Using CefKeyboardHandler

[sproc]

Hello,

I have a win32 App which is using CEF for rendering Web Content. My App handles some of the Shortcut Keys (Ctrl+N, Ctrl+O, ...). But this stops happening when the CEF browser is Active or has Focus. The CEF Browser by default consumes all the Keyboard events. How to use "CefKeyboardHandler" correctly to prevent CEF Browser from handling this and pass onto my App.

If you're using 1750 branch or newer this was fixed in https://code.google.com/p/chromiumembed ... il?id=1299. You can get newer builds from http://cefbuilds.com.

I have a win32 App which is the same with sproc's, and i want to handle some custom shortcut keys. Actually, I am using the version: cef_binary_3.2217.1905_windows32.7z. the custom accelerators as shown below, but I find that can't work. Is there something wrong?
thanks for the advice.

Code: Select all

IDC_CEFCLIENT ACCELERATORS
BEGIN
    "/",            IDM_ABOUT,              ASCII,  ALT, NOINVERT
    "?",            IDM_ABOUT,              ASCII,  ALT, NOINVERT
    VK_F8,          IDM_ABOUT,                VIRTKEY, NOINVERT
END

Do they work in cefclient if the URL text field has focus instead of the browser view?

Hi magreenblatt, Thanks for your reply. But the answer is: No, they don't work whether the URL text field has focus or not. while the URL text field has focus,the keyboard events don't enter the function"bool ClientHandler::OnPreKeyEvent(...)".

The URL text field is a separate native control so it won't trigger key event callbacks. Accelerators specified in the resource file will not work in combination with CefRunMessageLoop. You likely need to implement your own accelerator logic in OnPreKeyEvent.

try cefsettings.multi_threaded_message_loop = true,maybe it works.
