Detailed Description

The SoHandleBoxDragger class provides support for interactive scaling and translation.

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

A handlebox dragger is convenient to use for letting the user interact with geometry that can be scaled (uniformly or in a non-uniform way) and translated in 3D.

The dragger consists of a 'cube' of interaction geometry. The end-user can click and drag any side of the cube to translate the dragger and click and drag any of the corner or edge markers for scaling operations.

Constructor & Destructor Documentation

SoHandleBoxDragger::SoHandleBoxDragger (void)

Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.

SoHandleBoxDragger::~SoHandleBoxDragger (void) [protected], [virtual]

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 SoHandleBoxDragger::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 * SoHandleBoxDragger::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 SoDragger.

const SoNodekitCatalog * SoHandleBoxDragger::getNodekitCatalog (void) const [virtual]

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

Reimplemented from SoDragger.

SbBool SoHandleBoxDragger::setUpConnections (SbBool onoff, SbBool doitalways = FALSE) [protected], [virtual]

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 SoHandleBoxDragger::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.

Reimplemented from SoDragger.

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 SoHandleBoxDragger::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 SoHandleBoxDragger::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 SoHandleBoxDragger::setAllPartsActive (SbBool onoroff) [protected]

Activate or deactive all dragger geometry parts.

Member Data Documentation

SoSFVec3f SoHandleBoxDragger::scaleFactor

Continuously updated to contain the current vector of scaling along the X, Y and Z axes.

SoSFVec3f SoHandleBoxDragger::translation

Continuously updated to contain the current translation from the dragger's local origo position.

The application programmer applying this dragger in his code should connect the relevant node fields in the scene to this field to make it follow the dragger.

SoFieldSensor * SoHandleBoxDragger::translFieldSensor [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

SoFieldSensor * SoHandleBoxDragger::scaleFieldSensor [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
