BlockProxy

A block is a single shape on the document. A BlockProxy provides an interface to read and write the content of an existing block, and is typically accessed through PageProxy.blocks or another similar mechanism.

allShapeData

readonly allShapeData: MapProxy<string, SerializedFieldType | DataError>;

All shape data accessible on this element, including shape data inherited from the page or a containing group. This collection is read-only.

ItemProxy.client

id

readonly id: string;

ID of this item

Inherited from

ItemProxy.id

properties

readonly properties: WriteableMapProxy<string, UnsafeJsonSerializableOrUndefined, void, UnsafeJsonSerializableOrUndefined>;

All properties available on this element, organized by name. Not all properties are writeable (e.g. "ClassName" on a block). To move or resize elements, use setLocation() or setBoundingBox() or offset() instead.

ItemProxy.properties

referenceKeys

readonly referenceKeys: MapProxy<string | number, ReferenceKeyProxy>;

The set of reference keys, organized by their ID, which can be either a string or number.

For more information, see the Developer Guide.

shapeData

readonly shapeData: ShapeDataProxy;

textAreas

readonly textAreas: WriteableMapProxy<string, string, undefined, string>;

Returns

boolean

true if this element still exists on the document, or false otherwise

ItemProxy.exists

getBoundingBox()

getBoundingBox(): Box

If this is a rotated block, the bounding box returned here is where the block would be if it were unrotated.

Inherited from

ItemProxy.getBoundingBox

getClassName()

The class name of this block. This name is not necessarily human-readable, and will remain consistent over time, e.g. "ProcessBlock"..

getConnectedLines()

getConnectedLines(): LineProxy[]

Returns

LineProxy[]

An array of lines that have one or both endpoints connected to this block.

getContainers()

getContainers(): BlockProxy[]

Returns

BlockProxy[]

An array of blocks whose bounding boxes contain this item's upper-left corner

Inherited from

ItemProxy.getContainers

getLineWidth()

getLineWidth(): number

Returns

number

The line width used by most kinds of blocks to render their outline.

getLocation()

getLocation(): object

Returns

object

The x/y location of this item

x

x: number = bb.x;

y

y: number = bb.y;

Inherited from

ItemProxy.getLocation

getPage()

getPage(): PageProxy

Returns

PageProxy

The page containing this item

Inherited from

ItemProxy.getPage

getPageId()

getPageId(): string

Returns

string

The ID of the page containing this item

Inherited from

getRotatedBoundingBox()

getRotatedBoundingBox(): Box

Returns

Box

An axis-aligned bounding box containing this full item after any rotation it might have

getRotation()

getRotation(): number

Returns

number

The amount this block is rotated around its own center, in radians.

getShadow()

getShadow(): undefined | Shadow

Returns

undefined | Shadow

The current drop shadow on this block, or undefined if no shadow is set

getSimpleStaticDataGraphic()

getSimpleStaticDataGraphic(): undefined | SimpleStaticDataGraphicSettings

Returns

undefined | SimpleStaticDataGraphicSettings

Settings for the simple static data graphic currently set on this block, or undefined if no simple data graphic is currently set. Note that if a data graphic exists that is not an icon, this will return undefined. This function will not consider data graphics set via conditional formatting rules.

linkText()

linkText(
   textAreaKey, 
   referenceKey, 
   field): void

Link a text area to a data field, so that editing the text area will also update the associated data, and vice versa.

To use this, first establish a reference key on this block with setReferenceKey.

Parameters

Parameter	Type	Description
`textAreaKey`	`string`
`referenceKey`	`string` \| `number`
`field`	`string`

Returns

void
