DESCRIPTION
SoTranslate2Dragger is a simple dragger that translates in two dimensions when dragged
with the mouse. It moves within the x-y plane of its local space, determined by its
location in the scene graph. Transformation nodes placed before it will affect both the
dragger and the direction of motion.
Pressing the <Shift> key allows you to constrain motion to either the x axis or the y
axis. The direction is determined by your initial mouse gesture after pressing the key.
Releasing the key removes the constraint.
This node has a translation field which always reflects its position in local space. If
you set the field, the dragger will move 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 six parts, translator, translatorActive, feedback, feedbackActive,
xAxisFeedback, and yAxisFeedback. The last two parts are only displayed during motion, and
only when their direction of motion is enabled. (Pressing the <Shift> key and then
dragging disables one of the two directions.)
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/translate2Dragger.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 translation
Position of the dragger.
METHODS
SoTranslate2Dragger()
Constructor.
static const SoNodekitCatalog *
getClassNodekitCatalog() const
Returns an SoNodekitCatalog for this class
static SoType getClassTypeId()
Returns type identifier for this class.

Part: feedback
Appearance: empty Separator by default
Description: feedback displayed when not moving

Part: feedbackActive
Appearance: empty Separator by default
Description: feedback displayed when moving
.in 0n+.5i
Resource: translate2XAxisFeedback
.in 0n+.5i
Part: xAxisFeedback
Appearance: thin purple line
Description: Only shown if dragger is moving and the axis is a permissable direction of
motion. When pressing <shift>, motion is constrained, and this is
displayed only if the primary motion is in the x direction.

Resource: translate2YAxisFeedback
.in 0n+.5i
Part: yAxisFeedback
Appearance: thin purple line
Description: Only shown if dragger is moving and the axis is a permissable direction of
motion. When pressing <shift>, motion is constrained, and this is
displayed only if the primary motion is in the y direction.
