The SoScale1Dragger class provides a mechanism for the end-user to scale in one dimension.
Here's how the dragger looks with its default geometry in the inactive state:
Use this dragger to allow the end-user of your application to scale along the X-axis. (Use a transformation node in front of the dragger to position it and re-orient it to scale along any vector.)
SoScale1Dragger::SoScale1Dragger | ( | 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 SoScale1Dragger -->"this" "callbackList" "topSeparator" "motionMatrix" "geomSeparator" --> "scalerSwitch" --> "scaler" --> "scalerActive" --> "feedbackSwitch" --> "feedback" --> "feedbackActive"
(See SoBaseKit::printDiagram() for information about the output formatting.)
Detailed information on catalog parts:
CLASS SoScale1Dragger PVT "this", SoScale1Dragger --- "callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ] PVT "topSeparator", SoSeparator --- PVT "motionMatrix", SoMatrixTransform --- PVT "geomSeparator", SoSeparator --- PVT "scalerSwitch", SoSwitch --- "scaler", SoSeparator --- "scalerActive", SoSeparator --- PVT "feedbackSwitch", SoSwitch --- "feedback", SoSeparator --- "feedbackActive", SoSeparator ---
(See SoBaseKit::printTable() for information about the output formatting.)
SoScale1Dragger::~SoScale1Dragger | ( | 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.)
SoType SoScale1Dragger::getClassTypeId | ( | void | ) | [static] |
SoType SoScale1Dragger::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 ** SoScale1Dragger::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 * SoScale1Dragger::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 * SoScale1Dragger::getClassNodekitCatalog | ( | void | ) | [static] |
Returns the nodekit catalog which defines the layout of this class' kit.
Reimplemented from SoDragger.
const SoNodekitCatalog * SoScale1Dragger::getNodekitCatalog | ( | void | ) | const [virtual] |
Returns the nodekit catalog which defines the layout of this class' kit.
Reimplemented from SoDragger.
const SoNodekitCatalog ** SoScale1Dragger::getClassNodekitCatalogPtr | ( | void | ) | [static, protected] |
Returns the pointer to the pointer of the nodekit catalog for this class.
Reimplemented from SoDragger.
void SoScale1Dragger::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.
SbBool SoScale1Dragger::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 SoScale1Dragger::startCB | ( | 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.
void SoScale1Dragger::motionCB | ( | 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.
void SoScale1Dragger::finishCB | ( | 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.
void SoScale1Dragger::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 SoScale1Dragger::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.
void SoScale1Dragger::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.
void SoScale1Dragger::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 SoScale1Dragger::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.
Continuously updated to contain the current vector of scaling along the X, Y and Z axes.
For the SoScale1Dragger, only the X component is used, the Y and Z components will always be equal to 1 (ie no scaling).
SoFieldSensor * SoScale1Dragger::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.
SbLineProjector * SoScale1Dragger::lineProj [protected] |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
