26 * This code was audited for completeness against the documented features
27 * of Comctl32.dll version 6.0 on May. 20, 2005, by James Hawkins.
29 * Unless otherwise noted, we believe this code to be complete, as per
30 * the specification mentioned above.
31 * If you discover missing features, or bugs, please note them below.
35 * Default Message Processing
36 * -- EN_KILLFOCUS should be handled in WM_COMMAND
37 * -- WM_CREATE: create the icon and small icon image lists at this point only if
38 * the LVS_SHAREIMAGELISTS style is not specified.
39 * -- WM_WINDOWPOSCHANGED: arrange the list items if the current view is icon
40 * or small icon and the LVS_AUTOARRANGE style is specified.
45 * -- Hot item handling, mouse hovering
46 * -- Workareas support
51 * -- Expand large item in ICON mode when the cursor is flying over the icon or text.
52 * -- Support CustomDraw options for _WIN32_IE >= 0x560 (see NMLVCUSTOMDRAW docs).
53 * -- LVA_SNAPTOGRID not implemented
54 * -- LISTVIEW_ApproximateViewRect partially implemented
55 * -- LISTVIEW_[GS]etColumnOrderArray stubs
56 * -- LISTVIEW_SetColumnWidth ignores header images & bitmap
57 * -- LISTVIEW_SetIconSpacing is incomplete
58 * -- LISTVIEW_StyleChanged doesn't handle some changes too well
61 * -- LISTVIEW_GetNextItem needs to be rewritten. It is currently
62 * linear in the number of items in the list, and this is
63 * unacceptable for large lists.
64 * -- if list is sorted by item text LISTVIEW_InsertItemT could use
65 * binary search to calculate item index (e.g. DPA_Search()).
66 * This requires sorted state to be reliably tracked in item modifiers.
67 * -- we should keep an ordered array of coordinates in iconic mode
68 * this would allow to frame items (iterator_frameditems),
69 * and find nearest item (LVFI_NEARESTXY) a lot more efficiently
76 * -- LVIS_ACTIVATING (not currently supported by comctl32.dll version 6.0)
83 * -- LVS_NOSCROLL (see Q137520)
84 * -- LVS_SORTASCENDING, LVS_SORTDESCENDING
86 * -- LVS_TYPESTYLEMASK
89 * -- LVS_EX_BORDERSELECT
91 * -- LVS_EX_HEADERDRAGDROP
94 * -- LVS_EX_MULTIWORKAREAS
96 * -- LVS_EX_SIMPLESELECT
97 * -- LVS_EX_TWOCLICKACTIVATE
98 * -- LVS_EX_UNDERLINECOLD
99 * -- LVS_EX_UNDERLINEHOT
102 * -- LVN_BEGINSCROLL, LVN_ENDSCROLL
105 * -- LVN_MARQUEEBEGIN
111 * -- LVM_CANCELEDITLABEL
112 * -- LVM_ENABLEGROUPVIEW
113 * -- LVM_GETBKIMAGE, LVM_SETBKIMAGE
114 * -- LVM_GETGROUPINFO, LVM_SETGROUPINFO
115 * -- LVM_GETGROUPMETRICS, LVM_SETGROUPMETRICS
116 * -- LVM_GETINSERTMARK, LVM_SETINSERTMARK
117 * -- LVM_GETINSERTMARKCOLOR, LVM_SETINSERTMARKCOLOR
118 * -- LVM_GETINSERTMARKRECT
119 * -- LVM_GETNUMBEROFWORKAREAS
120 * -- LVM_GETOUTLINECOLOR, LVM_SETOUTLINECOLOR
121 * -- LVM_GETSELECTEDCOLUMN, LVM_SETSELECTEDCOLUMN
122 * -- LVM_GETISEARCHSTRINGW, LVM_GETISEARCHSTRINGA
123 * -- LVM_GETTILEINFO, LVM_SETTILEINFO
124 * -- LVM_GETTILEVIEWINFO, LVM_SETTILEVIEWINFO
125 * -- LVM_GETUNICODEFORMAT, LVM_SETUNICODEFORMAT
126 * -- LVM_GETVIEW, LVM_SETVIEW
127 * -- LVM_GETWORKAREAS, LVM_SETWORKAREAS
128 * -- LVM_HASGROUP, LVM_INSERTGROUP, LVM_REMOVEGROUP, LVM_REMOVEALLGROUPS
129 * -- LVM_INSERTGROUPSORTED
130 * -- LVM_INSERTMARKHITTEST
131 * -- LVM_ISGROUPVIEWENABLED
132 * -- LVM_MAPIDTOINDEX, LVM_MAPINDEXTOID
134 * -- LVM_MOVEITEMTOGROUP
136 * -- LVM_SETTILEWIDTH

