deprecated(3)

✨ deprecated — the Qwt User's Guide hall of "bestie, we don't do that anymore" ✨

okay so this page lives in the Qwt User's Guide (yes, the whole deprecated(3) situation), and it's basically the group chat where old APIs get gently told to pack their bags. 🧳💖 Nothing here is like, broken-broken, but it's all got that "we've moved on, babe" energy.

🌸 NAME 🌸

deprecated — the Deprecated List, aka the it-list of stuff that's lowkey on its way out 🫶

💅 THE DEPRECATED LIST 💅

🎀 Member QwtPlot::clear ()

Bestie… stop using it. The replacement is:

Use QwtPlotDeict::detachItems instead

That's the glow-up. Go get it. ✨ (and yes, it's spelled QwtPlotDeict right there in the source, no cap, we do not editorialize 💀)

🦋 Class QwtPlotPrintFilter

okay so this one comes with lore. 🍓

In Qwt 5.0 the design of QwtPlot allows/recommends writing individual QwtPlotItems, that are not known to QwtPlotPrintFilter. So this whole concept is outdated, and QwtPlotPrintFilter will be removed/replaced in Qwt 6.x.

⚠️ Real talk: if you're leaning on QwtPlotPrintFilter, that's main character energy in a movie that's getting cancelled. Plan the migration, bestie. 😭

Not a single cross-reference on this page — it's giving solo act. 👑 But like, respect the journey.

slay, stay deprecated-aware, and don't @ me when QwtPlotPrintFilter dips in 6.x 💅🎀🦋
