NAME

SoInteractionKit -

The SoInteractionKit class is a base class for draggers.

This nodekit class makes it possible to set surrogate paths for parts. Instead of creating new geometry for the dragger, it is possible to specify an existing path in your scene to be used for interaction. All picks on this path will be handled by the dragger.

Detailed Description

The SoInteractionKit class is a base class for draggers.

This nodekit class makes it possible to set surrogate paths for parts. Instead of creating new geometry for the dragger, it is possible to specify an existing path in your scene to be used for interaction. All picks on this path will be handled by the dragger.

The SoInteractionKit is primarily an internal class used as a superclass for the dragger classes, and it is unlikely that it should be of interest to application programmers, unless you have very special needs in your application.

Node kit structure (new entries versus parent class marked with arrow prefix):

 
   CLASS SoInteractionKit
   -->"this"
         "callbackList"
   -->   "topSeparator"
   -->      "geomSeparator"
   .fi
 
 
 (See SoBaseKit::printDiagram() for information about the output formatting.)
 
 Detailed information on catalog parts:
 
 
 
   CLASS SoInteractionKit

Member Enumeration Documentation

enum SoInteractionKit::CacheEnabledEnumeration of valid values for the cache control fields SoInteractionKit::renderCaching, SoInteractionKit::boundingBoxCaching, SoInteractionKit::renderCulling and SoInteractionKit::pickCulling.

The same values with the same semantics are present in this enum as for SoSeparator::CacheEnabled, so see that documentation.

Member Function Documentation

void SoInteractionKit::initClass (void) [static]Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoBaseKit.

Reimplemented in SoCenterballDragger, SoDirectionalLightDragger, SoDragPointDragger, SoDragger, SoHandleBoxDragger, SoJackDragger, SoPointLightDragger, SoRotateCylindricalDragger, SoRotateDiscDragger, SoRotateSphericalDragger, SoScale1Dragger, SoScale2Dragger, SoScale2UniformDragger, SoScaleUniformDragger, SoSpotLightDragger, SoTabBoxDragger, SoTabPlaneDragger, SoTrackballDragger, SoTransformBoxDragger, SoTransformerDragger, SoTranslate1Dragger, and SoTranslate2Dragger.

SbBool SoInteractionKit::setPartAsPath (const SbName & partname, SoPath * path) [virtual]Sets a part in the kit as a surrogate path. The partname part is set to NULL, and the surrogate path is remembered. Following picks on the surrogate path will be regarded as a pick on partname.

References setAnySurrogatePath().

SbBool SoInteractionKit::setPartAsDefault (const SbName & partname, SoNode * node, SbBool onlyifdefault = 1) [virtual]Sets the value of partname to node, and sets the part's field to default (i.e. node will not be written on scene graph export).

If onlyifdefault is TRUE, partname is only set if it is already in the default state.

The reason for this method is to make it possible for dragger subclasses to avoid having their default parts written out on export.

SbBool SoInteractionKit::isPathSurrogateInMySubgraph (const SoPath * path, SoPath *& pathToOwner, SbName & surrogatename, SoPath *& surrogatepath, SbBool fillargs = 1)Checks if path is contained within any of the surrogate paths in any interaction kits from this node down. Returns information about the owner and the surrogate path if found, and fillargs is TRUE. The returned path (pathToOwner) is not ref'ed, It's the callers responsibility to ref and unref this path.

SbBool SoInteractionKit::setPart (const SbName & partname, SoNode * from) [virtual]Sets the catalog part given by partname to the from node pointer.

Reimplemented from SoBaseKit.

Referenced by SoSpotLightManip::fieldSensorCB(), SoPointLightManip::fieldSensorCB(), and SoDirectionalLightManip::fieldSensorCB().

SbBool SoInteractionKit::setPart (const int partnum, SoNode * node) [protected, virtual]Sets parts, updates nodekit scene graph, and makes sure graph is valid with respect to right siblings and parent. This method is virtual to enable subclasses to detect when a part changes value.

This method is not part of the original SGI Open Inventor API, but is an extension specific to Coin.

Reimplemented from SoBaseKit.

References SoBase::getName(), SoBaseKit::getNodekitCatalog(), and SoBaseKit::setPart().

SbBool SoInteractionKit::readInstance (SoInput * in, unsigned short flags) [protected, virtual]This method is mainly intended for internal use during file import operations.

It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE.

flags is used internally during binary import when reading user extension nodes, group nodes or engines.

Reimplemented from SoBaseKit.

void SoInteractionKit::readDefaultParts (const char * fileName, const char defaultBuffer[], int defBufSize) [static, protected]Reads default parts for a dragger.

This method is called from dragger constructors to set up a dragger's nodekit catalog of interaction and feedback geometry.

fileName is the user-changeable resource file in the Inventor file format, while defaultBuffer and defBufSize can point to the statically compiled default parts.

The environment variable SO_DRAGGER_DIR must be set to a valid directory prefix for fileName, or no resource file will be loaded (and defaultBuffer will be used instead).

If both a fileName and a defaultBuffer is provided, the file will be attempted found and loaded first, if that fails, the geometry will be attempted read from the buffer.

SbBool SoInteractionKit::setUpConnections (SbBool onoff, SbBool doitalways = 0) [protected, virtual]Sets up all internal connections for instances of this class.

void SoInteractionKit::setDefaultOnNonWritingFields (void) [protected, virtual](Be aware that this method is unlikely to be of interest to the application programmer who does not want to extend the library with new custom nodekits or draggers. If you indeed are writing extensions, see the information in the SoBaseKit class documentation.)

This is a virtual method, and the code in it should call SoField::setDefault() with argument TRUE on part fields that should not be written upon scenegraph export operations.

This is typically done when:

1.

field value is NULL and part is NULL by default

2.

it is a leaf SoGroup or SoSeparator node with no children

3.

it is a leaf listpart with no children and an SoGroup or SoSeparator container

4.

it is a non-leaf part and it's of SoGroup type and all fields are at their default values

Subclasses should usually override this to do additional settings for new member fields. From the subclass, do remember to call 'upwards' to your superclass' setDefaultOnNonWritingFields() method.
