 195 // Problem:
 196 // The MSW version had problems with SetTextColour() et
 197 // al as the wxListItemAttr's were stored keyed on the
 198 // item index. If a item was inserted anywhere but the end
 199 // of the list the text attributes (colour etc) for
 200 // the following items were out of sync.
 201 //
 202 // Solution:
 203 // Under MSW the only way to associate data with a List
 204 // item independent of its position in the list is to
 205 // store a pointer to it in its lParam attribute. However
 206 // user programs are already using this (via the
 207 // SetItemData() GetItemData() calls).
 208 //
 209 // However what we can do is store a pointer to a
 210 // structure which contains the attributes we want *and*
 211 // a lParam -- and this is what wxMSWListItemData does.
 212 //
 213 // To conserve memory, a wxMSWListItemData is
 214 // only allocated for a LV_ITEM if text attributes or
 215 // user data(lparam) are being set.
