SoInteraction(3) Coin SoInteraction(3) NAME
SoInteraction - The SoInteraction class takes care of initalizing internal classes. SoInteraction is present for the sole purpose of providing an interface to the initialization methods of the classes in Coin which are somehow related to user interaction, like the draggers and manipulators. SYNOPSIS
#include <Inventor/SoInteraction.h> Static Public Member Functions static void init (void) Detailed Description The SoInteraction class takes care of initalizing internal classes. SoInteraction is present for the sole purpose of providing an interface to the initialization methods of the classes in Coin which are somehow related to user interaction, like the draggers and manipulators. It is unlikely that the application programmer should need to worry about this class, as SoInteraction::init() is called by the GUI specific initialization methods. Member Function Documentation void SoInteraction::init (void) [static] Calls the initClass() method of these classes: SoAntiSquish, SoSelection, SoExtSelection, SoSurroundScale, SoInteractionKit, SoDragger, SoClipPlaneManip, SoDirectionalLightManip, SoPointLightManip, SoSpotLightManip, SoTransformManip, SoCenterballManip, SoHandleBoxManip, SoJackManip, SoTabBoxManip, SoTrackballManip, SoTransformBoxManip, SoTransformerManip. Note that this method calls SoDB::init() and SoNodeKit::init() to make sure all classes that the interaction functionality depends on have been initialized. Application programmers should usually not have to invoke this method directly from application code, as it is indirectly called from the GUI-binding libraries' init()-functions. Only if you are using your own GUI-binding (and not one of Kongsberg Oil & Gas Technologies SoQt, SoGtk, SoXt, SoWin, Sc21 etc. libraries) do you have to explicitly call SoInteraction::init(). int main(int argc, char ** argv ) { // SoQt::init() calls SoDB::init(), SoNodeKit::init() and // SoInteraction::init(). QWidget * window = SoQt::init( argv[0] ); SoSeparator * root = make_scenegraph(); root->ref(); /// [... etc ...] /// Author Generated automatically by Doxygen for Coin from the source code.

SoTrackballManip(3) Coin SoTrackballManip(3) NAME
SoTrackballManip - The SoTrackballManip wraps an SoTrackballDragger for convenience. SYNOPSIS
#include <Inventor/manips/SoTrackballManip.h> Inherits SoTransformManip. Public Member Functions virtual SoType getTypeId (void) const SoTrackballManip (void) Static Public Member Functions static SoType getClassTypeId (void) static void initClass (void) Protected Member Functions virtual const SoFieldData * getFieldData (void) const virtual ~SoTrackballManip (void) Static Protected Member Functions static const SoFieldData ** getFieldDataPtr (void) Additional Inherited Members Detailed Description The SoTrackballManip wraps an SoTrackballDragger for convenience. The manipulator class takes care of wrapping up the SoTrackballDragger in a simple and convenient API for the application programmer, making it automatically surround the geometry it influences and taking care of the book-keeping routines for it's interaction with the relevant fields of an SoTransformation node. Here's a dead simple, stand-alone example on how to set up an SoTrackballManip in a scenegraph: #include <Inventor/Qt/SoQt.h> #include <Inventor/Qt/viewers/SoQtExaminerViewer.h> #include <Inventor/nodes/SoCone.h> #include <Inventor/nodes/SoSeparator.h> #include <Inventor/manips/SoTrackballManip.h> int main(int argc, char* argv[]) { QWidget * mainwin = SoQt::init(argv[0]); SoSeparator * root = new SoSeparator; root->ref(); SoTrackballManip * manip = new SoTrackballManip; root->addChild(manip); root->addChild(new SoCone); SoQtExaminerViewer * viewer = new SoQtExaminerViewer(mainwin); viewer->setSceneGraph(root); SoQt::show(mainwin); SoQt::mainLoop(); root->unref(); return 0; } Compile and hit 'ESC' to go into scenegraph interaction mode in the examinerviewer, then change the rotation of the cone by interacting with the dragger bands. Constructor &; Destructor Documentation SoTrackballManip::SoTrackballManip (void) Default constructor. Allocates an SoTrackballDragger and an SoSurroundScale node to surround the geometry within our part of the scenegraph. SoTrackballManip::~SoTrackballManip (void) [protected], [virtual] Destructor. Member Function Documentation SoType SoTrackballManip::getClassTypeId (void) [static] This static method returns the SoType object associated with objects of this class. Reimplemented from SoTransformManip. SoType SoTrackballManip::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 SoTransformManip. const SoFieldData ** SoTrackballManip::getFieldDataPtr (void) [static], [protected] This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Reimplemented from SoTransformManip. const SoFieldData * SoTrackballManip::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 SoTransformManip. void SoTrackballManip::initClass (void) [static] Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