143 * -- ListView_GetNumberOfWorkAreas
144 * -- ListView_GetUnicodeFormat, ListView_SetUnicodeFormat
145 * -- ListView_GetWorkAreas, ListView_SetWorkAreas
150 * Known differences in message stream from native control (not known if
151 * these differences cause problems):
152 * LVM_INSERTITEM issues LVM_SETITEMSTATE and LVM_SETITEM in certain cases.
153 * LVM_SETITEM does not always issue LVN_ITEMCHANGING/LVN_ITEMCHANGED.
154 * WM_CREATE does not issue WM_QUERYUISTATE and associated registry
155 * processing for "USEDOUBLECLICKTIME".

997 * ITERATOR DOCUMENTATION
999 * The iterator functions allow for easy, and convenient iteration
1000 * over items of interest in the list. Typically, you create a
1001 * iterator, use it, and destroy it, as such:
1004 * iterator_xxxitems(&i, ...);
1005 * while (iterator_{prev,next}(&i)
1007 * //code which uses i.nItem
1009 * iterator_destroy(&i);
1011 * where xxx is either: framed, or visible.
1012 * Note that it is important that the code destroys the iterator
1013 * after it's done with it, as the creation of the iterator may
1014 * allocate memory, which thus needs to be freed.
1016 * You can iterate both forwards, and backwards through the list,
1017 * by using iterator_next or iterator_prev respectively.
1019 * Lower numbered items are draw on top of higher number items in
1020 * LVS_ICON, and LVS_SMALLICON (which are the only modes where
1021 * items may overlap). So, to test items, you should use
1023 * which lists the items top to bottom (in Z-order).
1024 * For drawing items, you should use
1026 * which lists the items bottom to top (in Z-order).
1027 * If you keep iterating over the items after the end-of-items
1028 * marker (-1) is returned, the iterator will start from the
1029 * beginning. Typically, you don't need to test for -1,
1030 * because iterator_{next,prev} will return TRUE if more items
1031 * are to be iterated over, or FALSE otherwise.
1033 * Note: the iterator is defined to be bidirectional. That is,
1034 * any number of prev followed by any number of next, or
1035 * five versa, should leave the iterator at the same item:
1036 * prev * n, next * n = next * n, prev * n
1038 * The iterator has a notion of an out-of-order, special item,
1039 * which sits at the start of the list. This is used in
1040 * LVS_ICON, and LVS_SMALLICON mode to handle the focused item,
1041 * which needs to be first, as it may overlap other items.
1043 * The code is a bit messy because we have:
1044 * - a special item to deal with
1045 * - simple range, or composite range
1047 * If you find bugs, or want to add features, please make sure you
1048 * always check/modify *both* iterator_prev, and iterator_next.
1052 * This function iterates through the items in increasing order,
1053 * but prefixed by the special item, then -1. That is:

1934 * enough to compute only what's necessary. The function computes
1935 * the standard rectangles (BOUNDS, ICON, LABEL) plus a non-standard
1936 * one, the BOX rectangle. This rectangle is very cheap to compute,
1937 * and is guaranteed to contain all the other rectangles. Computing
1938 * the ICON rect is also cheap, but all the others are potentially
1939 * expensive. This gives an easy and effective optimization when
1940 * searching (like point inclusion, or rectangle intersection):
1941 * first test against the BOX, and if TRUE, test against the desired
1943 * If the function does not have all the necessary information
1944 * to computed the requested rectangles, will crash with a
1945 * failed assertion. This is done so we catch all programming
1946 * errors, given that the function is called only from our code.
1948 * We have the following 'special' meanings for a few fields:
1949 * * If LVIS_FOCUSED is set, we assume the item has the focus
