OpenCV - Icon in Window
in [Win32 API]
|
From: Franz Bachler on 5 Nov 2009 11:35 Hello, I've created a program with OpenCV which show a JPG-Image in a Window: strcpy(szTemp, TEXT("Name of the Window")); (IplImage*) img = cvLoadImage(szTemp, 1); cvNamedWindow(szText, 0); cvShowImage(szText, img); cvWaitKey(0); cvDestroyWindow(szText); The Window has only a standard "Empty Window Icon" in the upper left corner. How can I put my own icon there? Greetings, Franz -- Franz Bachler, A-3250 Wieselburg E-Mail: fraba (at) gmx.at Homepage: http://members.aon.at/fraba oder http://home.pages.at/fraba

Yes. To add an icon in a dialogbox this works - but not with the OpenCV-Window SetClassLong( hWnd, GCL_HICON, (LONG) LoadIcon( GetModuleHandle(NULL), MAKEINTRESOURCE(ICO_NAMEICON) ) ); The HWND-Handle from the OpenCV-Window is from hWnd=(HWND) cvGetWindowHandle(szNameofWindow); Greetings, Franz

Hello, sorry but SendMessage(hWnd, WM_SETICON, (WPARAM) FALSE, (LONG) LoadIcon(GetModuleHandle(NULL), MAKEINTRESOURCE(ICO_NAME))); doesn't work. Greetings, Franz |
