160 // Problem:
161 // The MSW version had problems with SetTextColour() et
162 // al as the wxListItemAttr's were stored keyed on the
163 // item index. If a item was inserted anywhere but the end
164 // of the list the the text attributes (colour etc) for
165 // the following items were out of sync.
166 //
167 // Solution:
168 // Under MSW the only way to associate data with a List
169 // item independant of its position in the list is to
170 // store a pointer to it in its lParam attribute. However
171 // user programs are already using this (via the
172 // SetItemData() GetItemData() calls).
173 //
174 // However what we can do is store a pointer to a
175 // structure which contains the attributes we want *and*
176 // a lParam for the users data, e.g.
177 //
178 // class wxListItemInternalData
179 // {
180 // public:
181 // wxListItemAttr *attr;
182 // long lParam; // user data
183 // };
