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

195 // only allocated for a LV_ITEM if text attributes or
