Inheritance diagram for SoDragPointDragger:
Here's how the dragger looks with its default geometry in the inactive state:.
This dragger is convenient to use when it is desirable that the end-user should interact with points by positioning them freely in 3D space.
The dragger consists of a part for 2D motion in a plane (like the SoTranslate2Dragger) and another part on the axis normal to the plane.
While the dragger is inactive (ie the user is not currently grabbing and / or dragging it's parts), the CTRL keys on the keyboard can be used to switch the orientation of the 2D-plane part and the normal-axis part so the normal-axis part points along one of the other principal axes. This is done by position the mouse pointer over the dragger geometry and pressing and releasing a CTRL key.

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):

Protected destructor. (Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.) |
|
This static method returns the SoType object associated with objects of this class. Reimplemented from SoDragger. |
|
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 SoDragger. |

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. |

The dragger plane jump limit is ignored in Coin, as we use a continuous moving plane. This method still included for API compatibility with the original SGI Inventor API. |

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. |

(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 This is typically done when:
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. |

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. |
