💖 SoPointLightDragger 💖

okay so bestie, this is the manual page for SoPointLightDragger, a Coin class. And it is LONG. like, so long it comes in three parts, and this is part 1, so we are doing the NAME and the whole entire SYNOPSIS before we even breathe. the other parts are coming, do not close the tab. 💅✨

🎀 NAME 🎀

SoPointLightDragger — the class that gives you interactive geometry for manipulating a point light source. that's the whole job description. iconic. 🦋

🌸 SYNOPSIS 🌸

first things first, you gotta include the header or nothing works, periodt:

#include <Inventor/draggers/SoPointLightDragger.h>

and it Inherits SoDragger. so yeah, everything a dragger can do, this one can do too, it's giving nepo baby but in the best way. 💖

✨ Public Member Functions ✨

these are the ones that live on SoPointLightDragger itself, the main character members:

  • virtual SoType getTypeId (void) const — the type-id getter, virtual, const, very "know thyself" energy 🔍
  • virtual const SoNodekitCatalog * getNodekitCatalog (void) const — hands you the nodekit catalog, virtual and const, catalog girlie behavior 🗂️
  • SoPointLightDragger (void) — the constructor. no args, just vibes, ready to be built ✨

🔥 Detailed Description 🔥

The SoPointLightDragger class provides interactive geometry for manipulating a point light source. yes bestie, you literally grab it and move it around 💖

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

(there's a picture here of the dragger just vibing, default geometry, not active — you'd know it if you saw it) 🦋

This dragger is well suited to use for setting up the fields of a SoPointLight node, as it provides geometry for the end-user to translate a point in 3D space. it's giving "here's a handle, go wild" ✨

The Coin library also includes a manipulator class, SoPointLightManip, which wraps the functionality provided by this class inside the necessary mechanisms for connecting it to SoPointLight node instances in a scene graph. so like... this dragger is the raw vibe, and the manip is the same vibe but pre-wired into your scene graph, no cap 👑

  • SoPointLightManip

✨ Constructor & Destructor Documentation ✨

🎀 SoPointLightDragger::SoPointLightDragger (void )

okay so this is the default constructor, and what it does is set up the dragger nodekit catalog with the interaction geometry and the feedback geometry. both. it's giving overachiever 💅

here's the nodekit structure, and bestie pay attention bc the new entries versus the parent class are marked with an arrow prefix -->:

CLASS SoPointLightDragger
-->"this"
      "callbackList"
      "topSeparator"
         "motionMatrix"
-->      "material"
-->      "translator"
         "geomSeparator"

(if you wanna know more about how that output formatting works, go peek at SoBaseKit::printDiagram() — it's all in there 🫶)

and now the detailed info on the catalog parts, no skimping:

CLASS SoPointLightDragger
PVT   "this",  SoPointLightDragger  ---
      "callbackList",  SoNodeKitListPart [ SoCallback, SoEventCallback ]
PVT   "topSeparator",  SoSeparator  ---
PVT   "motionMatrix",  SoMatrixTransform  ---
      "material",  SoMaterial  ---
      "translator",  SoDragPointDragger  ---
PVT   "geomSeparator",  SoSeparator  ---

(and for how that output formatting works, see SoBaseKit::printTable() ✨)

🦋 SoPointLightDragger::~SoPointLightDragger (void ) [protected], [virtual]

protected destructor, bestie. it's the quiet exit.

and here's the lore: dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0. so like, you don't have to do anything, the vibes handle it themselves 😌

💖 Member Function Documentation 💖

🌸 SoType SoPointLightDragger::getClassTypeId (void ) [static]

this static method returns the SoType object associated with objects of this class. very demure, very static.

🌈 SoType SoPointLightDragger::getTypeId (void ) const [virtual]

returns the type identification of an object derived from a class inheriting SoBase. this is what's used for runtime type checking and for "downward" casting.

Reimplemented from SoDragger.

💅 const SoFieldData ** SoPointLightDragger::getFieldDataPtr (void ) [static], [protected]

ngl this API member is considered internal to the library, because it's not likely to be of interest to the application programmer. iykyk.

returns the SoFieldData class which holds information about fields in this node.

🎀 const SoFieldData * SoPointLightDragger::getFieldData (void ) const [protected], [virtual]

returns a pointer to the class-wide field data storage object for this instance. and if there are no fields present? it returns NULL. no fields, no problem.

Reimplemented from SoDragger.

⭐ const SoNodekitCatalog * SoPointLightDragger::getClassNodekitCatalog (void ) [static]

returns the nodekit catalog which defines the layout of this class' kit. it's literally the blueprint 🫶

🦋 const SoNodekitCatalog * SoPointLightDragger::getNodekitCatalog (void ) const [virtual]

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

Reimplemented from SoDragger.

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

returns the pointer to the pointer of the nodekit catalog for this class. yes bestie, a pointer to a pointer. double the pointer, double the power 💀

🔥 void SoPointLightDragger::initClass (void ) [static]

initializes the type system for this dragger class.

application programmers should usually not have to invoke this method — go read the documentation of SoInteraction::init() instead, it's the main character here 👑

💜 SbBool SoPointLightDragger::setUpConnections (SbBool onoff, SbBool doitalways = FALSE) [protected], [virtual]

sets up all internal connections for instances of this class.

(okay so this method will usually not be of interest to the application programmer — unless you're out here extending the library with new custom nodekits or dragger classes. if that's you, iconic, go see the SoBaseKit class documentation.)

Reimplemented from SoInteractionKit.

🍓 void SoPointLightDragger::setDefaultOnNonWritingFields (void ) [protected], [virtual]

heads up bestie: 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, go read the info 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. and from the subclass, do remember to call "upwards" to your superclass' setDefaultOnNonWritingFields() method — don't leave your parent hanging fr fr.

Reimplemented from SoDragger.

🧚 void SoPointLightDragger::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 SoPointLightDragger::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. (yes, same energy as the one above. they're a matching set 🎀)

💫 SoSFVec3f SoPointLightDragger::translation

this field is continuously updated to contain the translation of the point light dragger. the application programmer will typically connect this to the SoPointLight::location field of a SoPointLight node — unless you're using the SoPointLightManip class, where this is taken care of automatically. slay, no manual labor required 💅

and it may also of course be connected to any other location / translation field controlling the position of scene graph geometry. it does not have to be part of a SoPointLight node specifically. versatile queen ✨
