Windows uses CEF embedded based on Chrome kernel browser Small example

CEF came out for a long time, the use is also very extensive, QQ inside a lot of places are embedded CEF browser (profile, Weibo, find ...) ), the online information is also quite a lot of, we can search to see.

The first is to download the CEF code compilation, through the inside of the two examples you can also follow the gourd painting scoop. Official: http://cefbuilds.com/

A very detailed explanation is recommended here: http://www.cnblogs.com/think/archive/2011/10/06/CEF-Introduce.html

The various "message" processing classes that overload CEF need to be overloaded when you need to handle them yourself or customize them, and you must override the corresponding virtual function to return the this pointer after overloading. It is estimated that there are these callback class object pointers internally, and that if you do not return this, the default is null, and the internal default set of mechanisms will be executed.

The overloads of the Cefapp class are then implemented, without the actual processing functionality, which is ignored here. 
When used, create a Win32 project and then modify the WinMain function:
<span style= "Font-family:microsoft yahei;font-size:12px;" >CefRefPtr<CCefHandler> g_handler;int apientry _tWinMain (hinstance hinstance, hinstance Hprev Instance, LPTSTR lpcmdline, int ncmdshow) {//TODO: Place code here. Cefmainargs Main_args (HINSTANCE); Cefrefptr<ccefappex> app (new Ccefappex); int exit_code = Cefexecuteprocess (Main_args, App.get ()); if (Exit_code >= 0) {return exit_code;} Cefsettings settings;settings.single_process = True;//settings.multi_threaded_message_loop = true; Cefinitialize (Main_args, Settings, App.get ()),//if (strcmd.size () = = 0) haccel hacceltable;//Initialize global string loadstring ( HINSTANCE, Ids_app_title, SzTitle, max_loadstring); LoadString (HInstance, Idc_cefdemo, Szwindowclass, max_loadstring); MyRegisterClass (HINSTANCE);//Execution of application initialization: if (! InitInstance (HINSTANCE, nCmdShow)) {return FALSE;} hacceltable = Loadaccelerators (hinstance, Makeintresource (Idc_cefdemo)); Cefrunmessageloop (); Cefshutdown (); RETUrn 0;} </span>
message processing mainly is to create, destroy CEF objects, the window size changes when the CEF window is notified, etc.:
<span style= "Font-family:microsoft yahei;font-size:12px;" >lresult CALLBACK WndProc (HWND hwnd, UINT message, WPARAM WPARAM, LPARAM LPARAM) {int wmid, wmevent; Paintstruct PS; HDC hdc;switch (message) {case Wm_create:{//http://blog.csdn.net/wongson/article/details/6210854g_handler=new Ccefhandler (L "www.qq.com"); Rect Rect;::getclientrect (hwnd, &rect); G_handler->createbrowser (hwnd, RECT); break;} Case wm_command:wmid = LoWord (wParam); wmevent = HiWord (WParam);//Analysis Menu selection: switch (wmid) {case Idm_exit:destroywindow (hwn d); break;default:break;} Break;case WM_PAINT:HDC = BeginPaint (hWnd, &ps);//TODO: Add any drawing code here ... EndPaint (HWnd, &ps); Break;case wm_size:{if (WParam = size_minimized | | NULL = = g_handler| | NULL = = G_handler->getbrowserhostwnd ()) break; HWND Hbrowserwnd=g_handler->getbrowserhostwnd (); RECT Rect;::getclientrect (hWnd, &rect);:: MoveWindow (Hbrowserwnd, Rect.left, Rect.top, Rect.right-rect.left, Rect.bottom-rect.top, TRUE); break;} Case Wm_close:{if (G_handler.get() &&!g_handler->isclosing ()) {wstring strurl=g_handler->getloadingurl (); Cefrefptr<cefbrowser> Pbrowser=g_handler->getbrowser (); if (Pbrowser.get ()) Pbrowser->gethost () CloseBrowser (TRUE);} break;} Default:break;} Return DefWindowProc (hWnd, message, WParam, LParam);} </span>
compile, run the program, a simple page came out, loading speed than ie that garbage much faster, the key is to ignore the compatibility issue. 


Finally remember to bring a lot of CEF DLL, this is necessary, if the webpage needs to play video, need to create a new plugins folder, put into the video playback plugin NPSWF32.dll.
CEF dynamic link libraries that need to be linked:
