27 * NOTES
28 *
29 * This code was audited for completeness against the documented features
30 * of Comctl32.dll version 6.0 on May. 20, 2005, by James Hawkins.
31 *
32 * Unless otherwise noted, we believe this code to be complete, as per
33 * the specification mentioned above.
34 * If you discover missing features, or bugs, please note them below.
35 *
36 * TODO:
37 *
38 * Default Message Processing
39 * -- WM_CREATE: create the icon and small icon image lists at this point only if
40 * the LVS_SHAREIMAGELISTS style is not specified.
41 * -- WM_WINDOWPOSCHANGED: arrange the list items if the current view is icon
42 * or small icon and the LVS_AUTOARRANGE style is specified.
43 * -- WM_TIMER
44 * -- WM_WININICHANGE
45 *
46 * Features
47 * -- Hot item handling, mouse hovering
48 * -- Workareas support
49 * -- Tilemode support
50 * -- Groups support
51 *
52 * Bugs
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_StyleChanged doesn't handle some changes too well
58 *
59 * Speedups
60 * -- LISTVIEW_GetNextItem needs to be rewritten. It is currently
61 * linear in the number of items in the list, and this is
62 * unacceptable for large lists.
63 * -- if list is sorted by item text LISTVIEW_InsertItemT could use
64 * binary search to calculate item index (e.g. DPA_Search()).
65 * This requires sorted state to be reliably tracked in item modifiers.
66 * -- we should keep an ordered array of coordinates in iconic mode.
67 * This would allow framing items (iterator_frameditems),
68 * and finding the nearest item (LVFI_NEARESTXY) a lot more efficiently.
69 *
70 * Flags
71 * -- LVIF_COLUMNS
72 * -- LVIF_GROUPID
73 *
74 * States
75 * -- LVIS_ACTIVATING (not currently supported by comctl32.dll version 6.0)
76 * -- LVIS_DROPHILITED
77 *
78 * Styles
79 * -- LVS_NOLABELWRAP
80 * -- LVS_NOSCROLL (see Q137520)
81 * -- LVS_ALIGNTOP
82 *
83 * Extended Styles
84 * -- LVS_EX_BORDERSELECT

1140 /***
1141 * ITERATOR DOCUMENTATION
1142 *
1143 * The iterator functions allow for easy, and convenient iteration
1144 * over items of interest in the list. Typically, you create an
1145 * iterator, use it, and destroy it, as such:
1146 * ITERATOR i;
1147 *
1148 * iterator_xxxitems(&i, ...);
1149 * while (iterator_{prev,next}(&i)
1150 * {
1151 * //code which uses i.nItem
1152 * }
1153 * iterator_destroy(&i);
1154 *
1155 * where xxx is either: framed, or visible.
1156 * Note that it is important that the code destroys the iterator
1157 * after it's done with it, as the creation of the iterator may
1158 * allocate memory, which thus needs to be freed.
1159 *
1160 * You can iterate both forwards, and backwards through the list,
1161 * by using iterator_next or iterator_prev respectively.
1162 *
1163 * Lower numbered items are draw on top of higher number items in
1164 * LVS_ICON, and LVS_SMALLICON (which are the only modes where
1165 * items may overlap). So, to test items, you should use
1166 * iterator_next
1167 * which lists the items top to bottom (in Z-order).
1168 * For drawing items, you should use
1169 * iterator_prev
1170 * which lists the items bottom to top (in Z-order).
1171 * If you keep iterating over the items after the end-of-items
1172 * marker (-1) is returned, the iterator will start from the
1173 * beginning. Typically, you don't need to test for -1,
1174 * because iterator_{next,prev} will return TRUE if more items
1175 * are to be iterated over, or FALSE otherwise.
1176 *
1177 * Note: the iterator is defined to be bidirectional. That is,
1178 * any number of prev followed by any number of next, or
1179 * five versa, should leave the iterator at the same item:
1180 * prev * n, next * n = next * n, prev * n
1181 *
1182 * The iterator has a notion of an out-of-order, special item,
1183 * which sits at the start of the list. This is used in
1184 * LVS_ICON, and LVS_SMALLICON mode to handle the focused item,
1185 * which needs to be first, as it may overlap other items.
1186 *
1187 * The code is a bit messy because we have:
1188 * - a special item to deal with
1189 * - simple range, or composite range
1190 * - empty range.
1191 * If you find bugs, or want to add features, please make sure you
1192 * always check/modify *both* iterator_prev, and iterator_next.

1813 * LISTVIEW_ProcessLetterKeys

1815 * Processes keyboard messages generated by pressing the letter keys

1817 * What this does is perform a case insensitive search from the
1818 * current position with the following quirks:
1819 * - If two chars or more are pressed in quick succession we search
1820 * for the corresponding string (e.g. 'abc').
1821 * - If there is a delay we wipe away the current search string and
1822 * restart with just that char.
1823 * - If the user keeps pressing the same character, whether slowly or
1824 * fast, so that the search string is entirely composed of this
1825 * character ('aaaaa' for instance), then we search for first item
1826 * that starting with that character.
1827 * - If the user types the above character in quick succession, then
1828 * we must also search for the corresponding string ('aaaaa'), and
1829 * go to that string if there is a match.
1830 *
1831 * PARAMETERS

1833 * [I] charCode : the character code, the actual character
1834 * [I] keyData : key data

1844 * ignore accentuated characters which seems to match what

2301 * first test against the BOX, and if TRUE, test against the desired
2302 * rectangle.
2303 * If the function does not have all the necessary information
2304 * to computed the requested rectangles, will crash with a
