SoXtInputFocus — reports input focus change events

       This  class  reports  input focus change events (i.e. when the cursor crosses into or out of the window).
       There are no input focus events in Inventor, so this always returns NULL when asked to translate  events.
       When this class is registered on a render area, the render area will receive X input focus change events.
       (This class is extensively employed by the viewer classes.)

          Constructor and destructor. To the constructor, pass which input focus events you are interested in as
          a bitwise OR of the following values:

          EnterWindowMask — Input focus entered the window

          LeaveWindowMask — Input focus left the window

          Or simply pass the defined value SO_XT_ALL_FOCUS_EVENTS for all input focus events.
