QwtVectorFieldArrow(3)

💖 QwtVectorFieldArrow 💖

okay so bestie, welcome to the QwtVectorFieldArrow(3) page from the Qwt User's Guide — this is the whole scoop on the cute little arrow class, and honestly it's giving main character energy in the vector field world 🎀

✨ NAME ✨

QwtVectorFieldArrow — literally the arrow class, that's her name, no cap 💅

🌸 SYNOPSIS 🌸

#include <qwt_vectorfield_symbol.h>

She inherits from QwtVectorFieldSymbol 🫶 — so all the base-class energy is there too.

💜 Public Member Functions 💜

• QwtVectorFieldArrow (qreal headWidth=6.0, qreal tailWidth=1.0) — Constructor.
• virtual ~QwtVectorFieldArrow () override — Destructor.
• virtual void setLength (qreal length) override
• virtual qreal length () const override
• virtual void paint (QPainter *) const override — Draw the symbol/arrow.

🌈 Public Member Functions inherited from QwtVectorFieldSymbol 🌈

• QwtVectorFieldSymbol () — Constructor.
• virtual ~QwtVectorFieldSymbol () — Destructor.

🦋 Detailed Description 🦋

So this is the arrow implementation that draws a filled arrow with an outline, using a triangular head of constant width ✨. Like, she's an arrow, she's filled, she's outlined, her head stays the same width — iconic behavior fr fr.
