 152 // Problem:
 153 // The MSW version had problems with SetTextColour() et
 154 // al as the wxListItemAttr's were stored keyed on the
 155 // item index. If a item was inserted anywhere but the end
 156 // of the list the the text attributes (colour etc) for
 157 // the following items were out of sync.
 158 //
 159 // Solution:
 160 // Under MSW the only way to associate data with a List
 161 // item independant of its position in the list is to
 162 // store a pointer to it in its lParam attribute. However
 163 // user programs are already using this (via the
 164 // SetItemData() GetItemData() calls).
 165 //
 166 // However what we can do is store a pointer to a
 167 // structure which contains the attributes we want *and*
 168 // a lParam for the users data, e.g.
 169 //
 170 // class wxListItemInternalData
 171 // {
 172 // public:
 173 //   wxListItemAttr *attr;
 174 //   long lParam; // user data
 175 // };

 177 // To conserve memory, a wxListItemInternalData is
 178 // only allocated for a LV_ITEM if text attributes or
 179 // user data(lparam) are being set.
