DESCRIPTION
SoScale2UniformDragger is a simple dragger that scales uniformly in the x and y dimensions when dragged within the x-y plane with the mouse. The local space is 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 Resource section of the online reference page for this class. You can change the parts in any instance of this dragger using setPart().

You can make your program use different default resources for the parts by copying the file /usr/share/data/draggerDefaults/scale2UniformDragger.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.

METHODS

SoScale2UniformDragger()
Constructor.

static const SoNodekitCatalog *
getClassNodekitCatalog() const
Returns an SoNodekitCatalog for this class

static SoType
getClassTypeId()
Returns type identifier for this class.
