DESCRIPTION

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

METHODS

42                         SoXtInputFocus(EventMask            mask            =
43                              SO_XT_ALL_FOCUS_EVENTS)
44                         ~SoXtInputFocus()
45          Constructor and destructor. To the  constructor,  pass  which  input
46          focus  events you are interested in as a bitwise OR of the following
47          values:
48
49          EnterWindowMask — Input focus entered the window
50
51          LeaveWindowMask — Input focus left the window
52
53          Or simply pass the  defined  value  SO_XT_ALL_FOCUS_EVENTS  for  all
54          input focus events.
