Public Types inherited from SoNode 💜

okay so before we even get into the dragger's own glow-up, bestie needs to know what it inherited from SoNode. And it's a whole enum, and it is long, and I am obsessed:

enum NodeType { INVENTOR = 0x0000, VRML1 = 0x0001, VRML2 = 0x0002,
    INVENTOR_1 = 0x0004, INVENTOR_2_0 = 0x0008, INVENTOR_2_1 = 0x0010,
    INVENTOR_2_5 = 0x0020, INVENTOR_2_6 = 0x0040, COIN_1_0 = 0x0080,
    COIN_2_0 = 0x0100, EXTENSION = 0x0200, COIN_2_2 = 0x0400, COIN_2_3 =
    0x0800, COIN_2_4 = 0x1000, INVENTOR_5_0 = 0x2000, COIN_2_5 = 0x4000,
    COIN_3_0 = 0x8000, INVENTOR_6_0 = 0x10000, COIN_4_0 = 0x20000 }

every single one of those hex values is staying right where it is, no cap. 🫶

and from SoBase we got a lil' baby enum too:

enum BaseFlags { IS_ENGINE = 0x01, IS_GROUP = 0x02 }

two flags, both iconic, both exactly 0x01 and 0x02, don't touch them. ✨

the static protected attr-ies, carried down like family heirlooms:

  • static int nextActionMethodIndex = 0 — and this one starting at 0

Detailed Description 🌈✨

okay so what does this thing even DO. The SoDragPointDragger class provides mechanisms for moving a point in 3D. that's it, that's the whole vibe — a point, in 3D, moved by you. 💅

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

This dragger is convenient to use when it is desirable that the end-user should interact with points by positioning them freely in 3D space. 🫶 free positioning, no rules, main character energy fr fr.

The dragger consists of a part for 2D motion in a plane (like the SoTranslate2Dragger) and another part on the axis normal to the plane. so: one slice for sliding around flat, one slice for sliding up out of the plane. 🧚

And here's the cute trick: While the dragger is inactive (i.e. the user is not currently grabbing and / or dragging its parts), the CTRL keys on the keyboard can be used to switch the orientation of the 2D-plane part and the normal-axis part so the normal-axis part points along one of the other principal axes. This is done by position the mouse pointer over the dragger geometry and pressing and releasing a CTRL key. yes — hover, tap CTRL, and the whole orientation flips to a different principal axis. lowkey magical. ✨

SoDragPointDragger::~SoDragPointDragger (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 don't you dare think about deleting it manually, bestie — let the refcount do its thing. 🫶

💅 Member Function Documentation 💅

okay bestie, this is the big one — every single method this dragger has. no skips, no "you get the idea". we're going through ALL of them. grab a snack 🍓

SoType SoDragPointDragger::getClassTypeId (void )

  • [static]

this static method returns the SoType object that's associated with objects of this class. that's it. that's the whole job. 💖

SoType SoDragPointDragger::getTypeId (void ) const

  • [virtual]

returns the type identification of an object derived from a class inheriting SoBase. this is the whole runtime-type-checking-and-"downward"-casting situation — that's literally what it's for.

Reimplemented from SoDragger.

const SoFieldData ** SoDragPointDragger::getFieldDataPtr (void )

  • [static], [protected]

okay so real talk, 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 * SoDragPointDragger::getFieldData (void ) const

  • [protected], [virtual]

returns a pointer to the class-wide field data storage object for this instance. if no fields are present, it returns NULL. yes, actual NULL, not a vibe. 😭

Reimplemented from SoDragger.

const SoNodekitCatalog * SoDragPointDragger::getClassNodekitCatalog (void )

  • [static]

returns the nodekit catalog which defines the layout of this class' kit. it's giving floor plan but for nodekits. ✨

const SoNodekitCatalog * SoDragPointDragger::getNodekitCatalog (void ) const

  • [virtual]

returns the nodekit catalog which defines the layout of this class' kit. same energy as above, just for the instance. 🫶

Reimplemented from SoDragger.

const SoNodekitCatalog ** SoDragPointDragger::getClassNodekitCatalogPtr (void )

  • [static], [protected]

returns the pointer to the pointer of the nodekit catalog for this class. double pointer. two stars. it's iconic, it's terrifying, it's **. ⭐

void SoDragPointDragger::initClass (void )

  • [static]

initializes the type system for this dragger class.

application programmers should usually not have to invoke this method — see the documentation of SoInteraction::init() for the actual tea. 🎀

void SoDragPointDragger::setJumpLimit (const float limit)

the dragger plane jump limit is ignored in Coin, as we use a continuous moving plane.

this method is still included for API compatibility with the original SGI Inventor API. so like… it exists. it's there. it does nothing. main character who shows up to the party and just stands there. 💀

float SoDragPointDragger::getJumpLimit (void ) const

the dragger plane jump limit is ignored in Coin, as we use a continuous moving plane.

this method is still included for API compatibility with the original SGI Inventor API. matching set with setJumpLimit(), no cap. 👑

void SoDragPointDragger::showNextDraggerSet (void )

circulate the dragger's three different sets of geometry, to circulate the orientation of the translation axis and translation plane through the three principal axes.

this function is triggered when the user taps the CTRL key. that's the whole hotkey lore, bestie. ⌨️✨

SbBool SoDragPointDragger::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 SoDragPointDragger::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 be rude, call your ancestors. 🫶

Reimplemented from SoDragger.

void SoDragPointDragger::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 the dragger is selected (picked) by the user. 👆

void SoDragPointDragger::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 the user drags the mouse after picking the dragger. 🖱️

void SoDragPointDragger::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 the mouse button is released after picking and interacting with the dragger. the mouse button said "and that's on periodt." 💅

void SoDragPointDragger::startCB (void * d, 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 SoDragPointDragger::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 SoDragPointDragger::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 🌈

SoSFVec3f SoDragPointDragger::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. fr fr, connect it or it won't follow, that's the deal. 🦋

SoFieldSensor* SoDragPointDragger::fieldSensor

  • [protected]

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