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.
Nodekit structure (new entries versus parent class marked with arrow prefix):
CLASS SoInteractionKit
-->"this"
"callbackList"
--> "topSeparator"
--> "geomSeparator"
(See SoBaseKit::printDiagram() for information about the output formatting.)
Detailed information on catalog parts:
CLASS SoInteractionKit
PVT "this", SoInteractionKit ---
"callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ]
PVT "topSeparator", SoSeparator ---
PVT "geomSeparator", SoSeparator ---
(See SoBaseKit::printTable() for information about the output formatting.)
Enumeration 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.

Makes a deep copy of all data of from into this instance, except external scene graph references if copyconnections is FALSE.
This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which need to account for internal data that are not handled automatically.
For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:
The same also goes for engines.
Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to its parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
| SbBool SoInteractionKit::isPathSurrogateInMySubgraph | ( | const SoPath * | path, |
| SoPath *& | pathToOwner, | ||
| SbName & | surrogatename, | ||
| SoPath *& | surrogatepath, | ||
| SbBool | fillargs = TRUE ) |
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.

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 are provided, the file will be attempted found and loaded first, if that fails, the geometry will be attempted read from the buffer.
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 / persistent 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.

("The nice thing about C++ is that only your friends can handle your private parts.")
(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 scene graph export operations.
This is typically done when:
field value is NULL and part is NULL by default
it is a leaf SoGroup or SoSeparator node with no children
it is a leaf listpart with no children and an SoGroup or SoSeparator container
it is a non-leaf part and it is 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.

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.

Sets the catalog part given by partname to the from node pointer.

|
virtual |
Find node in the global dictionary, and set as default.
|
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.
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.
Convenience method that sets the switch value for a switch node. Checks if node != 0, and only sets the switch value if value has changed.

protectedvirtual |
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.)
