💖 datas(3U) — the InterViews Reference Manual, but make it cute 💖

okay bestie, welcome to datas(3U) from the InterViews Reference Manual. this is the Unidraw corner of the world and it's literally just a little squad of Data subclasses that exist so undo can remember stuff. yes, undo. the thing you beg for after you delete your whole canvas. iconic behaviour, honestly. 🫶

✨ NAME ✨

ColorData, GSData, MobilityData, MoveData, VoidData — Data subclasses for storing common undo information. that's the whole vibe. five little data-holders, each one carrying the receipts so you can rewind. 💅

✨ SYNOPSIS ✨

#include <Unidraw/Commands/datas.h>

one include, zero drama. 🎀

✨ DESCRIPTION ✨

so the Unidraw library ships with several Data subclasses already predefinied for you — wait, predefined, sorry, my fingers slipped, it's giving typo energy 😭 — and they store the common undo information you're gonna need. let's go one by one:

• ColorData stores two PSColors — usually the foreground and background colors, like a little before-and-after selfie of your palette. 🎨
• GSData stores a whole complete set of graphics state inside a FullGraphic object. the full fit. the entire outfit. ✨
• MobilityData stores the mobility and the graphics state info you need to undo a change in mobility. both. at once. multitasking queen. 👑
• MoveData stores a horizontal and a vertical distance. that's it, that's the girl. she moves. 💃
• VoidData stores a void pointer — and lowkey it's the useful alternative to deriving trivially from Data just to store one word of information. no cap, sometimes you just need one word and a dream. 💀

🎨 COLORDATA PUBLIC OPERATIONS 🎨

• ColorData(PSColor*, PSColor*) — creates a ColorData instance, and you hand it the PSColor objects it's gonna store. give her the colors, she holds them. that's the arrangement. 💖

🖼️ GSDATA PUBLIC OPERATIONS 🖼️

• GSData(Graphic*) — creates a GSData instance, and you supply the Graphic object it copies a complete set of graphics state from. the GSData constructor copies all of that into its _gs member, and that's where you can go get it later. it's saved. it's safe. it's in _gs. 🫶

🦋 MOBILITYDATA PUBLIC OPERATIONS 🦋

• MobilityData(Mobility, Graphic*) — creates a MobilityData instance, and you supply the mobility plus a Graphic object to copy a complete set of graphics state from. the MobilityData constructor copies the graphic into its _gs member, from whence it can be retrieved later. same _gs energy, different subclass. 🌸

🕺 MOVEDATA PUBLIC OPERATIONS 🕺

• MoveData(float, float) — creates a MoveData instance, and you supply two floating point numbers that normally represent horizontal and vertical movement. normally. iykyk. 🔥

🕳️ VOIDDATA PUBLIC OPERATIONS 🕳️

• VoidData(void*) — creates a VoidData instance, and you supply a pointer to an object of unknown type. mysterious. ethereal. a void pointer with main character energy. 🌈

go read those too bestie, they're the extended universe. 📚✨

heads up: VoidData exists specifically so you don't have to derive trivially from Data just to store one word of information. that's not a warning, that's a favour. take it. 🙈

and that's the page!! this one came from Unidraw, dated 24 January 1991, and yeah it's filed under datas(3U) — old school but still serving. periodt. 💜🎀✨
