Keydown in MFC

[tom]

Hello and wonder if you can help

I am trying to add a WM_KEYDOWN to my CEF class. This is so I can make F5 refresh of the page. The problem is that the Chromium doesn't pass the event WM_KEYDOWN back. So what event would key down be?

Hi Tom,

I haven't tried this, but from reading the Chromium sources I believe you will need to do something like the following:

1. Modify webwidget_host.cc WebWidgetHost::WndProc to store the key press from key-related Windows messages. This is basically what Chromium does in browser/renderer_host/render_widget_host_view_win.cc RenderWidgetHostViewWin::OnKeyEvent().

2. Implement the handleCurrentKeyboardEvent() method from WebKit::WebViewClient in browser_webview_delegate to be notified if WebKit did not handle the key press.

Regards,
Marshall

An alternative approach might be intercepting the keyboard events by overriding OnWndMsg() or PreTranslateMessage() in the MFC window class that is the parent of the CEF browser window. I'm not sure whether that will work in your particular case though.

I have implemented the first option, which seems to work. I have a patch here as the changes may be useful; there does not seem to be an open issue for this, so should one be created to attach it to?

Thanks.

Cool, I'm glad to hear it worked for you. Please create an issue and attach your patch.

Thanks,
