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
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

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:
122 struct WXDLLIMPEXP_CORE Foo
125 struct SomeInnerClass
127 friend class Foo; // comment this out to make it link
135 The program does not link under mingw_gcc 3.2.3 producing undefined
136 reference to Foo::Bar() function
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

654 // which don't take any space (everything is inline), but bring compile
655 // time error checking.
657 // 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
