## DESCRIPTION

**SoJackDragger** is a composite dragger in the shape of a jack from the children's game jacks. Three lines along the x, y, and z axes form the central star shape, which you can drag with the mouse to rotate the jack. Dragging any of the small cubes mounted at the end of the axes will scale the jack uniformly in all 3 dimensions. At the core of the jack is an **SoDragPointDragger** for translating the jack.

Each of these shapes is a different dragger with the default geometry changed. All of them are parts of the jack dragger, which keeps them moving together. The star is an **SoRotateSphericalDragger**, and dragging it updates the **rotation** field of the jack dragger. The small cubes are an **SoScaleUniformDragger**, tied to the **scaleFactor** field. The position of the **SoDragPointDragger** is given by the **translation** field. 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 **SoJackManip**, which is subclassed from **SoTransform**. It creates one of these draggers and uses it as the interface to change its fields. (see the **SoJackManip** man 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 **SoJackDragger** 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/jackDragger.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

**SoSFRotation**	**rotation**\
 Orientation of the dragger.

**SoSFVec3f**	**scaleFactor**\
 Scale of the dragger.

**SoSFVec3f**	**translation**\
 Position of the dragger.

## METHODS

	**SoJackDragger()**\
 Constructor.

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

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