/* * TODO <------------- * 1. The following extended styles need to be implemented, use will * result in a FIXME: * CBES_EX_NOEDITIMAGEINDENT * CBES_EX_PATHWORDBREAKPROC * CBES_EX_NOSIZELIMIT * CBES_EX_CASESENSITIVE * 2. None of the following callback items are implemented. Therefor * no CBEN_GETDISPINFO notifies are issued. Use in either CBEM_INSERTITEM * or CBEM_SETITEM will result in a FIXME: * LPSTR_TEXTCALLBACK * I_IMAGECALLBACK * I_INDENTCALLBACK * 3. No use is made of the iOverlay image. * 4. Notify CBEN_DRAGBEGIN is not implemented. */ /* * ComboBoxEx control v2 (mod6) * * Copyright 1998, 1999 Eric Kohl * * NOTES * This is just a dummy control. An author is needed! Any volunteers? * I will only improve this control once in a while. * Eric * * Changes Guy Albertelli * v1 Implemented messages: CB_SETITEMHEIGHT, WM_WINDOWPOSCHANGING, * WM_DRAWITEM, and WM_MEASUREITEM. Fixed WM_CREATE. Fixed height * of window rect reported fixing rebar control. * v2 * 1. Rewrite of WM_Create for own created EDIT control. Also try to * generate message sequence similar to native DLL. * 2. Handle case where CBEM_SETITEM is called to display data in EDIT * Control. * 3. Add override for WNDPROC for the EDIT control (reqed for VK_RETURN). * 4. Dump input data for things using COMBOBOXEXITEM{A|W}. * 5. Handle positioning EDIT control based on whether icon present. * 6. Make InsertItemA use InsertItemW, and store all data in ..W form. * 7. Implement CBEM_DELETEITEM, CBEM_GETITEM{A|W}, CB_SETCURSEL, * CBEM_{GET|SET}UNICODEFORMAT. * 8. Add override for WNDPROC for the COMBO control. * 9. Support extended style CBES_EX_NOEDITIMAGE and warn others are not * supported. * 10. Implement CB_FINDSTRINGEXACT in both the Combo and ComboEx window * procs to match the items. This eliminates dup entries in the listbox. * * mod 4 * 1. Implemented CBN_SELCHANGE, CBN_KILLFOCUS, and CBN_SELENDOK. * 2. Fix putting text in CBEN_ENDEDIT notifies for CBN_DROPDOWN case. * 3. Lock image selected status to focus state of edit control if * edit control exists. Mimics native actions. * 4. Implemented WM_SETFOCUS in EditWndProc to track status of * focus for 3 above. * 5. The LBN_SELCHANGE is just for documentation purposes. * * mod 5 * 1. Add support for CB_GETITEMDATA to a Comboex. Returns the LPARAM * passed during insert of item. * 2. Remember selected item and don't issue CB_SETCURSEL unless needed. * 3. Add initial support for WM_NCCREATE to remove unwanted window styles * (Currently just WS_VSCROLL and WS_HSCROLL, but probably should be * more.) * 4. Improve some traces. * 5. Add support for CB_SETITEMDATA sets LPARAM value from item. * * mod 6 * 1. Add support for WM_NOTIFYFORMAT (both incoming and outgoing) and do * WM_NOTIFY correctly based on results. * 2. Fix memory leaks of text strings in COMBOEX_WM_DELETEITEM. * 3. Add routines to handle special cases of NMCBEENDEDIT and NMCOMBOXEX * so translation to ANSI is done correctly. * 4. Fix some issues with COMBOEX_DrawItem. * * Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe), * WinRAR, and IE 4.0. * */ #include #include "winbase.h" #include "commctrl.h" #include "debugtools.h" #include "wine/unicode.h" DEFAULT_DEBUG_CHANNEL(comboex); /* * The following is necessary for the test done in COMBOEX_DrawItem * to determine whether to dump out the DRAWITEM structure or not. */ DECLARE_DEBUG_CHANNEL(message); /* Item structure */ typedef struct { VOID *next; UINT mask; LPWSTR pszText; int cchTextMax; int iImage; int iSelectedImage; int iOverlay; int iIndent; LPARAM lParam; } CBE_ITEMDATA; /* ComboBoxEx structure */ typedef struct { HIMAGELIST himl; HWND hwndSelf; /* my own hwnd */ HWND hwndCombo; HWND hwndEdit; WNDPROC prevEditWndProc; /* previous Edit WNDPROC value */ WNDPROC prevComboWndProc; /* previous Combo WNDPROC value */ DWORD dwExtStyle; INT selected; /* index of selected item */ DWORD flags; /* WINE internal flags */ HFONT hDefaultFont; HFONT font; INT nb_items; /* Number of items */ BOOL bUnicode; /* TRUE if this window is Unicode */ BOOL NtfUnicode; /* TRUE if parent wants notify in Unicode */ CBE_ITEMDATA *edit; /* item data for edit item */ CBE_ITEMDATA *items; /* Array of items */ } COMBOEX_INFO; /* internal flags in the COMBOEX_INFO structure */ #define WCBE_ACTEDIT 0x00000001 /* Edit active i.e. * CBEN_BEGINEDIT issued * but CBEN_ENDEDIT{A|W} * not yet issued. */ #define WCBE_EDITCHG 0x00000002 /* Edit issued EN_CHANGE */ #define WCBE_EDITFOCUSED 0x00000004 /* Edit control has focus */ #define ID_CB_EDIT 1001 /* * Special flag set in DRAWITEMSTRUCT itemState field.
