This fixes icons that should be drawn transparently not showing as such until window gets repainted. For example, hidden shell folders that are not drawn transparently until the filebrowser window is resized... CORE-16722

|
|
* Default Message Processing
|
|
* -- WM_CREATE: create the icon and small icon image lists at this point only if
|
|
* the LVS_SHAREIMAGELISTS style is not specified.
|
|
* -- WM_WINDOWPOSCHANGED: arrange the list items if the current view is icon

* Bugs
|
|
* -- Expand large item in ICON mode when the cursor is flying over the icon or text.
|
|
* -- Support CustomDraw options for _WIN32_IE >= 0x560 (see NMLVCUSTOMDRAW docs).
|
|
* -- LVA_SNAPTOGRID not implemented
|
|
* -- LISTVIEW_ApproximateViewRect partially implemented
|
|
* -- 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.
|
|
* -- if list is sorted by item text LISTVIEW_InsertItemT could use
|
|
* binary search to calculate item index (e.g. DPA_Search()).
|
|
* This requires sorted state to be reliably tracked in item modifiers.
|
|
* -- we should keep an ordered array of coordinates in iconic mode.
|
|
* This would allow framing items (iterator_frameditems),
|
|
* and finding the nearest item (LVFI_NEARESTXY) a lot more efficiently.

/***
|
|
* ITERATOR DOCUMENTATION
|
|
*
|
|
* The iterator functions allow for easy, and convenient iteration
|
|
* over items of interest in the list. Typically, you create an
|
|
* 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 an 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.
|
|

* LISTVIEW_ProcessLetterKeys
|
|
*
|
|
* 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
|
|
*
|
|
* RETURNS
|
|
*
|
|
* Zero.
|
|
*
|
|
* BUGS
|
|
*
|
|
* - The current implementation has a list of characters it will
|
|
* accept and it ignores everything 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.

* the standard rectangles (BOUNDS, ICON, LABEL) plus a non-standard

* one, the BOX rectangle. This rectangle is very cheap to compute,

|
* and is guaranteed to contain all the other rectangles. Computing

|
* the ICON rect is also cheap, but all the others are potentially
|
|
* expensive. This gives an easy and effective optimization when
|
|
* searching (like point inclusion, or rectangle intersection):
|
|
* first test against the BOX, and if TRUE, test against the desired
|
|
* rectangle.
|
|
* If the function does not have all the necessary information
|
|
* to computed the requested rectangles, will crash with a
|
|
* failed assertion. This is done so we catch all programming

|
* errors, given that the function is called only from our code.

* This is important in ICON mode, where it might get a larger
