It used to return a pointer in wxUSE_STL==0 build and an object in wxUSE_STL==1 one making checking its return value difficult without provoking warnings from either MSVC or g++ (see #11038). Also, all the other occurrences of Member() already returned bool, including the one in wxStringList so changing it to return bool in wxList itself is more consistent. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@61966 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

/*
 | 
						|
  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.

    Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
 | 
						|
    for mingw 3.2.3 compiler bug that prevents a static function of liT class
 | 
						|
    from being exported into dll. A minimal code snippet reproducing the bug:
 | 
						|
 | 
						|
         struct WXDLLIMPEXP_CORE Foo
 | 
						|
         {
 | 
						|
            static void Bar();
 | 
						|
            struct SomeInnerClass
 | 
						|
            {
 | 
						|
              friend class Foo; // comment this out to make it link
 | 
						|
            };
 | 
						|
            ~Foo()
 | 
						|
            {
 | 
						|
                Bar();
 | 
						|
            }
 | 
						|
         };
 | 
						|
 | 
						|
    The program does not link under mingw_gcc 3.2.3 producing undefined
 | 
						|
    reference to Foo::Bar() function
 | 
						|
 | 
						|
 | 
						|
    Note 2: the EmptyList is needed to allow having a NULL pointer-like
 | 
						|
    invalid iterator. We used to use just an uninitialized iterator object
 | 
						|
    instead but this fails with some debug/checked versions of STL, notably the
 | 
						|
    glibc version activated with _GLIBCXX_DEBUG, so we need to have a separate
 | 
						|
    invalid iterator.

						|
//
 | 
						|
// 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
