ClientApp constructor runs several times?

[payalord]

Here is what I have:

Code: Select all

class ClientApp : public CefApp, public CefRenderProcessHandler, public CefBrowserProcessHandler {
public:
    ClientApp();
   ~ClientApp();
// ...

Code: Select all

ClientApp::ClientApp()
{
   Environment::Initialize();
}

ClientApp::~ClientApp()
{
   Environment::ShutDown();
}

void ClientApp::OnWebKitInitialized()
{
// ...

Code: Select all

class ClientHandler : public CefClient, public CefLifeSpanHandler {
public:
    ClientHandler();
// ...
virtual bool OnProcessMessageReceived(CefRefPtr<CefBrowser> browser, CefProcessId source_process, CefRefPtr<CefProcessMessage> message) OVERRIDE;
// ...

So I just noticed that the code in my Environment::Initialize() runs every time after OnProcessMessageReceived finishes it's work. Is it normal? While I'm using with this particular ClientHandler and ClientApp only 1 browser.

What does your GetBrowserProcessHandler implementation look like?

[payalord]

Code: Select all

   CefRefPtr<CefBrowserProcessHandler> GetBrowserProcessHandler() OVERRIDE
   {
      return this;
   }

But i found that it is not related to ClientApp object. I moved Environment::Initialize(); from ClientApp into main.cpp to WinMain function like this:

Code: Select all

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE, LPSTR, int nCmdShow)
{
    Environment::Initialize();
    // ... some code
    CefShutDown();
    return result;
}

And creating new browser window with different client handler called RequestClientHandler inside ClientHandler::OnProcessMessageReceived with CefBrowserHost::CreateBrowserSync function causing that the code of Environment::Initialize() running again. There is no other places other than first line of WinMain where this code must run. But how it can run twice then?

And yeah browser with CefBrowserHost::CreateBrowserSync and working fine. But i don't understand why WinMain runs again and how?

Is it possible that because new process/thread is created for new browser, that it runs separately WinMain again for itself by some reason?

Are you properly handling the sub process?

I'm using single executable and this is my main function:

Code: Select all

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE, LPSTR, int nCmdShow)
{
   Environment::Initialize();
   CefMainArgs main_args(hInstance);

    CefRefPtr<ClientApp> app(new ClientApp);

    // Execute the secondary process, if any.
    int exit_code = CefExecuteProcess( main_args, app.get(), NULL );
    if ( exit_code >= 0 ) {
        exit(exit_code);
    }

    // Register the window class.
    HWND hwnd = RegisterWindow(hInstance, nCmdShow);
    if ( hwnd == 0 ) {
        return 0;
    }

   tsks.SetParent(hwnd);

    RECT rect;
    GetClientRect(hwnd, &rect);

    CefSettings settings;
   settings.remote_debugging_port = 8080;
    CefInitialize( main_args, settings, app.get(), NULL );
    CefWindowInfo        info;
    CefBrowserSettings   b_settings;
    CefRefPtr<CefClient> client(new ClientHandler);
    g_handler = (ClientHandler *) client.get();
    //std::string path = "file://" + GetApplicationDir() + "/html/index.html";
   std::string path = "resource://html/index.html";
    CefRefPtr<CefCommandLine> command_line = CefCommandLine::GetGlobalCommandLine();

    if ( command_line->HasSwitch("url") ) {
        path = command_line->GetSwitchValue("url");
    }

    info.SetAsChild(hwnd, rect);
    CefBrowserHost::CreateBrowser(info, client.get(), path, b_settings, NULL);
    int result = 0;

    if ( !settings.multi_threaded_message_loop ) {
        // Run the CEF message loop. This function will block until the application
        // recieves a WM_QUIT message.
        CefRunMessageLoop();
    } else {
        // Create a hidden window for message processing.
        HWND hMessageWnd = CreateMessageWindow(hInstance);
        MSG  msg;

        // Run the application message loop.
        while ( GetMessage(&msg, NULL, 0, 0) ) {
         CefDoMessageLoopWork();
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }

        DestroyWindow(hMessageWnd);
        hMessageWnd = NULL;
        result = static_cast<int> (msg.wParam);
    }

    CefShutdown();
   tsks.StopTasks();
   Environment::ShutDown();
    return result;
}
