SoScale1Dragger(3)

📦 version 3.1.3, in fedora 43, fedora 44

okay so bestie, you've stumbled into the Library Functions Manual, and the star of today's episode is SoScale1Dragger. It's a Coin/Inventor class, it lives in the draggers folder, and it's about to become your whole personality. Buckle up, we're doing this in three parts and this is part one. 🎀

✨ NAME ✨

  • SoScale1Dragger — the class that hands the end-user a whole mechanism for scaling stuff in one single dimension. One. Uno. Just the one axis, no cap. 💅

🦋 SYNOPSIS 🦋

#include <Inventor/draggers/SoScale1Dragger.h>

Inherits SoDragger. So yes, it's getting that dragger inheritance energy, and it's giving everything SoDragger can do, plus its own thing. 🫶

💖 Public Member Functions 💖

  • virtual SoType getTypeId (void) const — the type-id getter, virtual, as is tradition. 👑
  • virtual const SoNodekitCatalog * getNodekitCatalog (void) const — hands you the nodekit catalog pointer. It's const, bestie, we respect boundaries here. ✨
  • SoScale1Dragger (void) — the constructor. No args, just vibes. 🌸

💖 Detailed Description 💖

okay so the SoScale1Dragger class is literally a whole mechanism that lets your end-user scale stuff in one dimension. iconic.

here's how the dragger looks with its default geometry when it's inactive:

use this dragger to let your app's end-user scale along the X-axis. (pro tip: put a transformation node in front of the dragger to position it and re-orient it so you can scale along any vector.)

SoScale2Dragger, SoScaleUniformDragger, SoScale2UniformDragger

🎀 Constructor & Destructor Documentation 🎀

🦋 SoScale1Dragger::SoScale1Dragger (void ) 🦋

the default constructor, bestie — it sets up the dragger nodekit catalog with the interaction and feedback geometry. no cap.

Node kit structure (new entries versus parent class marked with arrow prefix):

CLASS SoScale1Dragger
-->"this"
      "callbackList"
      "topSeparator"
         "motionMatrix"
         "geomSeparator"

-->         "feedbackSwitch"
-->            "feedback"
-->            "feedbackActive"

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

🦋 SoScale1Dragger::~SoScale1Dragger (void ) [protected], [virtual] 🦋

protected destructor. so don't touch unless you know what you're doing, bestie.

(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)

Member Function Documentation 💅

SoType SoScale1Dragger::getTypeId (void ) const [virtual]

Okay bestie, this one hands you the type identification of an object that derives from SoBase. It's literally for run-time type checking and "downward" casting. It's how you ask, "hey, what are you really?" and get a safe answer.

Usage example:

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

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. 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.

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

Reimplemented from SoDragger.

const SoFieldData * SoScale1Dragger::getFieldData (void ) const [protected], [virtual]

This returns a pointer to the class-wide field data storage object for this instance. If there are no fields present, it returns NULL. So either you get the goods or you get NULL, periodt.

Reimplemented from SoDragger.

const SoNodekitCatalog * SoScale1Dragger::getNodekitCatalog (void ) const [virtual]

Returns the nodekit catalog that defines the layout of this class' kit. It's giving "here's the blueprint for the whole kit and caboodle."

Reimplemented from SoDragger.

SbBool SoScale1Dragger::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 SoScale1Dragger::startCB (void * f, SoDragger * d) [static], [protected]

Okay, this API member is considered internal to the library — it is not likely to be of interest to the application programmer. Basically, if you're not deep in Coin's guts, you can scroll past.

void SoScale1Dragger::motionCB (void * f, SoDragger * d) [static], [protected]

Another API member that's considered internal to the library, so it is not likely to be of interest to the application programmer.

void SoScale1Dragger::finishCB (void * f, SoDragger * d) [static], [protected]

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

void SoScale1Dragger::fieldSensorCB (void * d, SoSensor * s) [static], [protected]

Internal API member alert: this is considered internal to the library, so it is not likely to be of interest to the application programmer.

void SoScale1Dragger::valueChangedCB (void * f, SoDragger * d) [static], [protected]

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

void SoScale1Dragger::dragStart (void ) [protected]

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

Called when dragger is selected (picked) by the user.

void SoScale1Dragger::drag (void ) [protected]

Member Data Documentation 🎀

SoSFVec3f SoScale1Dragger::scaleFactor

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

For the SoScale1Dragger, only the X component is used, the Y and Z components will always be equal to 1 (ie no scaling). So X is the main character here; Y and Z are just standing there at 1.
