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.

CATALOG PARTS

DRAGGER RESOURCES

.in 0n+.5i Resource: translate2Translator
.in 0n+.5i Part: translator

Appearance: pair of white crossing arrows

Description: picking this initiates translation

.in 0n+.5i Resource: translate2TranslatorActive
.in 0n+.5i Part: translatorActive

Appearance: pair of yellow crossing arrows

Description: displayed during translation instead of the translator

.in 0n+.5i Resource: translate2Feedback
.in 0n+.5i Part: feedback

Appearance: empty Separator by default

Description: feedback displayed when not moving

.in 0n+.5i Resource: translate2FeedbackActive
.in 0n+.5i 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.

.in 0n+.5i 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.
