Detailed Description

The SoTrackballDragger provides the end-user with rotation and scaling interaction possibilities.

Here's how the dragger looks with its default geometry in the inactive state:

The dragger has three "bands" around a transparent sphere, which when clicked and dragged will rotate around the three principal axes. In addition, the user can define his own rotation axis by holding down a SHIFT key while clicking with the left mouse button and dragging. A new, distinctively colored axis and dragger band will be then be added.

Free-form rotation on the sphere can be done by clicking and dragging outside the pre-defined "rotation bands".

Scale operations are made available by holding down a CTRL key when clicking with the left mouse button. The dragger is then in scaling mode, and dragging while holding down the mouse button will uniformly scale the trackball sphere.

For the application programmer's convenience, the Coin library also provides a manipulator class called SoTrackballManip, which wraps the SoTrackballDragger into the necessary mechanisms for making direct insertion of this dragger into a scenegraph possible with very little effort.

SoTrackballDragger::~SoTrackballDragger ( void )

protectedvirtual

Protected destructor.

(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)

Member Function Documentation

SoType SoTrackballDragger::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 SoDragger.

const SoFieldData * SoTrackballDragger::getFieldData ( void ) const

protectedvirtual

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 SoNodekitCatalog * SoTrackballDragger::getNodekitCatalog ( void ) const

virtual

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

Reimplemented from SoDragger.

SbBool SoTrackballDragger::isAnimationEnabled ( void )

Whether or not the trackball will start a spin animation after a quick drag-and-release.

Note: this feature is not supported yet in the Coin library, so even though if TRUE is returned, spin animations will not be possible to trigger.

void SoTrackballDragger::setAnimationEnabled ( SbBool newval )

Set a flag which will decide whether or not the trackball will start a spin animation after a quick drag-and-release.

Note: this feature is not supported yet in the Coin library.

SbBool SoTrackballDragger::setUpConnections	(	SbBool	onoff,
		SbBool	doitalways = `FALSE`
	)

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.)

Reimplemented from SoInteractionKit.

void SoTrackballDragger::setDefaultOnNonWritingFields ( void )

protectedvirtual

(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:

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'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.

Reimplemented from SoDragger.

void SoTrackballDragger::dragStart ( void )

protected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Called when dragger is selected (picked) by the user.

void SoTrackballDragger::drag ( void )

protected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Called when user drags the mouse after picking the dragger.

void SoTrackballDragger::dragFinish ( void )

protected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Called when mouse button is released after picking and interacting with the dragger.

void SoTrackballDragger::setAllPartsActive ( SbBool onoroff )

protected

If the input argument is TRUE, all the geometry parts of the dragger will become highligthed, as when active.

Used internally during scaling operations and free-form rotations.

Member Data Documentation

SoSFRotation SoTrackballDragger::rotation

This field is continuously updated to contain the rotation of the dragger's trackball.

SoSFVec3f SoTrackballDragger::scaleFactor

Continuously updated to contain the current vector of scaling along the X, Y and Z axes. The three components will always be equal, as this dragger only supports uniform scale operations.

SoFieldSensor * SoTrackballDragger::rotFieldSensor
