NAME

       SoXtInputFocus -- reports input focus change events

INHERITS FROM

       SoXtDevice > SoXtInputFocus

SYNOPSIS

       #include <Inventor/Xt/devices/SoXtInputFocus.h>

       #define SO_XT_ALL_FOCUS_EVENTS (EnterWindowMask | LeaveWindowMask)

	  Methods from class SoXtInputFocus:

			 SoXtInputFocus(EventMask mask = SO_XT_ALL_FOCUS_EVENTS)
			 ~SoXtInputFocus()

	  Methods from class SoXtDevice:

     virtual void	      enable(Widget w, XtEventHandler f, XtPointer data, Window win = NULL)
     virtual void	      disable(Widget w, XtEventHandler f, XtPointer data)
     virtual const SoEvent *  translateEvent(XAnyEvent *xevent)
     void		      setWindowSize(const SbVec2s &size)
     const SbVec2s &	      getWindowSize() const

DESCRIPTION

       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.)

METHODS

			 SoXtInputFocus(EventMask mask = SO_XT_ALL_FOCUS_EVENTS)
			 ~SoXtInputFocus()
	  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.

NAME

       SoXtDevice -- abstract base class device for use with the SoXtRenderArea

INHERITS FROM

       SoXtDevice

SYNOPSIS

       #include <Inventor/Xt/devices/SoXtDevice.h>

	  Methods from class SoXtDevice:

     virtual void	      enable(Widget w, XtEventHandler f, XtPointer data, Window win = NULL)
     virtual void	      disable(Widget w, XtEventHandler f, XtPointer data)
     virtual const SoEvent *  translateEvent(XAnyEvent *xevent)
     void		      setWindowSize(const SbVec2s &size)
     const SbVec2s &	      getWindowSize() const

DESCRIPTION

       This  is the abstract base class for devices in the Inventor Xt component and utility library. When a device is registered with an SoXtRen-
       derArea, the device is able to generate events in the render area window.

METHODS

     virtual void	      enable(Widget w, XtEventHandler f, XtPointer data, Window win = NULL)
     virtual void	      disable(Widget w, XtEventHandler f, XtPointer data)
	  Enable and disable the device for the passed widget. When enabled, the callback function f will be invoked when events occur in the wid-
	  get. data is the clientData which will be passed.

     virtual const SoEvent *  translateEvent(XAnyEvent *xevent)
	  This attempts to convert the passed X event into an SoEvent. If the event was not generated by this device, then NULL is returned.

     void		      setWindowSize(const SbVec2s &size)
     const SbVec2s &	      getWindowSize() const
	  Set  and  get the window size of the widget this device is registered for. This allows the device to correctly convert position informa-
	  tion from X window coordinates (origin at top left) to Inventor window coordinates (origin at bottom left). (SoXtRenderArea  will  auto-
	  matically call this method for each device registered on it whenever the window size changes.)
