Detailed Description

Translates and reports events for a SpaceBall or SpaceMouse (Magellan) device.

This class manages events generated by the spaceball, including spaceball motion (SoMotion3Event), and spaceball button press and release events (SoSpaceballButtonEvent).

Member Function Documentation

virtual void SoXtSpaceball::disable ( SoWidget  w,
XtEventHandler  f,
XtPointer  data 
) [virtual]

Disables this device for the passed widget.

The callback function f will be invoked when events occur in w. Data is the clientData which will be passed.

Implements SoXtDevice.

virtual void SoXtSpaceball::enable ( SoWidget  w,
XtEventHandler  f,
XtPointer  data,
Window  win = 0 
) [virtual]

Enables this device for the passed widget.

The callback function f will be invoked when events occur in w. Data is the clientData which will be passed.

Implements SoXtDevice.

static SbBool SoXtSpaceball::exists ( Display *  d  )  [static]

Returns whether or not the spaceball device exists for use.

static SbBool SoXtSpaceball::exists (  )  [inline, static]

Returns whether or not the spaceball device exists for use.

float SoXtSpaceball::getRotationScaleFactor (  )  const [inline]

Returns the rotation scale factor.

float SoXtSpaceball::getTranslationScaleFactor (  )  const [inline]

Returns the translation scale factor.

SbBool SoXtSpaceball::isFocusToWindow (  )  const [inline]

Gets the input focus method.

See setFocusToWindow() for details.

void SoXtSpaceball::setFocusToWindow ( SbBool  flag  ) 

Sets the input focus method used to get events from the space ball.

If FALSE: SpaceBall events are received only if the cursor is in the window or when the window has the focus (default).
If TRUE: SpaceBall events are received even if cursor is out of the window.

void SoXtSpaceball::setRotationScaleFactor ( float  f  )  [inline]

The spaceball reports rotations and translations as integers.

These values must be scaled to be useful. This method sets the rotation scale factor. Default is .006.

void SoXtSpaceball::setTranslationScaleFactor ( float  f  )  [inline]

The spaceball reports rotations and translations as integers.

These values must be scaled to be useful. This method sets the translation scale factor. Default is .006.

virtual const SoEvent* SoXtSpaceball::translateEvent ( XAnyEvent *  xevent  )  [virtual]

This converts a system event into an SoEvent, returning NULL if the event is not from this device.

Implements SoXtDevice.
