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

 161 // only allocated for a LV_ITEM if text attributes or
