 140 // Problem:
 141 // The MSW version had problems with SetTextColour() et
 142 // al as the wxListItemAttr's were stored keyed on the
 143 // item index. If a item was inserted anywhere but the end
 144 // of the list the the text attributes (colour etc) for
 145 // the following items were out of sync.
 146 //
 147 // Solution:
 148 // Under MSW the only way to associate data with a List
 149 // item independant of its position in the list is to
 150 // store a pointer to it in its lParam attribute. However
 151 // user programs are already using this (via the
 152 // SetItemData() GetItemData() calls).
 153 //
 154 // However what we can do is store a pointer to a
 155 // structure which contains the attributes we want *and*
 156 // a lParam for the users data, e.g.
 157 //
 158 // class wxListItemInternalData
 159 // {
 160 // public:
 161 //   wxListItemAttr *attr;
 162 //   long lParam; // user data
 163 // };

 166 // only allocated for a LV_ITEM if text attributes or
 167 // user data(lparam) are being set.
