💖 NAME 💖

okay so welcome to SoScale2Dragger(3) — the Coin page for the SoScale2Dragger class, and she is literally the class that hands your end-user a whole mechanism for scaling things in two dimensions. that's the vibe. two. dimensions. 💅

🎀 SYNOPSIS 🎀

🌸 Detailed Description 🌸

ok so SoScale2Dragger is literally the glow-up tool for your scene: it gives the end-user a whole mechanism to scale in two dimensions. two. dimensions. not one, not three, two. we love a specific queen. 💅

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

🖼️ (that's the little picture of it chillin' in its default geometry, not doing anything, just vibing in the inactive state)

Use this dragger to let the end-user of your app scale along the X-axis and the Y-axis. Pro tip straight from the source: use a transformation node in front of the dragger to position it and re-orient it, so you can scale in any plane you want. ✨

And bestie, the scaling can be done in a non-uniform manner. meaning X and Y don't have to match. they can be different. they can be whatever. slay.

SoScale2Dragger::SoScale2Dragger (void )

The default constructor, and she's doing a lot on day one: sets up the dragger nodekit catalog with the interaction and feedback geometry. icon behavior honestly. 🫶

SoScale2Dragger::~SoScale2Dragger (void ) [protected], [virtual]

The protected destructor. very exclusive, very private. 🙈

Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0. so like… she leaves the party when nobody's looking at her anymore. respect.

✨ Member Function Documentation ✨

SoType SoScale2Dragger::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. it's the class's little name tag. 🏷️

SoType SoScale2Dragger::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. iykyk.

Reimplemented from SoDragger.

const SoFieldData ** SoScale2Dragger::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.

const SoFieldData * SoScale2Dragger::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. no fields? NULL. she said "nothing here, moving on." 💀

Reimplemented from SoDragger.

const SoNodekitCatalog * SoScale2Dragger::getClassNodekitCatalog (void ) [static]

Returns the nodekit catalog which defines the layout of this class' kit. it's the blueprint bestie. 📐

const SoNodekitCatalog * SoScale2Dragger::getNodekitCatalog (void ) const [virtual]

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

Reimplemented from SoDragger.

const SoNodekitCatalog ** SoScale2Dragger::getClassNodekitCatalogPtr (void ) [static], [protected]

Returns the pointer to the pointer of the nodekit catalog for this class. yes, pointer to the pointer. double the pointer, double the drama. ✨

void SoScale2Dragger::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, hands off unless you know why. 👑

SbBool SoScale2Dragger::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. (that's the "you're built different, go read the big doc" moment fr fr)

Reimplemented from SoInteractionKit.

void SoScale2Dragger::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 SoScale2Dragger::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 SoScale2Dragger::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 SoScale2Dragger::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 SoScale2Dragger::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 SoScale2Dragger::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. 🫵 the moment the user locks eyes with her.

void SoScale2Dragger::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. 🖱️ the main character moment.

void SoScale2Dragger::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. that's a wrap, bestie. 🎬

👑 Member Data Documentation 👑

SoSFVec3f SoScale2Dragger::scaleFactor

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

For the SoScale2Dragger, only the X and Y components are used, the Z component will always be equal to 1 (i.e. no scaling). Z is literally just there to hold X and Y's bags. 💅

SoFieldSensor* SoScale2Dragger::fieldSensor [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

SbPlaneProjector* SoScale2Dragger::planeProj [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
