 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.
