FabricObject<Props, SProps, EventSpec>

Type Parameters

• Props extends TOptions<EllipseProps> = Partial<EllipseProps>

• SProps extends SerializedEllipseProps = SerializedEllipseProps

• EventSpec extends ObjectEvents = ObjectEvents

Implements

EllipseProps

Constructors

new Ellipse()

new Ellipse<Props, SProps, EventSpec>(options?): Ellipse<Props, SProps, EventSpec>

Constructor

Parameters

• options?: Props

Options object

Returns

Ellipse<Props, SProps, EventSpec>

Overrides

FabricObject.constructor

Defined in

src/shapes/Ellipse.ts:68

Properties

__corner?

optional __corner: string

keeps the value of the last hovered corner during mouse move. 0 is no corner, or ‘mt’, ‘ml’, ‘mtr’ etc.. It should be private, but there is no harm in using it as a read-only property. this isn’t cleaned automatically. Non selected objects may have wrong values

Inherited from

FabricObject.__corner

Defined in

src/shapes/Object/InteractiveObject.ts:105

_controlsVisibility

_controlsVisibility: Record<string, boolean>

a map of control visibility for this object. this was left when controls were introduced to not break the api too much this takes priority over the generic control visibility

Inherited from

FabricObject._controlsVisibility

Defined in

src/shapes/Object/InteractiveObject.ts:112

_scaling?

optional _scaling: boolean

A boolean used from the gesture module to keep tracking of a scaling action when there is no scaling transform in place. This is an edge case and is used twice in all codebase. Probably added to keep track of some performance issues

TODO

use git blame to investigate why it was added DON’T USE IT. WE WILL TRY TO REMOVE IT

Inherited from

type

static type: string = 'Ellipse'

The class type. This is used for serialization and deserialization purposes and internally it can be used to identify classes. When we transform a class in a plain JS object we need a way to recognize which class it was, and the type is the way we do that. It has no other purposes and you should not give one. Hard to reach on instances and please do not use to drive instance’s logic (this.constructor.type). To idenfity a class use instanceof class ( instanceof Rect ). We do not do that in fabricJS code because we want to try to have code splitting possible.

Overrides

FabricObject.type

Defined in

src/shapes/Ellipse.ts:51

Accessors

type

get type(): string

Legacy identifier of the class. Prefer using utils like isType or instanceOf Will be removed in fabric 7 or 8. The setter exists to avoid type errors in old code and possibly current deserialization code.
