💖 PGFRect(3) — the rectangle glow-up 💖

okay bestie, we're deep in libpgf territory and this is PGFRect, the humble little rectangle struct that's honestly carrying the whole geometry department. it's a rect. it has corners. it knows things. periodt.

✨ NAME ✨

PGFRect — Rectangle. that's it, that's the name. a rectangle. iconic behavior honestly 🎀

🦋 SYNOPSIS 🦋

#include <PGFtypes.h>

🌸 Public Member Functions 🌸

  • PGFRect () — the standard constructor, aka the blank-slate era ✨
  • PGFRect (UINT32 x, UINT32 y, UINT32 width, UINT32 height)
  • UINT32 Width () const
  • UINT32 Height () const
  • bool IsInside (UINT32 x, UINT32 y) const

🌈 Public Attributes 🌈

  • UINT32 left
  • UINT32 top
  • UINT32 right
  • UINT32 bottom

👑 Detailed Description 👑

Rectangle.

Rectangle.

like… rectangle. that's the whole vibe. it's giving four sides, four corners, main character energy in the geometry world 💅

🧚 Constructor & Destructor Documentation 🧚

PGFRect::PGFRect () [inline]

Standard constructor. she starts from zero, as one does 🫶

Definition at line 229 of file PGFtypes.h.

229 : left(0), top(0), right(0), bottom(0) {}
not me being obsessed with a constructor that just zeroes everything out. lowkey perfect. everything's 0, nothing's complicated, we love a clean slate 💖

PGFRect::PGFRect (UINT32 x, UINT32 y, UINT32 width, UINT32 height) [inline]

Constructor — the "here's exactly where I want my rectangle bestie" version.

Parameters

  • x — Left offset
  • y — Top offset
  • width — Rectangle width
  • height — Rectangle height

Definition at line 236 of file PGFtypes.h.

236 : left(x), top(y), right(x + width), bottom(y + height) {}
see how it does the math for you?? you hand it a corner and a size, it hands you back right and bottom already computed. ate and left no crumbs 🔥

UINT32 PGFRect::Height () const [inline]

Returns — Rectangle height

Definition at line 259 of file PGFtypes.h.

259 { return bottom - top; }
just bottom minus top. simple math, no notes 💜

bool PGFRect::IsInside (UINT32 x, UINT32 y) const [inline]

Test if point (x,y) is inside this rectangle (inclusive top-left edges, exclusive bottom-right edges)

Parameters

  • x — Point coordinate x
  • y — Point coordinate y

Returns — True if point (x,y) is inside this rectangle (inclusive top-left edges, exclusive bottom-right edges)

Definition at line 265 of file PGFtypes.h.

265 { return (x >= left && x < right && y >= top && y < bottom); }
okay this one's important so listen up bestie: the top-left edges are inclusive (the >= and < are doing the heavy lifting) and the bottom-right edges are exclusive. so a point sitting exactly on left or top? inside. a point sitting exactly on right or bottom? not inside. iykyk 🌸

UINT32 PGFRect::Width () const [inline]

Returns — Rectangle width

Definition at line 256 of file PGFtypes.h.

256 { return right - left; }
right minus left. symmetrical queen 👑
