public virtual void OnFocusedNodeChanged( CefRefPtr< CefBrowser > browser, CefRefPtr< CefFrame > frame, CefRefPtr< CefDOMNode > node );

Called when a new node in the the browser gets focus. The |node| value may be empty if no specific node has gained focus. The node object passed to this method represents a snapshot of the DOM at the time this method is executed. DOM objects are only valid for the scope of this method. Do not keep references to or attempt to access any DOM objects outside the scope of this method.

OnSetFocus

public virtual bool OnSetFocus( CefRefPtr< CefBrowser > browser, CefFocusHandler::FocusSource source );

Called when the browser component is requesting focus. |source| indicates where the focus request is originating from. Return false to allow the focus to be set or true to cancel setting the focus.

OnTakeFocus

public virtual void OnTakeFocus( CefRefPtr< CefBrowser > browser, bool next );

Called when the browser component is about to loose focus. For instance, if focus was on the last HTML element and the user pressed the TAB key. |next| will be true if the browser is giving focus to the next component and false if the browser is giving focus to the previous component.
