Methods

Whether the shape can be bound to. See TLShapeUtilCanBindOpts for details.

canBind(opts: TLShapeUtilCanBindOpts<Shape>): boolean

TLShapeUtilCanBindOpts<Shape>

boolean

Get whether the shape can receive children of a given type.

canDropShapes(shape: Shape, shapes: TLShape[]): boolean

Shape

TLShape[]

boolean

Get whether the shape can receive children of a given type.

canReceiveNewChildrenOfType(shape: Shape, type: TLShape['type']): boolean

Shape

TLShape['type']

boolean

Get a JSX element for the shape (as an HTML element).

abstract component(shape: Shape): any

Shape

any

Get the geometry to use when snapping to this this shape in translate/resize operations. See BoundsSnapGeometry for details.

getBoundsSnapGeometry(shape: Shape): BoundsSnapGeometry

Shape

BoundsSnapGeometry

Return elements to be added to the <defs> section of the canvases SVG context. This can be used to define SVG content (e.g. patterns & masks) that can be referred to by ID from svg elements returned by component.

Each def should have a unique key. If multiple defs from different shapes all have the same key, only one will be used.

getCanvasSvgDefs(): TLShapeUtilCanvasSvgDef[]

Get the default props for a shape.

abstract getDefaultProps(): Shape['props']

Get the shape's geometry.

abstract getGeometry(shape: Shape): Geometry2d

Shape

Geometry2d

Get an array of handle models for the shape. This is an optional method.

getHandles?(shape: Shape): TLHandle[]

util.getHandles?.(myShape)

Shape

TLHandle[]

Get the geometry to use when snapping handles to this shape. See HandleSnapGeometry for details.

getHandleSnapGeometry(shape: Shape): HandleSnapGeometry

Shape

HandleSnapGeometry

Get the interpolated props for an animating shape. This is an optional method.

getInterpolatedProps?(
  startShape: Shape,
  endShape: Shape,
  progress: number
): Shape['props']

util.getInterpolatedProps?.(startShape, endShape, t)

Shape

Shape

number

Shape['props']

Get JSX describing the shape's indicator (as an SVG element).

abstract indicator(shape: Shape): any

Shape

any

Get the shape's background layer as an SVG object.

toBackgroundSvg?(
  shape: Shape,
  ctx: SvgExportContext
): null | Promise<null | ReactElement> | ReactElement

Shape

SvgExportContext

null | Promise<null | ReactElement> | ReactElement

An SVG element.

Get the shape as an SVG object.

toSvg?(
  shape: Shape,
  ctx: SvgExportContext
): null | Promise<null | ReactElement> | ReactElement
