* NOTES
|
|
*
|
|
* This code was audited for completeness against the documented features
|
|
* of Comctl32.dll version 6.0 on Oct. 21, 2002, by Dimitrie O. Paun.
|
|
*
|
|
* Unless otherwise noted, we believe this code to be complete, as per
|
|
* the specification mentioned above.
|
|
* If you discover missing features, or bugs, please note them below.
|
|
*
|
|
* TODO:
|
|
*
|
|
* Features
|
|
* -- Hot item handling, mouse hovering
|
|
* -- Workareas support
|
|
* -- Tilemode support
|
|
* -- Groups support
|
|
*
|
|
* Bugs
|
|
* -- Expand large item in ICON mode when the cursor is flying over the icon or text.
|
|
* -- Support CustonDraw options for _WIN32_IE >= 0x560 (see NMLVCUSTOMDRAW docs.
|
|
* -- in LISTVIEW_AddGroupSelection, we would send LVN_ODSTATECHANGED
|
|
* -- LVA_SNAPTOGRID not implemented
|
|
* -- LISTVIEW_ApproximateViewRect partially implemented
|
|
* -- LISTVIEW_[GS]etColumnOrderArray stubs
|
|
* -- LISTVIEW_SetColumnWidth ignores header images & bitmap
|
|
* -- LISTVIEW_SetIconSpacing is incomplete
|
|
* -- LISTVIEW_SortItems is broken
|
|
* -- LISTVIEW_StyleChanged doesn't handle some changes too well
|
|
*
|
|
* Speedups
|
|
* -- LISTVIEW_GetNextItem needs to be rewritten. It is currently
|
|
* linear in the number of items in the list, and this is
|
|
* unacceptable for large lists.
|
|
* -- in sorted mode, LISTVIEW_InsertItemT sorts the array,
|
|
* instead of inserting in the right spot
|
|
* -- we should keep an ordered array of coordinates in iconic mode
|
|
* this would allow to frame items (iterator_frameditems),
|
|
* and find nearest item (LVFI_NEARESTXY) a lot more efficiently

|
|
* Known differences in message stream from native control (not known if
|
|
* these differences cause problems):
|
|
* LVM_INSERTITEM issues LVM_SETITEMSTATE and LVM_SETITEM in certain cases.
|
|
* LVM_SETITEM does not always issue LVN_ITEMCHANGING/LVN_ITEMCHANGED.
|
|
* WM_CREATE does not issue WM_QUERYUISTATE and associated registry
|
|
* processing for "USEDOUBLECLICKTIME".

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

|
|
* Processes keyboard messages generated by pressing the letter keys

* on the keyboard.
|
|
* What this does is perform a case insensitive search from the
|
|
* current position with the following quirks:
|
|
* - If two chars or more are pressed in quick succession we search
|
|
* for the corresponding string (e.g. 'abc').
|
|
* - If there is a delay we wipe away the current search string and
|
|
* restart with just that char.
|
|
* - If the user keeps pressing the same character, whether slowly or
|
|
* fast, so that the search string is entirely composed of this
|
|
* character ('aaaaa' for instance), then we search for first item
|
|
* that starting with that character.
|
|
* - If the user types the above character in quick succession, then
|
|
* we must also search for the corresponding string ('aaaaa'), and
|
|
* go to that string if there is a match.
|
|
*
|
|
* PARAMETERS
|
|
* [I] hwnd : handle to the window
|
|
* [I] charCode : the character code, the actual character
|

* [I] keyData : key data

* BUGS
|
|
*
|
|
* - The current implementation has a list of characters it will
|
|
* accept and it ignores averything else. In particular it will
|
|
* ignore accentuated characters which seems to match what
|
|
* Windows does. But I'm not sure it makes sense to follow
|
|
* Windows there.
|
|
* - We don't sound a beep when the search fails.

* rectangle.

* If the function does not have all the necessary information
