191 // Problem:
192 // The MSW version had problems with SetTextColour() et
193 // al as the wxListItemAttr's were stored keyed on the
194 // item index. If a item was inserted anywhere but the end
195 // of the list the the text attributes (colour etc) for
196 // the following items were out of sync.
197 //
198 // Solution:
199 // Under MSW the only way to associate data with a List
200 // item independent of its position in the list is to
201 // store a pointer to it in its lParam attribute. However
202 // user programs are already using this (via the
203 // SetItemData() GetItemData() calls).
204 //
205 // However what we can do is store a pointer to a
206 // structure which contains the attributes we want *and*
207 // a lParam for the users data, e.g.
208 //
209 // class wxListItemInternalData
210 // {
211 // public:
212 // wxListItemAttr *attr;
213 // long lParam; // user data
