Detailed Description 📖

The SoPointLightDragger class provides interactive geometry for manipulating a point light source. literally its whole personality.

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

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 "drag the light around and watch the world relight itself."

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 scenegraph. so if you want the whole connected-to-a-node thing done for you, that's the one, bestie.

Constructor & Destructor Documentation 🛠️

`SoPointLightDragger::SoPointLightDragger (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 SoPointLightDragger
-->"this"
      "callbackList"
      "topSeparator"
         "motionMatrix"
-->      "material"
-->      "translator"
         "geomSeparator"

(See SoBaseKit::printDiagram() for information about the output formatting.)

Detailed information on catalog parts:

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

(See SoBaseKit::printTable() for information about the output formatting.)

`SoPointLightDragger::~SoPointLightDragger (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 like, don't go delete-ing it yourself, the refcounting has it handled.

💖 Member Function Documentation 💖

okay bestie, this is the part where we meet the actual methods, the little guys doing the work behind the scenes. strap in, there's a lot of them and they're all iconic in their own way ✨

`getTypeId` 🦋

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

Returns the type identification of an object derived from a class inheriting SoBase. Basically it's the name tag moment — this is what gets used for run-time type checking and "downward" casting, iykyk 👑

Usage example, and yes you're getting it verbatim because it's literally the whole point:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

So for application programmers who wanna extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. fr fr, no skipping it. 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. macros doing the heavy lifting so you don't have to 💅

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoDragger.

`getFieldData` 🎀

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. that's it, that's the whole vibe 🌸

Reimplemented from SoDragger.

`getNodekitCatalog` ⭐

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

Returns the nodekit catalog which defines the layout of this class' kit. it's giving interior design blueprint but for nodekits 🫶

Reimplemented from SoDragger.

`setUpConnections` 🔥

SbBool SoPointLightDragger::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.)

so like... if you're just vibing and using the library, this is not your moment. if you're out here building custom nodekits or draggers, go read SoBaseKit bestie 📚

Reimplemented from SoInteractionKit.

`setDefaultOnNonWritingFields` 💀

void SoPointLightDragger::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 scenegraph export operations.

This is typically done when:

field value is NULL and part is NULL by default
it is a leaf SoGroup or SoSeparator node with no children
it is a leaf listpart with no children and an SoGroup or SoSeparator container
it is a non-leaf part and it's 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 class hanging, that's so rude 🙈

Reimplemented from SoDragger.

`fieldSensorCB` 🧚

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. so like, nothing to see here, keep scrolling bestie 💅

`valueChangedCB` 🌈

void SoPointLightDragger::valueChangedCB (void * f, SoDragger * d) [static],
    [protected]

Same energy, same warning: this API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈

`translation` 👑

SoSFVec3f SoPointLightDragger::translation

This field is continuously updated to contain the translation of the pointlight dragger. like it's literally always tracking where the dragger is at, main character energy fr.

The application programmer will typically connect this to the SoPointLight::location field of a SoPointLight node — (unless using the SoPointLightManip class, where this is taken care of automatically). so if you're on SoPointLightManip, you can just sit back and let it handle itself, slay ✨

It may also of course be connected to any other location / translation field controlling the position of scenegraph geometry, it does not have to part of a SoPointLight node specifically. freedom, options, versatility — we love to see it 🌸
