2 * TODO <-------------
3 * 1. The following extended styles need to be implemented, use will
4 * result in a FIXME:
5 * CBES_EX_NOEDITIMAGEINDENT
6 * CBES_EX_PATHWORDBREAKPROC
7 * CBES_EX_NOSIZELIMIT
8 * CBES_EX_CASESENSITIVE
9 * 2. None of the following callback items are implemented. Therefor
10 * no CBEN_GETDISPINFO notifies are issued. Use in either CBEM_INSERTITEM
11 * or CBEM_SETITEM will result in a FIXME:
12 * LPSTR_TEXTCALLBACK
13 * I_IMAGECALLBACK
14 * I_INDENTCALLBACK
15 * 3. No use is made of the iOverlay image.
16 * 4. Notify CBEN_DRAGBEGIN is not implemented.

21 * ComboBoxEx control v2 (mod6)
22 *
23 * Copyright 1998, 1999 Eric Kohl
24 *
25 * NOTES
26 * This is just a dummy control. An author is needed! Any volunteers?
27 * I will only improve this control once in a while.
28 * Eric <ekohl@abo.rhein-zeitung.de>
29 *
30
31 * Changes Guy Albertelli <galberte@neo.lrun.com>
32 * v1 Implemented messages: CB_SETITEMHEIGHT, WM_WINDOWPOSCHANGING,
33 * WM_DRAWITEM, and WM_MEASUREITEM. Fixed WM_CREATE. Fixed height
34 * of window rect reported fixing rebar control.
35 * v2
36 * 1. Rewrite of WM_Create for own created EDIT control. Also try to
37 * generate message sequence similar to native DLL.
38 * 2. Handle case where CBEM_SETITEM is called to display data in EDIT
39 * Control.
40 * 3. Add override for WNDPROC for the EDIT control (reqed for VK_RETURN).
41 * 4. Dump input data for things using COMBOBOXEXITEM{A|W}.
42 * 5. Handle positioning EDIT control based on whether icon present.
43 * 6. Make InsertItemA use InsertItemW, and store all data in ..W form.
44 * 7. Implement CBEM_DELETEITEM, CBEM_GETITEM{A|W}, CB_SETCURSEL,
45 * CBEM_{GET|SET}UNICODEFORMAT.
46 * 8. Add override for WNDPROC for the COMBO control.
47 * 9. Support extended style CBES_EX_NOEDITIMAGE and warn others are not
48 * supported.
49 * 10. Implement CB_FINDSTRINGEXACT in both the Combo and ComboEx window
50 * procs to match the items. This eliminates dup entries in the listbox.
51 *
52 * mod 4
53 * 1. Implemented CBN_SELCHANGE, CBN_KILLFOCUS, and CBN_SELENDOK.
54 * 2. Fix putting text in CBEN_ENDEDIT notifys for CBN_DROPDOWN case.
55 * 3. Lock image selected status to focus state of edit control if
56 * edit control exists. Mimics native actions.
57 * 4. Implemented WM_SETFOCUS in EditWndProc to track status of
58 * focus for 3 above.
59 * 5. The LBN_SELCHANGE is just for documentation purposes.
60 *
61 * mod 5
62 * 1. Add support for CB_GETITEMDATA to a Comboex. Returns the LPARAM
63 * passed during insert of item.
64 * 2. Remember selected item and don't issue CB_SETCURSEL unless needed.
65 * 3. Add initial support for WM_NCCREATE to remove unwanted window styles
66 * (Currently just WS_VSCROLL and WS_HSCROLL, but probably should be
67 * more.)
68 * 4. Improve some traces.
69 * 5. Add support for CB_SETITEMDATA sets LPARAM value from item.
70 *
71 * mod 6
72 * 1. Add support for WM_NOTIFYFORMAT (both incoming and outgoing) and do
73 * WM_NOTIFY correctly based on results.
74 * 2. Fix memory leaks of text strings in COMBOEX_WM_DELETEITEM.
75 * 3. Add routines to handle special cases of NMCBEENDEDIT and NMCOMBOXEX
76 * so translation to ANSI is done correctly.
77 * 4. Fix some issues with COMBOEX_DrawItem.
78 *
79 * Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe),
80 * WinRAR, and IE 4.0.
