129 SoScale2Dragger is a simple dragger that scales freely and indepen‐
130 dently in two dimensions when dragged with the mouse. It moves within
131 the x-y plane of its local space, as determined by its location in the
132 scene graph. Transformation nodes placed before it will affect both
133 the dragger and the plane of motion.
134 This node has a scaleFactor field which always reflects its size in
136 local space. If you set the field, the dragger will change accordingly.
137 You can also connect fields of other nodes or engines from this one to
138 make them follow the dragger's motion.
139 This dragger contains four parts, scaler, scalerActive, feedback, and
141 feedbackActive.
142 Each of these is set by default from a resource described in the Drag‐
144 ger Resources section of the online reference page for this class. You
145 can change the parts in any instance of this dragger using setPart().
146 You can make your program use different default resources for the parts
148 by copying the file /usr/share/data/draggerDefaults/scale2Dragger.iv
149 into your own directory, editing the file, and then setting the envi‐
150 ronment variable SO_DRAGGER_DIR to be a path to that directory.
