SoDragPointDragger(3)

📦 version 2.5.0, in fedora 43, fedora 44

💖 SoDragPointDragger 💖

okay bestie, gather round, because this is SoDragPointDragger(3) from the Library Functions Manual, and it's genuinely one of the slay-est little draggers in the whole Coin/Inventor universe. ✨

🌸 NAME 🌸

SoDragPointDragger — the class that hands you the actual mechanisms for moving a point around in 3D. like, in space. three dimensions. iconic behaviour only. 💅

🦋 SYNOPSIS 🦋

First things first, the summoning spell:

#include <Inventor/draggers/SoDragPointDragger.h>

Inherits SoDragger. yes bestie, it's giving dragger family lineage, and we love a class that knows its ancestors. 👑

💅 DETAILED DESCRIPTION 💅

so like, what does SoDragPointDragger actually DO? The class provides mechanisms for moving a point in 3D. that's the whole vibe. 🎀

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

(picture it, bestie — that's the image from the original page showing her default geometry just chilling, inactive ✨)

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. lowkey perfect for that.

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. two parts, one iconic duo 🫶

While the dragger is inactive (ie the user is not currently grabbing and / or dragging it's 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. 👑

ngl that CTRL-key thing only works while she's inactive — once someone's grabbing or dragging her parts, that's a different story, so don't come for me 😭

✨ Constructor & Destructor Documentation ✨

Lowkey the most important part, bestie — this is where the dragger actually gets built. Let's get into it. 🛠️

`SoDragPointDragger::SoDragPointDragger`</p> `(void)`

Okay so this is the default constructor, and what it does is set up the dragger nodekit catalog with all the interaction and feedback geometry. Like, it's assembling the whole vibe from scratch. 🎀

Want the deets on that output formatting? That's SoBaseKit::printTable(). 🫶

References — bestie this constructor is social, it pulls in a whole friend group: SoDragger::addFinishCallback(), SoDragger::addMotionCallback(), SoDragger::addOtherEventCallback(), SoDragger::addStartCallback(), SoDragger::addValueChangedCallback(), fieldSensor, fieldSensorCB(), finishCB(), metaKeyChangeCB(), motionCB(), SoInteractionKit::readDefaultParts(), SoRotation::rotation, SoInteractionKit::setAnyPartAsDefault(), SoInteractionKit::setPartAsDefault(), SoInteractionKit::setSwitchValue(), setUpConnections(), SoDragPointDragger(), startCB(), translation, and valueChangedCB().

And it's also referenced by a bunch of them: fieldSensorCB(), finishCB(), getFieldData(), metaKeyChangeCB(), motionCB(), SoDragPointDragger(), startCB(), and valueChangedCB(). Mutuals fr fr. 😭💖

`SoDragPointDragger::~SoDragPointDragger` `()` [protected]

The protected destructor, bestie. It's giving backstage only energy. 🙈

Quick reminder: dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0. So like… no manual cleanup needed, she handles herself. 💅✨

✨ Member Function Documentation ✨

💖 `SoType SoDragPointDragger::getTypeId (void) const` [virtual]

okay bestie, this one hands you back the type identification of an object that derives from a class inheriting SoBase. What's it for? Run-time type checking and "downward" casting, that's what. ✨

Usage example, and yes you're gonna want to screenshot this:

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

So for application programmers who wanna extend the library with new nodes, engines, nodekits, draggers or others — listen up — this method needs to be overridden in all subclasses. It's 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. 🫶

🔁 Reimplemented from SoDragger.

🌸 `const SoFieldData * SoDragPointDragger::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 at all? It returns NULL. That's it, that's the whole vibe. 🙈

🔁 Reimplemented from SoDragger. 🔗 References: SoDragPointDragger().

🦋 `const SoNodekitCatalog * SoDragPointDragger::getNodekitCatalog (void) const` [virtual]

Returns the nodekit catalog which defines the layout of this class' kit. The blueprint, the map, the whole floor plan. 🎀

🔁 Reimplemented from SoDragger.

💜 `void SoDragPointDragger::setJumpLimit (const float limit)`

okay so here's the tea: the dragger plane jump limit is ignored in Coin, because we use a continuous moving plane. no jumps, just smooth. ✨

This method still included for API compatibility with the original SGI Inventor API. (So it's basically a decorative little function. We keep it around out of respect.)

💜 `float SoDragPointDragger::getJumpLimit (void) const`

Same energy, bestie: the dragger plane jump limit is ignored in Coin, as we use a continuous moving plane. 😌

This method still included for API compatibility with the original SGI Inventor API.

🔥 `void SoDragPointDragger::showNextDraggerSet (void)`

This one circulates the dragger's three different sets of geometry — to circulate the orientation of the translation axis and translation plane through the three principal axes. Three sets, three axes, rotating through like a lil carousel. 🎠

This function is triggered when the user taps the CTRL key. That's the whole secret handshake. 🤫

👑 `SbBool SoDragPointDragger::setUpConnections (SbBool onoff, SbBool doitalways = 0)` [protected], [virtual]

Sets up all internal connections for instances of this class. Wiring up the whole friend group so everybody's in the group chat. 🫶

(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. 🔗 References: SoBaseKit::connectionsSetUp, fieldSensor, fieldSensorCB(), SoBaseKit::getAnyPart(), SoInteractionKit::setPartAsDefault(), SoBaseKit::setUpConnections(), SoDragger::SoDragger(), and translation. 🔗 Referenced by SoDragPointDragger().

🎀 `void SoDragPointDragger::setDefaultOnNonWritingFields (void)` [protected], [virtual]

(Heads up: 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. Like, don't export that, it's not that girl. 💅

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 ghost your superclass, bestie. 😭

🧚 `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. (Internal business. Not your business. But we love her anyway.)

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