DESCRIPTIONSoScale2Dragger is a simple dragger that scales freely and independently
in two dimensions when dragged with the mouse. It moves within the x-y
plane of its local space, as determined by its location in the scene
graph. Transformation nodes placed before it will affect both the
dragger and the plane of motion.
This node has a scaleFactor field which always reflects its size in local
space. If you set the field, the dragger will change accordingly. You can
also connect fields of other nodes or engines from this one to make them
follow the dragger's motion.
This dragger contains four parts, scaler, scalerActive, feedback, and
feedbackActive.
Each of these is set by default from a resource described in the Dragger
Resources section of the online reference page for this class. You can
change the parts in any instance of this dragger using
SoDraggerSetPart().
Page 3SoScale2Dragger(3IV)
You can make your program use different default resources for the parts
by copying the file /usr/share/data/draggerDefaults/scale2Dragger.iv into
your own directory, editing the file, and then setting the environment
variable SO_DRAGGER_DIR to be a path to that directory.
FIELDS
SoSFVec3f scaleFactor
Scale factor affecting the dragger.
FUNCTIONSSoScale2Dragger * SoScale2DragCreate()
Constructor.
const SoNodekitCatalog * SoScale2DragGetClassNkitCat()
Returns an SoNodekitCatalog for this class
SoType SoScale2DragGetClassTypeId()
Returns type identifier for this class.
