 128 // Problem:
 129 // The MSW version had problems with SetTextColour() et
 130 // al as the wxListItemAttr's were stored keyed on the
 131 // item index. If a item was inserted anywhere but the end
 132 // of the list the the text attributes (colour etc) for
 133 // the following items were out of sync.
 134 //
 135 // Solution:
 136 // Under MSW the only way to associate data with a List
 137 // item independant of its position in the list is to
 138 // store a pointer to it in its lParam attribute. However
 139 // user programs are already using this (via the
 140 // SetItemData() GetItemData() calls).
 141 //
 142 // However what we can do is store a pointer to a
 143 // structure which contains the attributes we want *and*
 144 // a lParam for the users data, e.g.
 145 //
 146 // class wxListItemInternalData
 147 // {
 148 // public:
 149 //   wxListItemAttr *attr;
 150 //   long lParam; // user data
 151 // };
 152 //
 153 // To conserve memory, a wxListItemInternalData is
 154 // only allocated for a LV_ITEM if text attributes or
 155 // user data(lparam) are being set.
