SoXtDevice(3IV)

NAME
     SoXtDevice (SoXtDev) - abstract base class device for use with the
     SoXtRenderArea

INHERITS FROM
     SoXtDevice

SYNOPSIS
     #include <Inventor_c/Xt/devices/SoXtDevice.h>

     typedef SoXtDevice  SoXtDev

          Functions from class SoXtDevice:

     void                SoXtDevEnable(SoXtDev *this, Widget w, XtEventHandler
                              f, XtPointer data, Window win = NULL)
     void                SoXtDevDisable(SoXtDev *this, Widget w,
                              XtEventHandler f, XtPointer data)
     const SoEvent *     SoXtDevXlateEv(SoXtDev *this, XAnyEvent *xevent)
     void                SoXtDevSetWinSize(SoXtDev *this, const SbVec2s *size)
     const SbVec2s *     SoXtDevGetWinSize(const SoXtDev *this)


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.

FUNCTIONS
     void                SoXtDevEnable(SoXtDev *this, Widget w, XtEventHandler
                              f, XtPointer data, Window win = NULL)
     void                SoXtDevDisable(SoXtDev *this, 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.

     const SoEvent *     SoXtDevXlateEv(SoXtDev *this, 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                SoXtDevSetWinSize(SoXtDev *this, const SbVec2s *size)
     const SbVec2s *     SoXtDevGetWinSize(const SoXtDev *this)
          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.)
