165// Problem:
166// The MSW version had problems with SetTextColour() et
167// al as the wxListItemAttr's were stored keyed on the
168// item index. If a item was inserted anywhere but the end
169// of the list the the text attributes (colour etc) for
170// the following items were out of sync.
171//
172// Solution:
173// Under MSW the only way to associate data with a List
174// item independent of its position in the list is to
175// store a pointer to it in its lParam attribute. However
176// user programs are already using this (via the
177// SetItemData() GetItemData() calls).
178//
179// However what we can do is store a pointer to a
180// structure which contains the attributes we want *and*
181// a lParam for the users data, e.g.
182//
183// class wxListItemInternalData
184// {
185// public:
186// wxListItemAttr *attr;
187// long lParam; // user data
188// };
189//
190// To conserve memory, a wxListItemInternalData is
191// only allocated for a LV_ITEM if text attributes or
192// user data(lparam) are being set.
