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 SoXtRenderArea, 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 widget. 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 information from X window coordinates (origin  at  top  left)  to  Inventor
          window  coordinates  (origin  at bottom left). (SoXtRenderArea will automatically call this method for
          each device registered on it whenever the window size changes.)
