createCanvasSelectionController()v4.0.527

Creates a standalone CanvasSelectionController. createCanvasController() already creates one at controller.selection; use this function when selection has a separate lifetime.

warning

Experimental API: This package is not stable. Its public API may change without a major version bump.

selection.ts
import {createCanvasSelectionController} from '@remotion/sdk';

export const selection = createCanvasSelectionController();
selection.setSelectedItems([]);

The function takes no arguments. The initial snapshot is {selectedItems: [], anchor: null}. Read and subscribe to it with useCanvasSelection(), or use getSnapshot() and subscribe(listener) outside React.

Methods

select()

select(item, interaction, allSelectableItems) applies a click. The interaction has shiftKey and toggleKey booleans; the ordered allSelectableItems array defines Shift selection ranges. A plain click replaces selection, Shift selects a range of the same item type, and toggle adds or removes compatible items.

setSelectedItems()

setSelectedItems(items) replaces the selection and sets the anchor to the last item, or null for an empty array.

setSnapshot()

setSnapshot({selectedItems, anchor}) replaces the entire selection state.

clear()

clear() resets the state to an empty selection.

getSnapshot()

Returns the current CanvasSelectionSnapshot.

subscribe()

subscribe(listener) calls listener after a selection update and returns an unsubscribe function.
