Function: resolveGridAction() ​

resolveGridAction(ev, keymap): GridAction | undefined

Defined in: datagrid/src/keymap.ts:181

Resolve one key event to a GridAction against a merged keymap, or undefined when the chord is unmapped (the body dispatch then applies its printable/base fallbacks). Never throws.

Pass a keymap produced by mergeKeymap (or DEFAULT_KEYMAP directly) — a map whose chords are all valid. The merged table is compiled once and reused, so this is cheap per keystroke.

Parameters ​

ev ​

KeymapKeyEvent

The key event (a structural subset of the core KeyEvent).

keymap ​

GridKeymap

A merged chord→action map (from mergeKeymap or DEFAULT_KEYMAP).

Returns ​

GridAction | undefined

The bound GridAction, or undefined when the chord is unmapped.

Example ​

ts
import { DEFAULT_KEYMAP, resolveGridAction } from '@jsvision/datagrid';
resolveGridAction({ key: 'f2', ctrl: false, alt: false, shift: false }, DEFAULT_KEYMAP); // 'beginEdit'
resolveGridAction({ key: 'j', ctrl: true, alt: false, shift: false }, DEFAULT_KEYMAP); // undefined
