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,
ie freely along a line. (Use a transformation node in front of the dragger to position it
and re-orient it to translate along any line.)

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"
(See SoBaseKit::printDiagram() for information about the output formatting.)
Detailed information on catalog parts:

SoTranslate1Dragger::~SoTranslate1Dragger (void) [protected], [virtual]
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
SoType SoTranslate1Dragger::getTypeId (void) const [virtual]
Returns the type identification of an object derived from a class inheriting SoBase. This
is used for run-time type checking and 'downward' casting. Usage example:
void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}
For application programmers wanting to extend the library with new nodes, engines,
nodekits, draggers or others: this method needs to be overridden in all subclasses. This
is typically done as part of setting up the full type system for extension classes, which
is usually accomplished by using the pre-defined macros available through for instance
Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes),
Inventor/engines/SoSubEngine.h (for engine classes) and so on.
For more information on writing Coin extensions, see the class documentation of the
toplevel superclasses for the various class groups.
Reimplemented from SoDragger.
const SoFieldData * SoTranslate1Dragger::getFieldData (void) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no
fields are present, returns NULL.
Reimplemented from SoDragger.
const SoNodekitCatalog * SoTranslate1Dragger::getNodekitCatalog (void) const [virtual]
Returns the nodekit catalog which defines the layout of this class' kit.
Reimplemented from SoDragger.
SbBool SoTranslate1Dragger::setUpConnections (SbBoolonoff, SbBooldoitalways = FALSE)
[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.
void SoTranslate1Dragger::setMotionMatrix (const SbMatrix &matrix) [protected], [virtual]
Sets a new current motion matrix for the dragger geometry.
Triggers value changed callbacks if matrix is unequal to the previous motion matrix.
Reimplemented from SoDragger.
void SoTranslate1Dragger::startCB (void *f, SoDragger *d) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer.
void SoTranslate1Dragger::motionCB (void *f, SoDragger *d) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer.
void SoTranslate1Dragger::finishCB (void *f, SoDragger *d) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer.
void SoTranslate1Dragger::fieldSensorCB (void *d, SoSensor *s) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer.
void SoTranslate1Dragger::valueChangedCB (void *f, SoDragger *d) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer.
void SoTranslate1Dragger::dragStart (void) [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer. Called when dragger is selected (picked) by the
user.
void SoTranslate1Dragger::drag (void) [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer. Called when user drags the mouse after picking the
dragger.
void SoTranslate1Dragger::dragFinish (void) [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer. Called when mouse button is released after picking
and interacting with the dragger.
Member Data Documentation
SoSFVec3f SoTranslate1Dragger::translation
Continuously 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.
SoSFVec2f SoTranslate1Dragger::minTranslation
Sets the minimum value allowed in the x component of the translaton field. This is only
active if minTranslation <= maxTranslation.
Default value is 1.0
Since:
Coin 3.0
Sets the minimum value allowed in each component of the translaton field. This is only
active if minTranslation <= maxTranslation for each component.
Default value is [1.0, 1.0]
Since:
Coin 3.0
SoSFVec2f SoTranslate1Dragger::maxTranslation
Sets the maximum value allowed in the x component of the translaton field. This is only
active if minTranslation <= maxTranslation.
Default value is 0.0.
Since:
Coin 3.0
Sets the maximum value allowed in each component of the translaton field. This is only
active if minTranslation <= maxTranslation for each component.
Default value is [0.0, 0.0]
Since:
Coin 3.0
SoFieldSensor * SoTranslate1Dragger::fieldSensor [protected]
This API member is considered internal to the library, as it is not likely to be of
interest to the application programmer.
SbLineProjector * SoTranslate1Dragger::lineProj [protected]
The SbLineProjector instance used for projecting from 2D mouse cursor positions to 3D
points.
