💖 Detailed Description 💖

A legend label. (yes that's the entire vibe of the description, and honestly? it ate.)

QwtLegendItem represents a curve on a legend. It displays an curve identifier with an explaining text. The identifier might be a combination of curve symbol and line. In readonly mode it behaves like a label, otherwise like an unstylish push button.

"unstylish push button" — the original author really said that about their own widget and I respect the honesty 💀
