170 // Problem:
171 // The MSW version had problems with SetTextColour() et
172 // al as the wxListItemAttr's were stored keyed on the
173 // item index. If a item was inserted anywhere but the end
174 // of the list the the text attributes (colour etc) for
175 // the following items were out of sync.
176 //
177 // Solution:
178 // Under MSW the only way to associate data with a List
179 // item independent of its position in the list is to
180 // store a pointer to it in its lParam attribute. However
181 // user programs are already using this (via the
182 // SetItemData() GetItemData() calls).
183 //
184 // However what we can do is store a pointer to a
185 // structure which contains the attributes we want *and*
186 // a lParam for the users data, e.g.
187 //
188 // class wxListItemInternalData
189 // {
190 // public:
191 // wxListItemAttr *attr;
192 // long lParam; // user data
193 // };

196 // only allocated for a LV_ITEM if text attributes or
197 // user data(lparam) are being set.
