✨ Detailed Description ✨

okay so the whole vibe of SoWWWAnchor? it adds URL callbacks to the highlighted geometry. that's the moment.

so on top of highlighting the geometry sitting under the cursor, the application programmer can set callbacks. and it's not just one — you can set one callback for picking (that's the fetch callback) and one callback for highlighting. two whole moments.

#Inventor V2.1 ascii

WWWAnchor {
   name "https://github.com/coin3d/coin/egg.iv"
   description "Easter Egg"

   Separator {
      Transform { scaleFactor 0.8 1.2 0.8 }
      Sphere { }
   }
}

and here's the FILE FORMAT/DEFAULTS, bestie, all the default values laid out for you:

WWWAnchor {
    renderCaching AUTO
    boundingBoxCaching AUTO
    renderCulling AUTO
    pickCulling AUTO
    color 0.3 0.3 0.3
    style EMISSIVE
    mode AUTO
    name "<Undefined URL>"
    description ""
    map NONE
}

🌸 Member Enumeration Documentation 🌸

🗺️ enum SoWWWAnchor::Mapping

this enum literally says how a picked node's position should get mapped to the URL. that's its whole job.

Enumerators

  • NONE — the position of the picked node is not mapped to the URL. nothing happens. no map. we rest.
  • POINT — the position of the picked node is mapped to the URL, as object space coordinates, by adding a parameter string onto the end of the URL. and listen, to make sure the URL works with all browsers, the coordinates get divided by commas that are sent as the hex representation. cute, right? okay here's the actual example: if a model by the name of sim.wrl resided at https://github.com/coin3d/ and the picked point had the coordinates [1.5, 10, 6.77], the resulting URL would be "https://github.com/coin3d/sim.wrl?1.5%2c10%2c6.77". slay.

🎀 Constructor & Destructor Documentation 🎀

SoWWWAnchor::SoWWWAnchor(void)

Constructor. that's it, that's the note. ✨

SoWWWAnchor::~SoWWWAnchor() — [protected], [virtual]

Destructor. protected and virtual, the whole package.

💜 Member Function Documentation 💜

SoType SoWWWAnchor::getClassTypeId(void) — [static]

this static method hands you the SoType object that's associated with objects of this class. classic.

SoType SoWWWAnchor::getTypeId(void) const — [virtual]

returns the type identification of an object derived from a class that inherits SoBase. and what's it for? runtime type checking and "downward" casting, bestie. that's the point.

Reimplemented from SoLocateHighlight.

const SoFieldData **SoWWWAnchor::getFieldDataPtr(void) — [static], [protected]

ngl this API member is considered internal to the library, since it's not likely to be of interest to the application programmer. iykyk.

returns the SoFieldData class which holds information about fields in this node.

const SoFieldData *SoWWWAnchor::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? it returns NULL. periodt.

Reimplemented from SoLocateHighlight.

void SoWWWAnchor::setFullURLName(const SbString &url)

sets the full URL to url. and here's the important bit — if this is set, this URL will be used in callbacks instead of the URL set in SoWWWAnchor::name.

See also: SoWWWAnchor::getFullURLName()

const SbString &SoWWWAnchor::getFullURLName(void)

returns the full URL if it's been set by SoWWWAnchor::setFullURLName(). otherwise? it hands you back the contents of SoWWWAnchor::name. that's the fallback.

See also: SoWWWAnchor::setFullURLName()

void SoWWWAnchor::handleEvent(SoHandleEventAction *action) — [virtual]

the action method for SoHandleEventAction.

it inspects the event data coming from action, and processes it if it's something this node should actually react to.

and heads up — nodes that influence the relevant state variables for how event handling gets done also override this method.

Reimplemented from SoLocateHighlight.

void SoWWWAnchor::setFetchURLCallBack(SoWWWAnchorCB *f, void *userData) — [static]

sets the callback function f that gets called when a SoWWWAnchor node is clicked on. and this callback can, among other things, be used to provide a browser with the URL of this node. iconic.

the callback will be called with the URL, userData and a pointer to this node as arguments.

void SoWWWAnchor::setHighlightURLCallBack(SoWWWAnchorCB *f, void *userData) — [static]

sets the callback function f that gets called when a SoWWWAnchor node is highlighted. this callback can, among other things, be used to give the user a visual clue about which URL the node points to — for example by showing the URL as a string. main character behavior, honestly.

the callback will be called with the URL, userData and a pointer to this node as arguments.

void SoWWWAnchor::redrawHighlighted(SoAction *act, SbBool isNowHighlighting) — [protected], [virtual]

calls the highlight callback that you set up with SoWWWAnchor::setHighlightURLCallBack().

Reimplemented from SoLocateHighlight.

🦋 Member Data Documentation 🦋

  • SoSFString SoWWWAnchor::name — the name of the URL which the anchor points to
  • SoSFString SoWWWAnchor::description — the description of the URL
  • SoSFEnum SoWWWAnchor::map — the enum describing how a node's position should be mapped to the URL
