💖 SoJackDragger(3) — Coin 💖

okay bestie, buckle UP, because we're reading the SoJackDragger(3) page together and it's a whole journey. ✨

🎀 NAME 🎀

SoJackDragger — the dragger class you can translate, rotate and scale. all three. at once. it's giving overachiever and honestly? we love her for it. 💅

🦋 SYNOPSIS 🦋

#include <Inventor/draggers/SoJackDragger.h>

Inherits SoDragger. 🫶 (so everything her mama SoDragger can do, she can do too — and mama has a lot.)

✨ Public Member Functions ✨

these are the ones that are actually hers, the main character moves:

  • virtual SoType getTypeId (void) const — the runtime type check, so you can be like "hey are you actually a SoJackDragger?"
  • virtual const SoNodekitCatalog * getNodekitCatalog (void) const — hands you the nodekit catalog for this class. it's the blueprint of what parts live inside her.
  • SoJackDragger (void) — the constructor, aka her origin story. 🌸

💖 DETAILED DESCRIPTION 💖

okay so bestie, the SoJackDragger class is a dragger that you can translate, rotate and scale. it's giving multitasking icon behavior fr fr 💅

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

Translation is done with this dragger by picking the flat transparent box ("x-z" translation) or the solid middle part of the axis ("y"-axis translation). Press a SHIFT-key while translating in x-z to constrain to one of the principal axes. lowkey a glow-up for precision ✨

Uniform scale operations can be done by dragging any of the 6 cubes. Non-uniform scale operations cannot be done with this dragger. periodt. 🎀

Rotations are invoked by clicking and dragging the line parts of the 3 principal "axes" of the dragger geometry.

NB: How to rotate the dragger might be a bit unintuitive for the end user. If the dragger is to be used 'out of the box', a good documentation should be added to your application. An alternative is to modify the geometry to increase the affordance of the dragger. See the SoDragger documentation on how to change the geometry of a dragger. no cap, tell your users how it works or they will be lost 😭

An "action shot" of the SoJackDragger used within an SoClipPlaneManip:

The name "Jack dragger" probably stems from this dragger being implemented by SGI for interacting with a "jack-in-the-box" type model way back in the Inventor history. the lore?? immaculate 🎁

For programmer convenience, this dragger comes fully wrapped within instances of the SoJackManip class. The SoClipPlaneManip manipulator also uses this dragger, for controlling an SoClipPlane node. convenient much? 💜

SoJackDragger::~SoJackDragger (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.) so you don't gotta manually delete it, the reference count handles the drama 🫶

🧚 Member Function Documentation 🧚

SoType SoJackDragger::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class.

SoType SoJackDragger::getTypeId (void ) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Reimplemented from SoDragger.

const SoFieldData ** SoJackDragger::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.

Returns the SoFieldData class which holds information about fields in this node. iykyk, it's an internal thing bestie, don't worry about it 💜

const SoFieldData * SoJackDragger::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 * SoJackDragger::getClassNodekitCatalog (void ) [static]

Returns the nodekit catalog which defines the layout of this class' kit.

const SoNodekitCatalog * SoJackDragger::getNodekitCatalog (void ) const [virtual]

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoDragger.

const SoNodekitCatalog ** SoJackDragger::getClassNodekitCatalogPtr (void ) [static], [protected]

Returns the pointer to the pointer of the nodekit catalog for this class.

void SoJackDragger::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(). so like, don't touch unless you know what you're doing okay? 😌

SbBool SoJackDragger::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 SoJackDragger::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 scene graph 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 is 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. don't forget the upward call, that's the rule bestie 💙

Reimplemented from SoDragger.

void SoJackDragger::invalidateSurroundScaleCB (void * f, SoDragger * d) [static], [protected]

Used to invalidate the surroundScale and antiSquish parts when a child dragger starts or finishes dragging. keeping those parts fresh, no stale vibes allowed ✨

void SoJackDragger::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.

void SoJackDragger::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.

👑 Member Data Documentation 👑

SoSFRotation SoJackDragger::rotation

This field is continuously updated to contain the rotation of the current direction vector of the dragger. it's literally always tracking the rotation, main character energy fr 💅

SoSFVec3f SoJackDragger::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. hook it up so the scene follows along, periodt 🫶

SoSFVec3f SoJackDragger::scaleFactor

Continuously updated to contain the current vector of scaling along the X, Y and Z axes.

Only uniform scaling can be done with the SoJackDragger, so the 3 vector components will always be equal. all three matching? that's the uniform aesthetic 💚
