63 // Container in ICON, NAME, TEXT or DETAILview). m_ulUserData is a four

75 // CLASS CListItemInternalData
76 //
77 // Problem:
78 // The MSW version had problems with SetTextColour() et al as the
79 // CListItemAttr's were stored keyed on the item index. If a item was
80 // inserted anywhere but the end of the list the the text attributes
81 // (colour etc) for the following items were out of sync.
82 //
83 // Solution:
84 // Under MSW the only way to associate data with a
85 // List item independant of its position in the list is to store a pointer
86 // to it in its lParam attribute. However user programs are already using
87 // this (via the SetItemData() GetItemData() calls).
88 //
89 // However what we can do is store a pointer to a structure which contains
90 // the attributes we want *and* a lParam for the users data, e.g.
91 //
92 // class CListItemInternalData
93 // {
94 // public:
95 // GuiAdvCtrl_CListItemAttr* pAttr;
96 // long lParam; // user data
97 // };
98 //
99 // To conserve memory, a CListItemInternalData is only allocated for a
100 // LV_ITEM if text attributes or user data(lparam) are being set.
101 //
102 // For OS/2, the lParam value points to whatever actual data we have
