrieved from it.
691 //
692 // 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
693 // WX_DECLARE_LIST_4 to allow defining classes without operator->() as
694 // it results in compiler warnings when this operator doesn't make sense
695 // (i.e. stored elements are not pointers)
