NAME
SoTrackballManip
SYNOPSIS
#include <Inventor/manips/SoTrackballManip.h> Inherits SoTransformManip.
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. - Public Member Functions

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 () [protected]
- 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}
else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {SoGroup * group = (SoGroup *)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.
- Reimplemented from SoTransformManip.
- Referenced by SoInteraction::init().
