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_ERASEBKGND: forward this message to the parent window if the bkgnd
41 * -- WM_WINDOWPOSCHANGED: arrange the list items if the current view is icon
42 * or small icon and the LVS_AUTOARRANGE style is specified.
47 * -- Hot item handling, mouse hovering
48 * -- Workareas support
53 * -- Expand large item in ICON mode when the cursor is flying over the icon or text.
54 * -- Support CustomDraw options for _WIN32_IE >= 0x560 (see NMLVCUSTOMDRAW docs).
55 * -- LVA_SNAPTOGRID not implemented
56 * -- LISTVIEW_ApproximateViewRect partially implemented
57 * -- LISTVIEW_[GS]etColumnOrderArray stubs
58 * -- LISTVIEW_SetColumnWidth ignores header images & bitmap
59 * -- LISTVIEW_SetIconSpacing is incomplete
60 * -- LISTVIEW_SortItems is broken
61 * -- LISTVIEW_StyleChanged doesn't handle some changes too well
64 * -- LISTVIEW_GetNextItem needs to be rewritten. It is currently
65 * linear in the number of items in the list, and this is
66 * unacceptable for large lists.
67 * -- in sorted mode, LISTVIEW_InsertItemT sorts the array,
68 * instead of inserting in the right spot
69 * -- we should keep an ordered array of coordinates in iconic mode
70 * this would allow to frame items (iterator_frameditems),
71 * and find nearest item (LVFI_NEARESTXY) a lot more efficiently
79 * -- LVIS_ACTIVATING (not currently supported by comctl32.dll version 6.0)
86 * -- LVS_NOSCROLL (see Q137520)
87 * -- LVS_SORTASCENDING, LVS_SORTDESCENDING
89 * -- LVS_TYPESTYLEMASK
92 * -- LVS_EX_BORDERSELECT
95 * -- LVS_EX_HEADERDRAGDROP
98 * -- LVS_EX_MULTIWORKAREAS
99 * -- LVS_EX_ONECLICKACTIVATE
101 * -- LVS_EX_SIMPLESELECT
102 * -- LVS_EX_TRACKSELECT
103 * -- LVS_EX_TWOCLICKACTIVATE
104 * -- LVS_EX_UNDERLINECOLD
105 * -- LVS_EX_UNDERLINEHOT
108 * -- LVN_BEGINSCROLL, LVN_ENDSCROLL
111 * -- LVN_MARQUEEBEGIN
118 * -- LVM_CANCELEDITLABEL
119 * -- LVM_ENABLEGROUPVIEW
120 * -- LVM_GETBKIMAGE, LVM_SETBKIMAGE
121 * -- LVM_GETGROUPINFO, LVM_SETGROUPINFO
122 * -- LVM_GETGROUPMETRICS, LVM_SETGROUPMETRICS
123 * -- LVM_GETINSERTMARK, LVM_SETINSERTMARK
124 * -- LVM_GETINSERTMARKCOLOR, LVM_SETINSERTMARKCOLOR
125 * -- LVM_GETINSERTMARKRECT
126 * -- LVM_GETNUMBEROFWORKAREAS
127 * -- LVM_GETOUTLINECOLOR, LVM_SETOUTLINECOLOR

153 * -- ListView_GetTextBkColor
154 * -- ListView_GetUnicodeFormat, ListView_SetUnicodeFormat
155 * -- ListView_GetWorkAreas, ListView_SetWorkAreas
156 * -- ListView_SortItemsEx
161 * Known differences in message stream from native control (not known if
162 * these differences cause problems):
163 * LVM_INSERTITEM issues LVM_SETITEMSTATE and LVM_SETITEM in certain cases.
164 * LVM_SETITEM does not always issue LVN_ITEMCHANGING/LVN_ITEMCHANGED.
165 * WM_CREATE does not issue WM_QUERYUISTATE and associated registry
166 * processing for "USEDOUBLECLICKTIME".

1010 * ITERATOR DOCUMENTATION
1012 * The iterator functions allow for easy, and convenient iteration
1013 * over items of interest in the list. Typically, you create a
1014 * iterator, use it, and destroy it, as such:
1017 * iterator_xxxitems(&i, ...);
1018 * while (iterator_{prev,next}(&i)
1020 * //code which uses i.nItem
1022 * iterator_destroy(&i);
1024 * where xxx is either: framed, or visible.
1025 * Note that it is important that the code destroys the iterator
1026 * after it's done with it, as the creation of the iterator may
1027 * allocate memory, which thus needs to be freed.
1029 * You can iterate both forwards, and backwards through the list,
1030 * by using iterator_next or iterator_prev respectively.
1032 * Lower numbered items are draw on top of higher number items in
1033 * LVS_ICON, and LVS_SMALLICON (which are the only modes where
1034 * items may overlap). So, to test items, you should use
1036 * which lists the items top to bottom (in Z-order).
1037 * For drawing items, you should use
1039 * which lists the items bottom to top (in Z-order).
1040 * If you keep iterating over the items after the end-of-items
1041 * marker (-1) is returned, the iterator will start from the
1042 * beginning. Typically, you don't need to test for -1,
1043 * because iterator_{next,prev} will return TRUE if more items
1044 * are to be iterated over, or FALSE otherwise.
1046 * Note: the iterator is defined to be bidirectional. That is,
1047 * any number of prev followed by any number of next, or
1048 * five versa, should leave the iterator at the same item:
1049 * prev * n, next * n = next * n, prev * n
1051 * The iterator has a notion of an out-of-order, special item,
1052 * which sits at the start of the list. This is used in
1053 * LVS_ICON, and LVS_SMALLICON mode to handle the focused item,
1054 * which needs to be first, as it may overlap other items.
1056 * The code is a bit messy because we have:
1057 * - a special item to deal with
1058 * - simple range, or composite range
1060 * If you find bugs, or want to add features, please make sure you
1061 * always check/modify *both* iterator_prev, and iterator_next.
1065 * This function iterates through the items in increasing order,
1066 * but prefixed by the special item, then -1. That is:

1884 * the standard rectangles (BOUNDS, ICON, LABEL) plus a non-standard
1885 * one, the BOX rectangle. This rectangle is very cheap to compute,
1886 * and is guaranteed to contain all the other rectangles. Computing
1887 * the ICON rect is also cheap, but all the others are potentially
1888 * expensive. This gives an easy and effective optimization when
1889 * searching (like point inclusion, or rectangle intersection):
1890 * first test against the BOX, and if TRUE, test against the desired
1892 * If the function does not have all the necessary information
1893 * to computed the requested rectangles, will crash with a
1894 * failed assertion. This is done so we catch all programming
1895 * errors, given that the function is called only from our code.
1897 * We have the following 'special' meanings for a few fields:
1898 * * If LVIS_FOCUSED is set, we assume the item has the focus
1899 * This is important in ICON mode, where it might get a larger
