Detailed Description

The SoQtSpaceball class is the spaceball input device abstraction.

The SoQtSpaceball class is the glue between native spaceball handling and how those events translates to generic events for the Inventor API scenegraph.

Public Types
enum	Mask {   MOTION_EVENT = 0x01, MOTION = MOTION_EVENT, PRESS_EVENT = 0x02, PRESS = PRESS_EVENT,   RELEASE_EVENT = 0x04, RELEASE = RELEASE_EVENT, ALL_EVENTS = MOTION_EVENT | PRESS_EVENT | RELEASE_EVENT, ALL = ALL_EVENTS }
enum	DeviceType { SPACE_BALL = 0x01, MAGELLAN_SPACE_MOUSE = 0x02 }

Member Function Documentation

void SoQtSpaceball::enable (  QWidget *  widget, SoQtEventHandler *  handler, void *  closure )  [virtual]

This method will enable the device for the widget. handler is invoked with the closure argument when an event occur in widget. Implements SoQtDevice.

void SoQtSpaceball::disable (  QWidget *  widget, SoQtEventHandler *  handler, void *  closure )  [virtual]

This method will disable the handler for the device. Implements SoQtDevice.

const SoEvent * SoQtSpaceball::translateEvent (  QEvent *  event  )  [virtual]

This method translates from native events to Open Inventor SoEvent events. Implements SoQtDevice.

void SoQtSpaceball::setRotationScaleFactor (  float  f  )

This method sets the scale factor for the spaceball rotation vectors.

float SoQtSpaceball::getRotationScaleFactor (  void   )  const

This method returns the scale factor for the spaceball rotation vectors.

void SoQtSpaceball::setTranslationScaleFactor (  float  f  )

This method sets the scale factor for the spaceball translation vectors.

float SoQtSpaceball::getTranslationScaleFactor (  void   )  const

This method returns the scale factor for the spaceball translation vectors.

SbBool SoQtSpaceball::exists (  void   )  [static]

Returns TRUE iff there could be a device of this type available on the system. Note that a return value of TRUE does not signify that there is such a device active.

void SoQtSpaceball::setFocusToWindow (  SbBool  flag  )

Set to TRUE if you want spaceball events to be received even when the component does not have focus.

SbBool SoQtSpaceball::isFocusToWindow (  void   )  const

Returns whether or not spaceball events are caught even when the component does not have focus.
