/* * ComboBoxEx control * * 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 * 1. Implemented message CB_SETITEMHEIGHT * 2. Implemented message WM_WINDOWPOSCHANGING * 3. Implemented message WM_MEASUREITEM * 4. Add code to WM_CREATE processing to set font of COMBOBOX and * issue the CB_SETITEMHEIGHT to start the correct sizing process. * The above 4 changes allow the window rect for the comboboxex * to be set properly, which in turn allows the height of the * rebar control it *may* be imbeded in to be correct. * 5. Rewrite CBEM_INSERTITEMA to save the information. * 6. Implemented message WM_DRAWITEM. The code will handle images * but not "overlays" yet. * 7. Fixed code in CBEM_SETIMAGELIST to resize control. * 8. Add debugging code. * * Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe) * */ #include "winbase.h" #include "wine/winestring.h" #include "commctrl.h" #include "debugtools.h" #include "wine/unicode.h" DEFAULT_DEBUG_CHANNEL(comboex); 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 hwndCombo; DWORD dwExtStyle; HFONT font; INT nb_items; /* Number of items */ CBE_ITEMDATA *items; /* Array of items */ } COMBOEX_INFO; #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(wndPtr) ((COMBOEX_INFO *)GetWindowLongA (hwnd, 0)) 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); } } 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 void COMBOEX_ReSize (HWND hwnd, COMBOEX_INFO *infoPtr) { HFONT nfont, ofont; HDC mydc; SIZE mysize; UINT cy; IMAGEINFO iinfo; mydc = GetDC (0); /* why the entire screen???? */ nfont = SendMessageA (infoPtr->hwndCombo, WM_GETFONT, 0, 0); ofont = (HFONT) SelectObject (mydc, nfont); GetTextExtentPointA (mydc, "A", 1, &mysize); SelectObject (mydc, ofont); ReleaseDC (0, mydc); cy = mysize.cy + CBE_EXTRA; if (infoPtr->himl) { ImageList_GetImageInfo(infoPtr->himl, 0, &iinfo); cy = max (iinfo.rcImage.bottom - iinfo.rcImage.top, cy); } TRACE("selected font hwnd=%08x, height=%d\n", nfont, cy); SendMessageA (hwnd, CB_SETITEMHEIGHT, (WPARAM) -1, (LPARAM) cy); if (infoPtr->hwndCombo) SendMessageA (infoPtr->hwndCombo, CB_SETITEMHEIGHT, (WPARAM) 0, (LPARAM) cy); } /* *** CBEM_xxx message support *** */ /* << COMBOEX_DeleteItem >> */ inline static LRESULT COMBOEX_GetComboControl (HWND hwnd, WPARAM wParam, LPARAM lParam) { COMBOEX_INFO *infoPtr = COMBOEX_GetInfoPtr (hwnd); TRACE("\n"); return (LRESULT)infoPtr->hwndCombo; } inline static LRESULT COMBOEX_GetEditControl (HWND hwnd, WPARAM wParam, LPARAM lParam) { COMBOEX_INFO *infoPtr = COMBOEX_GetInfoPtr (hwnd); if ((GetWindowLongA (hwnd, GWL_STYLE) & CBS_DROPDOWNLIST) != CBS_DROPDOWN) return 0; TRACE("-- 0x%x\n", GetDlgItem (infoPtr->hwndCombo, ID_CB_EDIT)); return (LRESULT)GetDlgItem (infoPtr->hwndCombo, ID_CB_EDIT); } inline static LRESULT COMBOEX_GetExtendedStyle (HWND hwnd, WPARAM wParam, LPARAM lParam) { COMBOEX_INFO *infoPtr = COMBOEX_GetInfoPtr (hwnd); return (LRESULT)infoPtr->dwExtStyle; } inline static LRESULT COMBOEX_GetImageList (HWND hwnd, WPARAM wParam, LPARAM lParam) { COMBOEX_INFO *infoPtr = COMBOEX_GetInfoPtr (hwnd); TRACE("(0x%08x 0x%08lx)\n", wParam, lParam); return (LRESULT)infoPtr->himl; } /* << COMBOEX_GetItemA >> */ /* << COMBOEX_GetItemW >> */ /* << COMBOEX_GetUniCodeFormat >> */ /* << COMBOEX_HasEditChanged >> */ static LRESULT COMBOEX_InsertItemA (HWND hwnd, WPARAM wParam, LPARAM lParam) { COMBOEX_INFO *infoPtr = COMBOEX_GetInfoPtr (hwnd); COMBOBOXEXITEMA *cit = (COMBOBOXEXITEMA *) lParam; INT index; CBE_ITEMDATA *item; /* get real index of item to insert */ index = cit->iItem; if (index == -1) index = infoPtr->nb_items; if (index > infoPtr->nb_items) index = infoPtr->nb_items; /* get space and chain it in */ item = (CBE_ITEMDATA *)COMCTL32_Alloc (sizeof (CBE_ITEMDATA)); item->next = NULL; item->pszText = NULL; /* locate position to insert new item in */ if (index == infoPtr->nb_items) { /* fast path for iItem = -1 */ item->next = infoPtr->items; infoPtr->items = item; } else { int i = infoPtr->nb_items-1; CBE_ITEMDATA *moving = infoPtr->items; while (i > index && moving) { moving = (CBE_ITEMDATA *)moving->next; } if (!moving) { FIXME("COMBOBOXEX item structures broken.
