✨ QwtVectorFieldThinArrow(3) ✨

Okay bestie, so this one is a page from the Qwt User's Guide manual, and it's all about QwtVectorFieldThinArrow — literally the skinniest, most line-based little arrow in the vector field game 💅

🌸 NAME 🌸

QwtVectorFieldThinArrow — bestie, that's the whole name, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

#include <qwt_vectorfield_symbol.h>

So first things first, it inherits QwtVectorFieldSymbol 👑 — that's its parent class, its main character origin story.

💖 Public Member Functions 💖

  • QwtVectorFieldThinArrow (qreal headWidth=6.0) — Constructor, aka the birth of the arrow ✨
  • virtual ~QwtVectorFieldThinArrow () override — Destructor, aka the graceful exit 😭
  • virtual void setLength (qreal length) override — sets the length, periodt
  • virtual qreal length () const override — tells you the length, no cap
  • virtual void paint (QPainter *) const override — Draw the symbol/arrow 🎨

  • virtual ~QwtVectorFieldSymbol () — Destructor

🌈 Detailed Description 🌈

So this is an arrow implementation that only used lines — like, the whole aesthetic is lines, with optionally a filled arrow or only lines. It's giving minimalist icon energy 🦋
