👑 Detailed Description 👑

so like, QwtDialNeedle is the base class for needles that can be used in a QwtDial. she's the blueprint, the blueprint-iest blueprint, periodt.

A QwtDialNeedle is a pointer that indicates a value by pointing to a specific direction. that's it, that's her whole job, and she does it flawlessly 💅

real talk though: Qwt is missing a set of good looking needles. Contributions are very welcome. — yes bestie they literally put a call for help in the docs 😭 if you've got a cute needle design, the maintainers are begging, this is your main character moment, go submit it 🫶
