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

|
|
|
|
// declare a list type named 'name' and containing elements of type 'T *'
|
|
// (as a by product of macro expansion you also get wx##name##Node
|
|
// wxNode-derived type)
|
|
//
|
|
// implementation details:
|
|
// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
|
|
// for the list of given type - this allows us to pass only the list name
|
|
// to WX_DEFINE_LIST() even if it needs both the name and the type
|
|
//
|
|
// 2. We redefine all non-type-safe wxList functions with type-safe versions
|
|
// which don't take any space (everything is inline), but bring compile
|
|
// time error checking.
|
|
//
|
|
// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
|
|
// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
|
|
// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
|
|
// interesting capability to store polymorphic objects in the list and is
|
|
// particularly useful with, for example, "wxWindow *" list where the
|
|
// wxWindowBase pointers are put into the list, but wxWindow pointers are
|
|
// retrieved from it.
|
|
//
|
|
// 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
|
|
// WX_DECLARE_LIST_4 to allow defining classes without operator->() as
|
|
// it results in compiler warnings when this operator doesn't make sense
|
|
// (i.e. stored elements are not pointers)
|
|
|
|
// common part of WX_DECLARE_LIST_3 and WX_DECLARE_LIST_PTR_3
