HWND_TOPMOST

[ScottV]

On Windows is there a way to get the HWND of the process that is rendering the HTML in order to move it to the top of the z-order?

In the Windows cef_client application when setting the window as the top most window the HTML select boxes do not show.

Code: Select all

   
case WM_CREATE: {
      // Create the single static handler class instance
      g_handler = new ClientHandler();
      g_handler->SetMainHwnd(hWnd);

      // set as top most
      SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW);


I have tried using the "browser->GetHost()->GetWindowHandle()" in the client_handler but this does not make a difference.

Code: Select all

void ClientHandler::OnAfterCreated(CefRefPtr<CefBrowser> browser) {
  REQUIRE_UI_THREAD();

  // set as top most
  HWND hWnd = browser->GetHost()->GetWindowHandle();
  SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW);

This has been tested on Windows with the following CEF3 versions:
Windows 32bit 2014-07-18 CEF 3.2078.1780
Windows 32bit 2014-07-18 CEF 3.1916.1781
Windows 32bit 2014-07-18 CEF 3.1750.1738

Looks like a Chromium bug. See https://code.google.com/p/chromiumembed ... ail?id=972.

Hi

Has this issue been fixed either in chromium or CEF? I'm having an issue with the dropdowns not working when using TopMost in my container. I'm using CEF 3.2623.1401 (Chromium 49.0.2623.110)

Thanks
