Additional Inherited Members

The SoScaleUniformDragger class provides a mechanism for the end-user to scale in three dimensions.

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 scale simultaneously along all the axes.

Scaling with this dragger can only be done in a uniform manner, ie the X, Y and Z components of the SoScaleUniformDragger::scaleFactor will always be exactly equal.

SoScaleUniformDragger::SoScaleUniformDragger (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 SoScaleUniformDragger
-->"this"
      "callbackList"
      "topSeparator"
         "motionMatrix"
         "geomSeparator"
-->         "scalerSwitch"
-->            "scaler"
-->            "scalerActive"
-->         "feedbackSwitch"
-->            "feedback"
-->            "feedbackActive"

(See SoBaseKit::printDiagram() for information about the output formatting.)

Detailed information on catalog parts:

CLASS SoScaleUniformDragger
PVT   "this",  SoScaleUniformDragger  ---
      "callbackList",  SoNodeKitListPart [ SoCallback, SoEventCallback ]
PVT   "topSeparator",  SoSeparator  ---
PVT   "motionMatrix",  SoMatrixTransform  ---
PVT   "geomSeparator",  SoSeparator  ---

SoScaleUniformDragger::~SoScaleUniformDragger (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 SoScaleUniformDragger::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 * SoScaleUniformDragger::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 * SoScaleUniformDragger::getNodekitCatalog (void) const\fC [virtual]\fP

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

Reimplemented from SoDragger.

SbBool SoScaleUniformDragger::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.)
