How to check if the browser has focus ?

[silver]

Hi

SendFocusEvent/SetFocus can be used to put the browser "control" under focus.
Is there a function that can tell if it has focus or not ?

You can implement `CefFocusHandler` from which you can track the focus. Make sure to read the method descriptions in detail.

The OnGotFocus method seems to be called when SetFocus is invoked on the browser.

However the OnTakeFocus method of CefFocusHandler is not being called when the focus is moved away from the browser component,
so its not possible to track if the browser does not have focus.

Tried on Windows 7 64bit

If you require more than being notified when the user tabs out of the browser then you'll have to look at a lower level approach.

The following should work even though it's asking in relation to `CEF1`

I am using multi_threaded_message_loop = true ,
I guess my application's main event loop will not receive WM_SETFOCUS/WM_KILLFOCUS that happen on the browser control

The WinAPI GetFocus function will tell you what window has focus. You can then walk the window hierarchy using GetAncestor to determine if it's the browser window or some other application window.

Would it be feasible to expand `OnTakeFocus` to provide notification for more than just tabbing out of the browser?

Thanks. The Winapi GetFocus function seems to work.
