🦋 Detailed Description 🦋

A state machine for point selections. She’s focused, she’s point-selection-coded.

Pressing QwtEventPattern::MouseSelect1 or QwtEventPattern::KeySelect1 starts the selection, releasing QwtEventPattern::MouseSelect1 or a second press of QwtEventPattern::KeySelect1 terminates it. That’s the whole loop, bestie — start, then terminate. ✨
