 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 // };
 193 //
 194 // To conserve memory, a wxListItemInternalData is
 195 // only allocated for a LV_ITEM if text attributes or
 196 // user data(lparam) are being set.
