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

disable()

virtual void SoQtSpaceball::disable ( QWidget *  w, XtEventHandler  f, XtPointer  data  )

virtual

Disables the device for the passed widget.

Implements SoQtDevice.

enable()

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.

exists() [1/2]

static SbBool SoQtSpaceball::exists ( )

inlinestatic

Returns whether or not the spaceball device exists for use.

Definition at line 133 of file SoQtSpaceball.h.

exists() [2/2]

static SbBool SoQtSpaceball::exists ( SbGlContextHelper::Display  d )

static

Returns whether or not the spaceball device exists for use.

getRotationScaleFactor()

float SoQtSpaceball::getRotationScaleFactor ( ) const

inline

Returns the rotation scale factor.

Definition at line 118 of file SoQtSpaceball.h.

getTranslationScaleFactor()

float SoQtSpaceball::getTranslationScaleFactor ( ) const

inline

Returns the translation scale factor.

Definition at line 128 of file SoQtSpaceball.h.

isFocusToWindow()

SbBool SoQtSpaceball::isFocusToWindow ( ) const

inline

Gets the input focus method.

See setFocusToWindow() for details.

Definition at line 149 of file SoQtSpaceball.h.

setFocusToWindow()

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.

setRotationScaleFactor()

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.

Definition at line 114 of file SoQtSpaceball.h.

setTranslationScaleFactor()

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.

Definition at line 124 of file SoQtSpaceball.h.

translateEvent()

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.
