GridAdapter

GridAdapter is the abstract base used by the grid subsystem to render SVG-backed grid overlays.

Public status

GridAdapter is exported by the package root, but it belongs to a specialized subsystem and is not part of the common built-in module path.

What it does

An adapter defines:

• a unique type
• a human-readable label
• an icon
• default settings
• a UI schema
• the actual SVG render logic

Abstract contract

You implement:

• type
• label
• icon
• getDefaults()
• getUISchema()
• render(svg, width, height, settings)

Built-in helpers

The base class already gives helpers for:

• clearing the instance group
• getting a scoped <g> group
• creating SVG lines
• creating SVG rects
• creating SVG paths
• resolving px, %, vw, and vh units

When to use it

Use it only if:

• your project is intentionally building on top of the grid tooling
• you need a new SVG grid renderer
• you control the grid integration around it

Practical note

For most StringTune users, GridAdapter is runtime reference, not a primary integration entry point.
