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 SoQtSpaceball::disable | ( | QWidget * | w, | |
| XtEventHandler | f, | |||
| XtPointer | data | |||
| ) | [virtual] |
Disables the device for the passed widget.
Implements SoQtDevice.
| virtual void SoQtSpaceball::enable | ( | QWidget * | w, | |
| XtEventHandler | f, | |||
| XtPointer | data, | |||
| void * | unused = NULL | |||
| ) | [virtual] |
Enables the device for the passed widget. When enabled, the callback function f will be invoked when events occur in the window. data is the clientData which will be passed.
Implements SoQtDevice.
| static SbBool SoQtSpaceball::exists | ( | SbGlContextHelper::Display | d | ) | [static] |
Returns whether or not the spaceball device exists for use.
| static SbBool SoQtSpaceball::exists | ( | ) | [inline, static] |
Returns whether or not the spaceball device exists for use.
| float SoQtSpaceball::getRotationScaleFactor | ( | ) | const [inline] |
Returns the rotation scale factor.
| float SoQtSpaceball::getTranslationScaleFactor | ( | ) | const [inline] |
Returns the translation scale factor.
| SbBool SoQtSpaceball::isFocusToWindow | ( | ) | const [inline] |
Gets the input focus method.
See setFocusToWindow() for details.
| void SoQtSpaceball::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 SoQtSpaceball::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 SoQtSpaceball::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* SoQtSpaceball::translateEvent | ( | QEvent * | xevent | ) | [virtual] |
Attempts to convert the passed event into an SoEvent.
Returns a pointer to an internal SoEvent object owned by the class. Do not delete this object. If the message was not generated by this device, then NULL is returned.
Implements SoQtDevice.
