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. | |

f03fc89f VZ |

664 | // 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of | |
665 | // a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most | |
666 | // generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes | |
667 | // interesting capability to store polymorphic objects in the list and is | |
668 | // particularly useful with, for example, "wxWindow *" list where the | |
669 | // wxWindowBase pointers are put into the list, but wxWindow pointers are | |
670 | // retrieved from it. | |
