194// Problem:
73d8c5fd
RD
195// The MSW version had problems with SetTextColour() et
196// al as the wxListItemAttr's were stored keyed on the
197// item index. If a item was inserted anywhere but the end
198// of the list the the text attributes (colour etc) for
7cf46fdb 199// the following items were out of sync.
73d8c5fd 200//
7cf46fdb 201// Solution:
73d8c5fd 202// Under MSW the only way to associate data with a List
43e8916f 203// item independent of its position in the list is to
73d8c5fd
RD
204// store a pointer to it in its lParam attribute. However
205// user programs are already using this (via the
7cf46fdb 206// SetItemData() GetItemData() calls).
73d8c5fd
RD
207//
208// However what we can do is store a pointer to a
209// structure which contains the attributes we want *and*
7cf46fdb 210// a lParam for the users data, e.g.
73d8c5fd 211//

217// };
73d8c5fd

218//
219// To conserve memory, a wxListItemInternalData is
