Detailed Description

The SoTabBoxDragger wraps a box around geometry you can then translate and scale.

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

This dragger lets the end-user do translation and non-uniform scaling of geometry with an easy to understand interface.

Click and drag any side of the box to translate (hold down a SHIFT key to lock to one axis) and click and drag any of the tab markers in the corners to scale. The way the different tabs influences the scale operation should be straight-forward and intuitive to the end-user.

The SoTabBoxDragger is a composite dragger, implemented with 6 SoTabPlaneDragger instances set up as the sides of a box.

Constructor & Destructor Documentation

  SoTabBoxDragger::SoTabBoxDragger (void)
Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.

Node kit structure (new entries versus parent class marked with arrow prefix):

CLASS SoTabBoxDragger

      "topSeparator"
         "motionMatrix"
-->      "surroundScale"

  SoTabBoxDragger::~SoTabBoxDragger (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 SoTabBoxDragger::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 * SoTabBoxDragger::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 * SoTabBoxDragger::getNodekitCatalog (void) const [virtual]
Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoDragger.

  void SoTabBoxDragger::adjustScaleTabSize (void)
Signals the dragger to recalculate the size of its tabs.

Simply calls SoTabPlaneDragger::adjustScaleTabSize() for all 6 planes this dragger consists of.

  SbBool SoTabBoxDragger::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 SoTabBoxDragger::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.

  void SoTabBoxDragger::invalidateSurroundScaleCB (void * d, SoDragger * d) [static], [protected]
surroundScale is invalidated every time a child dragger is activated/deactivated using this callback

  void SoTabBoxDragger::fieldSensorCB (void * d, SoSensor * s) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

  void SoTabBoxDragger::valueChangedCB (void * f, SoDragger * d) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

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

  SoFieldSensor * SoTabBoxDragger::translFieldSensor [protected]

  SoFieldSensor * SoTabBoxDragger::scaleFieldSensor [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
