Additional Inherited Members

The SoTranslate2Dragger class provides a mechanism for the end-user to translate in a plane.

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.)

By holding down a SHIFT key, the end-user can temporarily constrain the dragger to a single one of the two axes.

SoTranslate2Dragger::SoTranslate2Dragger (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):

      "callbackList"
      "topSeparator"
         "motionMatrix"
         "geomSeparator"

SoTranslate2Dragger::~SoTranslate2Dragger (void)\fC [protected]\fP, \fC [virtual]\fP

Protected destructor.

(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)

\fBSoType\fP SoTranslate2Dragger::getTypeId (void) const\fC [virtual]\fP

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.

const \fBSoFieldData\fP * SoTranslate2Dragger::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP

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 \fBSoNodekitCatalog\fP * SoTranslate2Dragger::getNodekitCatalog (void) const\fC [virtual]\fP

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoDragger.

SbBool SoTranslate2Dragger::setUpConnections (SbBoolonoff, SbBooldoitalways = \fCFALSE\fP)\fC [protected]\fP, \fC [virtual]\fP

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 SoTranslate2Dragger::setMotionMatrix (const \fBSbMatrix\fP &matrix)\fC [protected]\fP, \fC [virtual]\fP

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 SoTranslate2Dragger::startCB (void *f, \fBSoDragger\fP *d)\fC [static]\fP, \fC [protected]\fP

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

void SoTranslate2Dragger::motionCB (void *f, \fBSoDragger\fP *d)\fC [static]\fP, \fC [protected]\fP

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

void SoTranslate2Dragger::finishCB (void *f, \fBSoDragger\fP *d)\fC [static]\fP, \fC [protected]\fP

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

void SoTranslate2Dragger::valueChangedCB (void *f, \fBSoDragger\fP *d)\fC [static]\fP, \fC [protected]\fP

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

void SoTranslate2Dragger::dragStart (void)\fC [protected]\fP

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 SoTranslate2Dragger::drag (void)\fC [protected]\fP

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 SoTranslate2Dragger::dragFinish (void)\fC [protected]\fP

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.

\fBSoSFVec3f\fP SoTranslate2Dragger::translation

Continuously updated to contain the current translation from the dragger's local origo position. Only the first two components (the X and Y values) 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.

\fBSoFieldSensor\fP * SoTranslate2Dragger::fieldSensor\fC [protected]\fP
