28 * This code was audited for completeness against the documented features
29 * of Comctl32.dll version 6.0 on May. 20, 2005, by James Hawkins.
31 * Unless otherwise noted, we believe this code to be complete, as per
32 * the specification mentioned above.
33 * If you discover missing features, or bugs, please note them below.
37 * Default Message Processing
38 * -- WM_CREATE: create the icon and small icon image lists at this point only if
39 * the LVS_SHAREIMAGELISTS style is not specified.
40 * -- WM_WINDOWPOSCHANGED: arrange the list items if the current view is icon
41 * or small icon and the LVS_AUTOARRANGE style is specified.
46 * -- Hot item handling, mouse hovering
47 * -- Workareas support
52 * -- Expand large item in ICON mode when the cursor is flying over the icon or text.
53 * -- Support CustomDraw options for _WIN32_IE >= 0x560 (see NMLVCUSTOMDRAW docs).
54 * -- LVA_SNAPTOGRID not implemented
55 * -- LISTVIEW_ApproximateViewRect partially implemented
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)
82 * -- LVS_NOSCROLL (see Q137520)
86 * -- LVS_EX_BORDERSELECT
90 * -- LVS_EX_MULTIWORKAREAS
92 * -- LVS_EX_SIMPLESELECT
93 * -- LVS_EX_TWOCLICKACTIVATE
94 * -- LVS_EX_UNDERLINECOLD
95 * -- LVS_EX_UNDERLINEHOT
98 * -- LVN_BEGINSCROLL, LVN_ENDSCROLL
105 * -- LVM_ENABLEGROUPVIEW
106 * -- LVM_GETBKIMAGE, LVM_SETBKIMAGE
107 * -- LVM_GETGROUPINFO, LVM_SETGROUPINFO
108 * -- LVM_GETGROUPMETRICS, LVM_SETGROUPMETRICS
109 * -- LVM_GETINSERTMARK, LVM_SETINSERTMARK
110 * -- LVM_GETINSERTMARKCOLOR, LVM_SETINSERTMARKCOLOR
111 * -- LVM_GETINSERTMARKRECT
112 * -- LVM_GETNUMBEROFWORKAREAS
113 * -- LVM_GETOUTLINECOLOR, LVM_SETOUTLINECOLOR
114 * -- LVM_GETSELECTEDCOLUMN, LVM_SETSELECTEDCOLUMN
115 * -- LVM_GETISEARCHSTRINGW, LVM_GETISEARCHSTRINGA
116 * -- LVM_GETTILEINFO, LVM_SETTILEINFO
117 * -- LVM_GETTILEVIEWINFO, LVM_SETTILEVIEWINFO
118 * -- LVM_GETWORKAREAS, LVM_SETWORKAREAS
119 * -- LVM_HASGROUP, LVM_INSERTGROUP, LVM_REMOVEGROUP, LVM_REMOVEALLGROUPS
120 * -- LVM_INSERTGROUPSORTED
121 * -- LVM_INSERTMARKHITTEST
122 * -- LVM_ISGROUPVIEWENABLED
124 * -- LVM_MOVEITEMTOGROUP
126 * -- LVM_SETTILEWIDTH
130 * -- ListView_GetHoverTime, ListView_SetHoverTime
131 * -- ListView_GetISearchString
132 * -- ListView_GetNumberOfWorkAreas
133 * -- ListView_GetWorkAreas, ListView_SetWorkAreas
138 * Known differences in message stream from native control (not known if
139 * these differences cause problems):
140 * LVM_INSERTITEM issues LVM_SETITEMSTATE and LVM_SETITEM in certain cases.
141 * LVM_SETITEM does not always issue LVN_ITEMCHANGING/LVN_ITEMCHANGED.
142 * WM_CREATE does not issue WM_QUERYUISTATE and associated registry
143 * processing for "USEDOUBLECLICKTIME".

1113 * ITERATOR DOCUMENTATION
1115 * The iterator functions allow for easy, and convenient iteration
1116 * over items of interest in the list. Typically, you create a
1117 * iterator, use it, and destroy it, as such:
1120 * iterator_xxxitems(&i, ...);
1121 * while (iterator_{prev,next}(&i)
1123 * //code which uses i.nItem
1125 * iterator_destroy(&i);
1127 * where xxx is either: framed, or visible.
1128 * Note that it is important that the code destroys the iterator
1129 * after it's done with it, as the creation of the iterator may
1130 * allocate memory, which thus needs to be freed.
1132 * You can iterate both forwards, and backwards through the list,
1133 * by using iterator_next or iterator_prev respectively.
1135 * Lower numbered items are draw on top of higher number items in
1136 * LVS_ICON, and LVS_SMALLICON (which are the only modes where
1137 * items may overlap). So, to test items, you should use
1139 * which lists the items top to bottom (in Z-order).
1140 * For drawing items, you should use
1142 * which lists the items bottom to top (in Z-order).
1143 * If you keep iterating over the items after the end-of-items
1144 * marker (-1) is returned, the iterator will start from the
1145 * beginning. Typically, you don't need to test for -1,
1146 * because iterator_{next,prev} will return TRUE if more items
1147 * are to be iterated over, or FALSE otherwise.
1149 * Note: the iterator is defined to be bidirectional. That is,
1150 * any number of prev followed by any number of next, or
1151 * five versa, should leave the iterator at the same item:
1152 * prev * n, next * n = next * n, prev * n
1154 * The iterator has a notion of an out-of-order, special item,
1155 * which sits at the start of the list. This is used in
1156 * LVS_ICON, and LVS_SMALLICON mode to handle the focused item,
1157 * which needs to be first, as it may overlap other items.
1159 * The code is a bit messy because we have:
1160 * - a special item to deal with
1161 * - simple range, or composite range
1163 * If you find bugs, or want to add features, please make sure you
1164 * always check/modify *both* iterator_prev, and iterator_next.

2140 * DESCRIPTION: [INTERNAL]
2141 * Compute the rectangles of an item. This is to localize all
2142 * the computations in one place. If you are not interested in some
2143 * of these values, simply pass in a NULL -- the function is smart
2144 * enough to compute only what's necessary. The function computes
2145 * the standard rectangles (BOUNDS, ICON, LABEL) plus a non-standard
2146 * one, the BOX rectangle. This rectangle is very cheap to compute,
2147 * and is guaranteed to contain all the other rectangles. Computing
2148 * the ICON rect is also cheap, but all the others are potentially
2149 * expensive. This gives an easy and effective optimization when
2150 * searching (like point inclusion, or rectangle intersection):
2151 * first test against the BOX, and if TRUE, test against the desired
2153 * If the function does not have all the necessary information
2154 * to computed the requested rectangles, will crash with a
2155 * failed assertion. This is done so we catch all programming
2156 * errors, given that the function is called only from our code.
2158 * We have the following 'special' meanings for a few fields:
2159 * * If LVIS_FOCUSED is set, we assume the item has the focus
2160 * This is important in ICON mode, where it might get a larger
2161 * then usual rectangle
2163 * Please note that subitem support works only in REPORT mode.
