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