167// Problem:
73d8c5fd
RD
168// The MSW version had problems with SetTextColour() et
169// al as the wxListItemAttr's were stored keyed on the
170// item index. If a item was inserted anywhere but the end
171// of the list the the text attributes (colour etc) for
7cf46fdb 172// the following items were out of sync.
73d8c5fd 173//
7cf46fdb 174// Solution:
73d8c5fd 175// Under MSW the only way to associate data with a List
43e8916f 176// item independent of its position in the list is to
73d8c5fd
RD
177// store a pointer to it in its lParam attribute. However
178// user programs are already using this (via the
7cf46fdb 179// SetItemData() GetItemData() calls).
73d8c5fd
RD
180//
181// However what we can do is store a pointer to a
182// structure which contains the attributes we want *and*
7cf46fdb 183// a lParam for the users data, e.g.
73d8c5fd 184//
