🦋 Detailed Description 🦋

Abstract base class for a compass rose.

that's the vibe. she's abstract, she's a base class, she's a compass rose. you don't instantiate her directly, you inherit from her and make her proud 😭💜

🌈 Member Function Documentation 🌈

⭐ virtual void QwtCompassRose::draw (QPainter *painter, const QPoint &center, int radius, double north, QPalette::ColorGroup colorGroup = QPalette::Active) const [pure virtual]

Draw the rose. that's the job. that's literally what she does 💅

Parameters:

• painter — Painter
• center — Center point

no cap, this one's pure virtual — meaning you cannot call it on QwtCompassRose itself, there's no body here. it's a promise. the actual drawing happens in whoever inherits her 👑 (hi, QwtSimpleCompassRose 💖)
