SoQtDevice SoQtObject List of all members.

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 }

Enumeration of spaceball input device event types.

enum SoQtSpaceball::DeviceType
 

Enumeration of spaceball input device types.


Constructor & Destructor Documentation

SoQtSpaceball::SoQtSpaceball int  mask = ALL_EVENTS  ) 
 

Public constructor. The mask argument specifies which events we are interested in.

SoQtSpaceball::~SoQtSpaceball  )  [virtual]
 

Destructor.


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.
