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. | |

7d13fbc6 | 130 | Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround |
30a29593 VZ |
131 | for mingw 3.2.3 compiler bug that prevents a static function of liT class |
132 | from being exported into dll. A minimal code snippet reproducing the bug: | |
133 | ||
134 | struct WXDLLEXPORT Foo | |
135 | { | |
136 | static void Bar(); | |
137 | struct SomeInnerClass | |
138 | { | |
139 | friend class Foo; // comment this out to make it link | |
140 | }; | |
141 | ~Foo() | |
142 | { | |
143 | Bar(); | |
144 | } | |
145 | }; | |
146 | ||
147 | The program does not link under mingw_gcc 3.2.3 producing undefined | |
148 | reference to Foo::Bar() function | |
7d13fbc6 VZ |
149 | |
150 | ||
151 | Note 2: the EmptyList is needed to allow having a NULL pointer-like | |
152 | invalid iterator. We used to use just an uninitialized iterator object | |
153 | instead but this fails with some debug/checked versions of STL, notably the | |
154 | glibc version activated with _GLIBCXX_DEBUG, so we need to have a separate | |
155 | invalid iterator. | |

f03fc89f VZ |
671 | // |
672 | // 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of | |
673 | // a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most | |
674 | // generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes | |
675 | // interesting capability to store polymorphic objects in the list and is | |
676 | // particularly useful with, for example, "wxWindow *" list where the | |
677 | // wxWindowBase pointers are put into the list, but wxWindow pointers are | |
678 | // retrieved from it. | |
