The SoTranslate1Dragger class provides a mechanism for the end-user to translate along an axis.
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 translate along the X-axis and the Y-axis at the same time, ie freely inside a 3D plane. (Use a transformation node in front of the dragger to position it and re-orient it to translate in any plane.)
SoTranslate1Dragger::SoTranslate1Dragger | ( | 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 SoTranslate1Dragger -->"this" "callbackList" "topSeparator" "motionMatrix" "geomSeparator" --> "translatorSwitch" --> "translator" --> "translatorActive" --> "feedbackSwitch" --> "feedback" --> "feedbackActive"
(See SoBaseKit::printDiagram() for information about the output formatting.)
Detailed information on catalog parts:
CLASS SoTranslate1Dragger PVT "this", SoTranslate1Dragger --- "callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ] PVT "topSeparator", SoSeparator --- PVT "motionMatrix", SoMatrixTransform --- PVT "geomSeparator", SoSeparator --- PVT "translatorSwitch", SoSwitch --- "translator", SoSeparator --- "translatorActive", SoSeparator --- PVT "feedbackSwitch", SoSwitch --- "feedback", SoSeparator --- "feedbackActive", SoSeparator ---
(See SoBaseKit::printTable() for information about the output formatting.)
SoTranslate1Dragger::~SoTranslate1Dragger | ( | 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.)
void SoTranslate1Dragger::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 SoTranslate1Dragger::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 SoTranslate1Dragger::setMotionMatrix | ( | const SbMatrix & | matrix | ) | [protected, virtual] |
Sets a new current motion matrix for the dragger geometry.
Triggers value changed callbacks if matrix is unequal to the previous motion matrix.
Reimplemented from SoDragger.
void SoTranslate1Dragger::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 SoTranslate1Dragger::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 SoTranslate1Dragger::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 SoTranslate1Dragger::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 SoTranslate1Dragger::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 SoTranslate1Dragger::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 SoTranslate1Dragger::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 SoTranslate1Dragger::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 translation from the dragger's local origo position. Only the first component (the X value) can be changed by the end-user.
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.
Sets the minimum value allowed in the x component of the translaton field. This is only active if minTranslation <= maxTranslation.
Default value is 1.0
Sets the minimum value allowed in each component of the translaton field. This is only active if minTranslation <= maxTranslation for each component.
Default value is [1.0, 1.0]
Sets the maximum value allowed in the x component of the translaton field. This is only active if minTranslation <= maxTranslation.
Default value is 0.0.
Sets the maximum value allowed in each component of the translaton field. This is only active if minTranslation <= maxTranslation for each component.
Default value is [0.0, 0.0]
SoFieldSensor * SoTranslate1Dragger::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 * SoTranslate1Dragger::lineProj [protected] |
The SbLineProjector instance used for projecting from 2D mouse cursor positions to 3D points.
