NAME
SoDragPointDragger
SYNOPSIS
#include <Inventor/draggers/SoDragPointDragger.h> Inherits SoDragger.
Detailed Description
The SoDragPointDragger class provides mechanisms for moving a point in
3D.
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 enduser 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. - Public Member Functions

Member Function Documentation
- SoType SoDragPointDragger::getClassTypeId (void) [static]
- This static method returns the SoType object associated with objects of this class.
- Reimplemented from SoDragger.
- SoType SoDragPointDragger::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}
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.
- const SoFieldData ** SoDragPointDragger::getFieldDataPtr (void) [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 SoDragger.
- const SoFieldData * SoDragPointDragger::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 * SoDragPointDragger::getClassNodekitCatalog (void)
- [static]
Returns the nodekit catalog which defines the layout of this class'
kit. - Reimplemented from SoDragger.
- const SoNodekitCatalog * SoDragPointDragger::getNodekitCatalog (void) const
- [virtual]
Returns the nodekit catalog which defines the layout of this class'
kit. - Reimplemented from SoDragger.
- const SoNodekitCatalog ** SoDragPointDragger::getClassNodekitCatalogPtr
- (void) [static, protected]
Returns the pointer to the pointer of the nodekit catalog for this
class. - Reimplemented from SoDragger.
- void SoDragPointDragger::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 SoDragPointDragger::setJumpLimit (const float limit)
- 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.
- float SoDragPointDragger::getJumpLimit (void) const
- 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.
- void SoDragPointDragger::showNextDraggerSet (void)
- Circulate the dragger's three different sets of geometry, to circulate
the orientation of the translation axis and translation plane through
the three principal axes. - This function is triggered when the user taps the CTRL key.
- Referenced by metaKeyChangeCB().
- SbBool SoDragPointDragger::setUpConnections (SbBool onoff, SbBool
- doitalways = 0) [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 SoDragPointDragger::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 SoDragPointDragger::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.
References SoInteractionKit::setSwitchValue(). - void SoDragPointDragger::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 SoDragPointDragger::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 SoDragPointDragger::startCB (void * d, 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. - void SoDragPointDragger::motionCB (void * d, SoDragger * d) [static,

Member Data Documentation
- SoSFVec3f SoDragPointDragger::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.
Referenced by valueChangedCB(). - SoFieldSensor * SoDragPointDragger::fieldSensor [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.
