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.

630// implementation details:
ce3ed50d 631// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
fd3f686c
VZ
632// for the list of given type - this allows us to pass only the list name
633// to WX_DEFINE_LIST() even if it needs both the name and the type
634//
ce3ed50d
JS
635// 2. We redefine all non-type-safe wxList functions with type-safe versions
636// which don't take any space (everything is inline), but bring compile
fd3f686c 637// time error checking.
f03fc89f
VZ
638//
639// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
640// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
641// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
642// interesting capability to store polymorphic objects in the list and is
643// particularly useful with, for example, "wxWindow *" list where the
644// wxWindowBase pointers are put into the list, but wxWindow pointers are
645// retrieved from it.
6de44038
VZ
646//
647// 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
648// WX_DECLARE_LIST_4 to allow defining classes without operator->() as
649// it results in compiler warnings when this operator doesn't make sense
650// (i.e. stored elements are not pointers)
