/* * ComboBoxEx control v2 (mod3) * * 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 * * TODO: * - All messages. * - All notifications. * * FIXME: * - should include "combo.h" * 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 CB_SETCURSEL. * 8. Add override for WNDPROC for the COMBO control. * * Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe), * 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; DWORD flags; /* WINE internal flags */ HFONT font; INT nb_items; /* Number of items */ 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 ID_CB_EDIT 1001 /* Height in pixels of control over the amount of the selected font */ #define CBE_EXTRA 3 /* Indent amount per MS documentation */ #define CBE_INDENT 10 /* Offset in pixels from left side for start of image or text */ #define CBE_STARTOFFSET 6 /* Offset between image and text */ #define CBE_SEP 4 #define COMBOEX_GetInfoPtr(hwnd) ((COMBOEX_INFO *)GetWindowLongA (hwnd, 0)) /* Things common to the entire DLL */ static ATOM ComboExInfo; static LRESULT WINAPI COMBOEX_EditWndProc (HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam); static LRESULT WINAPI COMBOEX_ComboWndProc (HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam); static void COMBOEX_DumpItem (CBE_ITEMDATA *item) { if (TRACE_ON(comboex)){ TRACE("item %p - mask=%08x, pszText=%p, cchTM=%d, iImage=%d\n", item, item->mask, item->pszText, item->cchTextMax, item->iImage); TRACE("item %p - iSelectedImage=%d, iOverlay=%d, iIndent=%d, lParam=%08lx\n", item, item->iSelectedImage, item->iOverlay, item->iIndent, item->lParam); if ((item->mask & CBEIF_TEXT) && item->pszText) TRACE("item %p - pszText=%s\n", item, debugstr_w((const WCHAR *)item->pszText)); } } static void COMBOEX_DumpInput (COMBOBOXEXITEMA *input, BOOL true_for_w) { if (TRACE_ON(comboex)){ TRACE("input - mask=%08x, iItem=%d, pszText=%p, cchTM=%d, iImage=%d\n", input->mask, input->iItem, input->pszText, input->cchTextMax, input->iImage); if ((input->mask & CBEIF_TEXT) && input->pszText) { if (true_for_w) TRACE("input - pszText=<%s>\n", debugstr_w((const WCHAR *)input->pszText)); else TRACE("input - pszText=<%s>\n", debugstr_a((const char *)input->pszText)); } TRACE("input - iSelectedImage=%d, iOverlay=%d, iIndent=%d, lParam=%08lx\n", input->iSelectedImage, input->iOverlay, input->iIndent, input->lParam); } } inline static LRESULT COMBOEX_Forward (HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) { COMBOEX_INFO *infoPtr = COMBOEX_GetInfoPtr (hwnd); FIXME("(0x%x 0x%x 0x%lx): stub\n", uMsg, wParam, lParam); if (infoPtr->hwndCombo) return SendMessageA (infoPtr->hwndCombo, uMsg, wParam, lParam); return 0; } static INT COMBOEX_Notify (COMBOEX_INFO *infoPtr, INT code, NMHDR *hdr) { hdr->idFrom = GetDlgCtrlID (infoPtr->hwndSelf); hdr->hwndFrom = infoPtr->hwndSelf; hdr->code = code; return SendMessageA (GetParent(infoPtr->hwndSelf), WM_NOTIFY, 0, (LPARAM)hdr); } static void COMBOEX_GetComboFontSize (COMBOEX_INFO *infoPtr, SIZE *size) { HFONT nfont, ofont; HDC mydc; mydc = GetDC (0); /* why the entire screen????
