DESCRIPTION¶
SoHandleBoxDragger is a dragger shaped like a wireframe box with small corner cubes mounted on each corner. Click and drag any of these cubes to scale the box uniformly. Six other center cubes are centered on the sides of the box; white lines connect them to the center of the dragger. Drag one of the center cubes along its line to stretch the box in that direction. Dragging a face of the box translates the dragger within that plane.
While you drag a face of the box, purple feedback arrows display the possible directions of motion. Press the <Shift> key to constrain the motion to one of the two major directions in the plane. The constraint direction is chosen based on the next user gesture. Press the <Control> key and the dragger will translate perpendicular to that plane. The translation field is modified as the face is dragged.
By default, dragging any of the small cubes scales about the center of the object. Pressing the <Control> key changes this: A corner cube will scale about its opposite corner. A center cube will scale about the center of its opposite face. Dragging one of the small cubes will usually result in changes to both the scaleFactor and translation fields. This is because any scale about a point other than the origin has a translation element.
As with all draggers, if you change the fields the dragger will move to match the new settings.
Remember: This is not an SoTransform!. If you want to move other objects with this dragger, you can either:
[a] Use an SoHandleBoxManip, which is subclassed from SoTransform. It creates one of these draggers and uses it as the interface to change its fields. (see the SoHandleBoxManip reference page).
[b] Use field-to-field connections to connect the fields of this dragger to those of any SoTransformation node.
You can change the parts in any instance of this dragger using setPart(). The default part geometries are defined as resources for this SoHandleBoxDragger class. They are detailed in the Dragger Resources section of the online reference page for this class. You can make your program use different default resources for the parts by copying the file /usr/share/data/draggerDefaults/handleBoxDragger.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

NOTE¶
Unlike most multi-function draggers, SoHandleBoxDragger is not a compound dragger made up of other draggers that perform its smaller tasks. This is not because it was inappropriate, but because was written before implementation of the methods that synchronize multiple child draggers. The younger SoTransformBoxDragger has similarities to the handle box dragger, but the transform box dragger is a compound dragger.
