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

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