Focus - Notify WPF when Browser has focus #6

Open amaitland opened 4 years ago

Directly clicking the mouse in the browser and CEF will recieve focus, we need to let WPF know that our HWND host has focus in this scenario.

We need to set the Logical focus, not the actual focus. Something like the following might work.

var focusScope = FocusManager.GetFocusScope(this);
if (FocusManager.GetFocusedElement(focusScope) != this)
{
    FocusManager.SetFocusedElement(focusScope, this);
}

When the browser directly gets focus IFocusHandler.OnGotFocus should be called.
