最近项目需要在SmartPhone上实现一个HyperLink的功能,显然win32的控件里没有现成的,只有自己开发一个
首先注册一个窗口类
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
...{
…… if (!HyperLinkRegisterClass(hInstance)
...{ return FALSE;
}……
}ATOM HyperLinkRegisterClass(HINSTANCE hInstance)...{ WNDCLASS wndclass; wndclass.style = CS_HREDRAW | CS_VREDRAW ; wndclass.lpfnWndProc = HyperLinkWndProc; wndclass.cbClsExtra = 0; wndclass.cbWndExtra = 0; wndclass.hInstance = hInstance; wndclass.hIcon = NULL; wndclass.hCursor = LoadCursor (NULL, IDC_ARROW); //wndclass.hbrBackground = (HBRUSH) (COLOR_BTNFACE + 1) ; wndclass.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1); //wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH); wndclass.lpszMenuName = NULL; wndclass.lpszClassName = TEXT("CtlHyperLink"); return RegisterClass (&wndclass) ;}然后处理控件的各种消息达到自己想要的效果
LRESULT CALLBACK HyperLinkWndProc (HWND hwnd, UINT message,WPARAM wParam, LPARAM lParam)...{ LONG ID; switch (message) ...{ case WM_PAINT: ID= (LONG)GetWindowLong (hwnd, GWL_ID); for(int i=0;i<CAPTION_INDEX_LENGTH;i++) if(HYPERLINK_CAPTION_INDEX[i] == ID) ...{ pszText = HYPERLINK_CAPTION[i]; if(bHyperLinkSelect[i]) RenderHyperLink(hwnd,TRUE); else RenderHyperLink(hwnd,FALSE); } return 0 ; case WM_SETFOCUS: /**//*RenderHyperLink(hwnd,TRUE); */ ID= (LONG)GetWindowLong (hwnd, GWL_ID); for(int i=0;i<CAPTION_INDEX_LENGTH;i++) if(HYPERLINK_CAPTION_INDEX[i] == ID) ...{ bHyperLinkSelect[i] = TRUE; } InvalidateRect(hwnd, NULL, true); SendMessage(hwnd, WM_PAINT, GetWindowLong (hwnd, GWL_ID), (LPARAM) hwnd); return 0 ; case WM_KILLFOCUS: /**//*RenderHyperLink(hwnd,TRUE); */ ID= (LONG)GetWindowLong (hwnd, GWL_ID); for(int i=0;i<CAPTION_INDEX_LENGTH;i++) if(HYPERLINK_CAPTION_INDEX[i] == ID) ...{ bHyperLinkSelect[i] = FALSE; } InvalidateRect(hwnd, NULL, true); SendMessage(hwnd, WM_PAINT, GetWindowLong (hwnd, GWL_ID), (LPARAM) hwnd); return 0 ; case WM_KEYUP: if (wParam != VK_SPACE) break ;// fall through /**//*case WM_KEYUP: SendMessage (GetParent (hwnd), WM_COMMAND, GetWindowLong (hwnd, GWL_ID), (LPARAM) hwnd) ; return 0 ; case WM_KEYDOWN: SendMessage (GetParent (hwnd), WM_COMMAND, GetWindowLong (hwnd, GWL_ID), (LPARAM) hwnd) ; return 0 ;*/ //case WM_KEYDOWN: // return 0 ; case WM_LBUTTONUP : SendMessage (GetParent (hwnd), WM_COMMAND, GetWindowLong (hwnd, GWL_ID), (LPARAM) hwnd) ; return 0 ; } return DefWindowProc (hwnd, message, wParam, lParam) ;} int RenderHyperLink(HWND hwnd,BOOL bSelect)...{ LOGFONT ft; HFONT hFontNew, hFontOld; HBRUSH hBrush; HDC hdc; PAINTSTRUCT ps; RECT rect; GetClientRect (hwnd, &rect); hdc = BeginPaint (hwnd, &ps); hBrush = CreateSolidBrush (GetSysColor (COLOR_WINDOW)) ; hBrush = (HBRUSH) SelectObject (hdc, hBrush) ; FillRect(hdc,&rect,hBrush); memset(&ft, 0, sizeof(ft)); wcscpy(ft.lfFaceName, TEXT("宋体")); //fonttype ft.lfHeight = 16; //fontsize ft.lfUnderline = TRUE; hFontNew = CreateFontIndirect(&ft); hFontOld = (HFONT)SelectObject(hdc, hFontNew); if(bSelect) ...{ SetBkColor (hdc, GetSysColor (COLOR_WINDOW)); SetTextColor (hdc, (COLORREF)0x000000FF); } else ...{ SetBkColor (hdc, GetSysColor (COLOR_WINDOW)); SetTextColor (hdc, GetSysColor (COLOR_WINDOWTEXT)); } DrawText (hdc, pszText, -1, &rect, DT_SINGLELINE | DT_LEFT ); //SetWindowLong(hwnd,GWL_STYLE,WS_CAPTION); SelectObject(hdc, hFontOld); DeleteObject (SelectObject (hdc, hBrush)) ; EndPaint (hwnd, &ps) ; return 0;}最后,在RC编辑器里托一个Custom Control到Dialog上,在Class属性里填写CtlHyperLink
