SoInteraction(3)

✨ SoInteraction ✨

okay bestie, we're looking at SoInteraction(3) from the Coin manual — yes, that Coin, the 3D graphics toolkit one, not your grandma's coin purse 🪙💖

---

🌸 NAME 🌸

SoInteraction — the class that takes care of initializing internal classes. that's it, that's the whole job description, and it EATS 💅

---

🦋 SYNOPSIS 🦋

#include <Inventor/SoInteraction.h>

Static Public Member Functions

• static void init (void) — the one (1) function, the moment, the icon 👑

---

💖 Detailed Description 💖

The SoInteraction class takes care of initializing internal classes. say it with me: init. the. internal. classes. 🎀

SoInteraction is literally just here to be the interface to the initialization methods of the classes in Coin that are somehow related to user interaction — like the draggers and the manipulators. that's the whole vibe. it's giving backstage crew at the award show, no cap 🏆

ngl, it is unlikely that the application programmer should need to worry about this class, because SoInteraction::init() is called by the GUI-specific initialization methods. so like. it's already handled for you, bestie. breathe. 🫶

🌈 Member Function Documentation 🌈

🌟 void SoInteraction::init (void ) [static] 🌟

This method calls the initClass() method of these classes, and yes I'm listing every single one because we do NOT skip the roster:

• SoAntiSquish
• SoSelection
• SoExtSelection
• SoSurroundScale
• SoInteractionKit
• SoDragger
• SoClipPlaneManip
• SoDirectionalLightManip
• SoPointLightManip
• SoSpotLightManip
• SoTransformManip
• SoCenterballManip
• SoHandleBoxManip
• SoJackManip
• SoTabBoxManip
• SoTrackballManip
• SoTransformBoxManip
• SoTransformerManip

look at that lineup. all of them. every single one. the whole squad showed up and they're all getting their initClass() called 📣✨

heads up bestie: this method also calls SoDB::init() and SoNodeKit::init() to make sure all the classes that the interaction functionality depends on have been initialized. it's a whole chain, it's giving dependency management, it's giving "don't worry I already called them" 💅

Application programmers should usually not have to invoke this method directly from application code, because it's indirectly called from the GUI-binding libraries' init()-functions. 🎀

Only if you're using your own GUI-binding — and not one of the Kongsberg Oil & Gas Technologies SoQt, SoGtk, SoXt, SoWin, Sc21 etc. libraries — do you have to explicitly call SoInteraction::init(). iykyk 😌

here's the example, verbatim, no notes:

int main(int argc, char ** argv )
{
  // SoQt::init() calls SoDB::init(), SoNodeKit::init() and
  // SoInteraction::init().
  QWidget * window = SoQt::init( argv[0] );

  SoSeparator * root = make_scenegraph();
  root->ref();
