SoScale2UniformDragger(3) · Library Functions Manual

okay bestie, sit down, hydrate, because we're about to get into a dragger. not like a dramatic person (well, also that), but a node that lets your end user grab stuff and scale it in two dimensions. let's go 🫶

💖 NAME 💖

SoScale2UniformDragger — the SoScale2UniformDragger class is the whole entire mechanism that hands your end-user the power to scale things in two dimensions. that's the vibe. that's the job. 🎀

🌸 SYNOPSIS 🌸

#include <Inventor/draggers/SoScale2UniformDragger.h>

Inherits SoDragger.

so yeah, it's a SoDragger at heart — which means it comes with a lot of family, and we're about to list every single one of them because we don't skip. no cap. 😤

💖 Detailed Description 💖

okay so here's the actual tea ☕

The SoScale2UniformDragger class provides a mechanism for the end-user to scale in two dimensions.

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

(there's a pic in the original page showing exactly that — default geometry, inactive, just vibing 🎀)

Use this dragger to allow the end-user of your application to scale along the X-axis and the Y-axis. (Use a transformation node in front of the dragger to position it and re-orient it to scale in any plane.)

Scaling with this dragger can only be done in a uniform manner, ie the X component of the SoScale2UniformDragger::scaleFactor will always equal the Y component. no exceptions bestie, that's literally the whole bit 💅

For non-uniform scaling operations in 2 dimensions, use the SoScale2Dragger.

🎀 Constructor & Destructor Documentation 🎀

SoScale2UniformDragger::SoScale2UniformDragger (void )

Okay bestie, this is the default constructor — 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):

SoScale2UniformDragger::~SoScale2UniformDragger (void ) [protected], [virtual]

Protected destructor. Periodt.

(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 SoScale2UniformDragger::getTypeId (void ) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting. Iykyk.

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 * SoScale2UniformDragger::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.

Reimplemented from SoDragger.

const SoNodekitCatalog * SoScale2UniformDragger::getNodekitCatalog (void ) const [virtual]

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

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.

Called when mouse button is released after picking and interacting with the dragger.

🦋 Member Data Documentation 🦋

SoSFVec3f SoScale2UniformDragger::scaleFactor

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

For the SoScale2UniformDragger, only the X and Y components are used, the Z component will always be equal to 1 (ie no scaling).

SoFieldSensor* SoScale2UniformDragger::fieldSensor [protected]

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

SbLineProjector* SoScale2UniformDragger::lineProj [protected]

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