Detailed Description

SoScaleUniformDragger is a simple dragger that scales uniformly in all 3 dimensions when dragged 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 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/scaleUniformDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

Called by: start/end of SoBaseKit::readInstance and on new copy by: start/end of SoBaseKit::copy. Classes that redefine must call setUpConnections(TRUE,TRUE) at end of constructor. Returns the state of the node when this was called.

Member Data Documentation

SoFieldSensor* SoScaleUniformDragger::fieldSensor [protected]

If the part changes to a new node, then the fields of the old part will be disconnected and the fields of the new part will be connected. Connections are made from/to the renderCaching, boundingBoxCaching, renderCulling and pickCulling fields. This way, the SoInteractionKit can be treated from the outside just like a regular SoSeparator node. Setting the fields will affect caching and culling, even though the topSeparator takes care of it. oldTopSep keeps track of the part for comparison.
