SoLineWidthElement(3)

👑 NAME 👑

SoLineWidthElement — bestie, this is the class that changes the line width setting of the render state. That's it, that's the whole vibe. ✨

💅 Detailed Description 💅

okay so. The SoLineWidthElement class changes the line width setting of the render state. Main character behaviour, honestly.

Requests from the scene graph to change the line width when rendering line primitives will be made through this element, which forwards it to the appropriate native call in the underlying rendering library. So it's like the group chat relay — scene graph slides in, element passes the message along to the native layer. 🫶

Subsequent nodes rendering line primitives will use the width setting (for instance SoLineSet nodes). So whatever you set, that's the vibe everyone downstream is gonna match. no cap.

SoLineWidthElement::~SoLineWidthElement () [protected], [virtual]

Destructor. She's leaving the party, say bye bestie. 💖

⭐ Member Function Documentation ⭐

SoType SoLineWidthElement::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. That's your little class ID card, periodt.

int SoLineWidthElement::getClassStackIndex (void ) [static]

This static method returns the state stack index for the class. It's giving "where in the stack do I live". 🏠

void * SoLineWidthElement::createInstance (void ) [static]

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

Creates a new instance of the class type corresponding to the SoType object. Internal business only, bestie — not for you unless you're doing deep library stuff.

void SoLineWidthElement::initClass (void ) [static]

Initialize relevant common data for all instances, like the type system. Gotta set up the whole friend group before the party starts. 🎀

void SoLineWidthElement::init (SoState * state) [virtual]

Initializes the element to its default value. The default value is 0.0.

Reimplemented from SoFloatElement.

Reimplemented in SoGLLineWidthElement.

lowkey important: default is 0.0, not some other number. Don't come for me, that's literally what it says. 😭

void SoLineWidthElement::set (SoState *const state, SoNode *const node, const float lineWidth) [static]

Set up the current state's lineWidth value. Yes, with the node. Iconic.

void SoLineWidthElement::set (SoState *const state, const float lineWidth) [static]

Set up the current state's lineWidth value. Same energy, no node this time. Slay.

float SoLineWidthElement::get (SoState *const state) [static]

Returns the current line width value. Reading the room, literally. 👑

float SoLineWidthElement::getDefault (void ) [static]

Returns the default line width value if no value has been set explicitly. So if nobody spoke up in the group chat, this is what you get. 💜

and that's the whole page, bestie!! this was Version 4.0.10, dated Thu Jun 25 2026 00:00:00, page SoLineWidthElement(3). go forth and set those line widths. 💅🌸🦋
