   2
   3 A focus event is sent when a window's focus changes. The window losing focus
   4 receives a ``kill focus'' event while the window gaining it gets a ``set
   5 focus'' one.
   6
   7 Notice that the set focus event happens both when the user gives focus to the
   8 window (whether using the mouse or keyboard) and when it is done from the
   9 program itself using \helpref{SetFocus}{wxwindowsetfocus}.

  27 function that takes a wxFocusEvent argument.

  51 Returns the window associated with this event, that is the window which had the
  52 focus before for the \texttt{wxEVT\_SET\_FOCUS} event and the window which is
  53 going to receive focus for the \texttt{wxEVT\_KILL\_FOCUS} one.

  55 Warning: the window pointer may be \texttt{NULL}!
