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