Detailed Description

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

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

tabbox.png

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 -->"this" "callbackList" "topSeparator" "motionMatrix" --> "surroundScale" --> "tabPlane1Sep" --> "tabPlane1Xf" --> "tabPlane1" --> "tabPlane2Sep" --> "tabPlane2Xf" --> "tabPlane2" --> "tabPlane3Sep" --> "tabPlane3Xf" --> "tabPlane3" --> "tabPlane4Sep" --> "tabPlane4Xf" --> "tabPlane4" --> "tabPlane5Sep" --> "tabPlane5Xf" --> "tabPlane5" --> "tabPlane6Sep" --> "tabPlane6Xf" --> "tabPlane6" "geomSeparator" --> "boxGeom"

(See SoBaseKit::printDiagram() for information about the output formatting.)

SoTabBoxDragger::~SoTabBoxDragger  )  [protected]
 

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

void SoTabBoxDragger::initClass void   )  [static]
 

Initializes type system for this dragger class.

Application programmers should usually not have to invoke this method, see documentation of SoInteraction::init().

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.)

A virtual method that 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 a 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.

Reimplemented from SoInteractionKit.

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.
