DESCRIPTION

SoScale2Dragger 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 setPart().

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.

METHODS

SoScale2Dragger()

Constructor.

static const SoNodekitCatalog * getClassNodekitCatalog() const

Returns an SoNodekitCatalog for this class

static SoType getClassTypeId()

Returns type identifier for this class.
