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

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