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
