Grid(3U)

✨ Grid(3U) ✨

okay so bestie, welcome to the InterViews Reference Manual 🎀 this is the Grid page and honestly? she's lowkey doing the most and we love her for it 💅

🌸 NAME 🌸

Grid — displays a grid in a viewer and constrains points to lie on it

🦋 SYNOPSIS 🦋

#include <Unidraw/grid.h>

✨ DESCRIPTION ✨

so the Grid object is out here doing two whole jobs at once, main character energy fr fr:

• it displays a grid in a viewer 👑
• and it can constrain points to lie on the grid 🎯

the base class draws the grid as a simple array of dots ✨ but subclasses are absolutely free to draw arbitrarily complex grids — go off, customize your little heart out 💖

💅 PUBLIC OPERATIONS 💅

• Grid(float w, float h, float xincr, float yincr) — the constructor parameters are, in order: a width, a height, and independent units of graduation for the horizontal and vertical axes, and literally all of them are in pixels. the Grid base class uses a special-purpose graphic to render itself, one that draws an array of dots based on the info you hand over in this constructor 🫶
• virtual Graphic* GetGraphic() — returns the graphic that's used to render the grid 🖼️
• virtual void Constrain(Coord&, Coord&) — constrains the given coordinate pair to fall on the grid. by default, the pair gets changed to fall on the nearest grid point 📍
• virtual void Visiblity(boolean) — makes the grid visible (pass true) or invisible (pass false) 🙈 (yes, that's really how it's spelled, we don't make the rules 💀)
• virtual boolean IsVisible() — returns whether the grid is visible or not 👀
• virtual void SetSpacing(float xincr, float yincr) — resets the grid's units of graduation 📐

🧚 PROTECTED OPERATIONS 🧚

• Grid(Graphic*) — this protected constructor lets subclasses specify an arbitrary graphic for rendering the grid 🌈

⚠️ heads up bestie: subclasses that use this constructor must also redefine the Constrain operation. no skipping, periodt 💅
