我有以下代码将窗口处理程序从 OpenCV 窗口传递给 win32 处理程序,因此我可以将从相机抓取的图像显示到屏幕上,并且图像将显示为我的主 API 的子窗口。但问题是当我想在我的程序中添加一个工具栏时,图像窗口处理程序出现在工具栏的顶部。我该如何解决这个问题?
//create a window and set the handler from openCV to win32
cv::namedWindow("test",cv::WINDOW_AUTOSIZE);
hWnd2 = (HWND) cvGetWindowHandle("test");
hParent = ::GetParent(hWnd2);
::SetParent(hWnd2, hWnd);
::ShowWindow(hParent, SW_HIDE);
_liveCapturing=true;
lastPicNr = 0;
SetWindowTextW(hStatus, L"Live Capturing ... ");
if(FullScreen()){
::ShowWindow(hWnd, SW_MAXIMIZE);
}
工具栏代码:
HWND CreateToolbar(HWND hwnd){
HWND hTbar = CreateWindowEx(0, TOOLBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE | CCS_TOP , 0, 0, 0, 0, hwnd, (HMENU)12, GetModuleHandle(NULL), NULL);
SendMessage(hTbar, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
TBBUTTON tbb[3];
TBADDBITMAP tbab;
tbab.hInst = HINST_COMMCTRL;
tbab.nID = IDB_STD_SMALL_COLOR;
SendMessage(hTbar, TB_ADDBITMAP, 0, (LPARAM)&tbab);
return hTbar;
}
