Detailed Description
The SoTranslate1Dragger class provides a mechanism for the end-user to translate along an axis.
Here's how the dragger looks with its default geometry in the inactive state:.
Use this dragger to allow the end-user of your application to translate along the X-axis and the Y-axis at the same time, ie freely inside a 3D plane. (Use a transformation node in front of the dragger to position it and re-orient it to translate in any plane.)

Constructor & Destructor Documentation
SoTranslate1Dragger::SoTranslate1Dragger (void)Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.
Node kit structure (new entries versus parent class marked with arrow prefix):
CLASS SoTranslate1Dragger -->"this" "callbackList" "topSeparator" "motionMatrix" "geomSeparator" --> "translatorSwitch" --> "translator" --> "translatorActive" --> "feedbackSwitch" --> "feedback" --> "feedbackActive" .fi (See SoBaseKit::printDiagram() for information about the output formatting.) Detailed information on catalog parts: CLASS SoTranslate1Dragger PVT "this", SoTranslate1Dragger --- "callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ] PVT "topSeparator", SoSeparator --- PVT "motionMatrix", SoMatrixTransform --- PVT "geomSeparator", SoSeparator --- PVT "translatorSwitch", SoSwitch --- "translator", SoSeparator --- "translatorActive", SoSeparator --- PVT "feedbackSwitch", SoSwitch --- "feedback", SoSeparator --- "feedbackActive", SoSeparator --- .fi (See SoBaseKit::printTable() for information about the output formatting.)

SoTranslate1Dragger::~SoTranslate1Dragger () [protected]Protected destructor.
(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)

Member Function Documentation
void SoTranslate1Dragger::initClass (void) [static]Initializes type system for this dragger class.
Application programmers should usually not have to invoke this method, see documentation of SoInteraction::init().
Reimplemented from SoDragger.
SbBool SoTranslate1Dragger::setUpConnections (SbBool onoff, SbBool doitalways = 0) [protected, virtual]Sets up all internal connections for instances of this class.
(This method will usually not be of interest to the application programmer, unless you want to extend the library with new custom nodekits or dragger classes. If so, see the SoBaseKit class documentation.)
Reimplemented from SoInteractionKit.

Member Data Documentation
SoSFVec3f SoTranslate1Dragger::translationContinuously updated to contain the current translation from the dragger's local origo position. Only the first component (the X value) can be changed by the end-user.
The application programmer applying this dragger in his code should connect the relevant node fields in the scene to this field to make it follow the dragger.
