60 // STRUCT SMYRECORD
61 // Under OS/2 we have to use our own RECORDCORE based struct if we have
62 // user data to store in a PM Container Control (and wxListCtrl is a PM
63 // Container in ICON, NAME, TEXT or DETAIL view). m_ulUserData is a four
64 // byte value containing a pointer to our CListIntemInternalData class
65 // instance.
66 //
67 // And now for the big time OS/2 Kludge. In traditional OS/2 PM
68 // applications using containers, programmers determine BEFORE creation
69 // how many records the view will have, initially, and how many columns
70 // the detail view of the container will have, as the container represents
71 // a known data block. Thus the OS/2 PM CV_DETAIL view, i.e.
72 // the wxWindows wxLC_REPORT view, relies on STATIC structure for its
73 // columnar data. It gets the data to display by telling it the specific
74 // offset of the field in the struct containing the displayable data. That
75 // data has be of OS/2 Types, PSZ (char string), CDATE or CTIME format.
76 // wxWindows is dynamic in nature, however. We insert columns, one at a
77 // time and do not know how many until the app is done inserting them. So
78 // for OS/2 I have to set a max allowable since they are fixed. We return
79 // an error to the app if they include more than we can handle.
80 //
81 // For example to display the data "Col 4 of Item 6" in a report view, I'd
82 // have to do:
83 // pRecord->m_pzColumn4 = "Col 4 of Item 6";
84 // pField->offStruct = FIELDOFFSET(MYRECORD, m_pzColumn4);
85 // and then call the PM API to set it.
86 //
87 // This really stinks but I can't use a pointer to another struct as the
88 // FIELDOFFSET call could only tell OS/2 the four byte value offset of
89 // pointer field and it would display giberish in the column.

111 // Problem:
112 // The MSW version had problems with SetTextColour() et al as the
113 // CListItemAttr's were stored keyed on the item index. If a item was
114 // inserted anywhere but the end of the list the the text attributes
115 // (colour etc) for the following items were out of sync.
116 //
117 // Solution:
118 // Under MSW the only way to associate data with a
119 // List item independant of its position in the list is to store a pointer
120 // to it in its lParam attribute. However user programs are already using
121 // this (via the SetItemData() GetItemData() calls).
122 //
123 // However what we can do is store a pointer to a structure which contains
124 // the attributes we want *and* a lParam for the users data, e.g.
125 //
126 // class CListItemInternalData
127 // {
128 // public:
129 // GuiAdvCtrl_CListItemAttr* pAttr;
130 // long lParam; // user data
131 // };
132 //
133 // To conserve memory, a CListItemInternalData is only allocated for a
134 // LV_ITEM if text attributes or user data(lparam) are being set.
