135// Problem:
73d8c5fd
RD
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
7cf46fdb 140// the following items were out of sync.
73d8c5fd 141//
7cf46fdb 142// Solution:
73d8c5fd
RD
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
7cf46fdb 147// SetItemData() GetItemData() calls).
73d8c5fd
RD
148//
149// However what we can do is store a pointer to a
150// structure which contains the attributes we want *and*
7cf46fdb 151// a lParam for the users data, e.g.
73d8c5fd 152//

7cf46fdb
VZ
157// long lParam; // user data
158// };
73d8c5fd
RD
159//
160// To conserve memory, a wxListItemInternalData is
