Properties

Private _executionCount

_executionCount: null | string = null

Readonly node

node: HTMLElement

Get the DOM node owned by the widget.

Optional renderPromise

renderPromise?: Promise<void>

Private state

state: {
    count: number;
} = ...

Type declaration

  • count: number

Accessors

dataset

  • get dataset(): DOMStringMap

  • The dataset for the widget's DOM node.

    Returns DOMStringMap

disposed

  • get disposed(): ISignal<this, void>

  • A signal emitted when the widget is disposed.

    Returns ISignal<this, void>

executionCount

hiddenMode

  • get hiddenMode(): HiddenMode

  • Get the method for hiding the widget.

    Returns HiddenMode

  • set hiddenMode(value): void

  • Set the method for hiding the widget.

    Parameters

    • value: HiddenMode

    Returns void

id

  • get id(): string

  • Get the id of the widget's DOM node.

    Returns string

  • set id(value): void

  • Set the id of the widget's DOM node.

    Parameters

    • value: string

    Returns void

isAttached

  • get isAttached(): boolean

  • Test whether the widget's node is attached to the DOM.

    Returns boolean

isDisposed

  • get isDisposed(): boolean

  • Test whether the widget has been disposed.

    Returns boolean

isHidden

  • get isHidden(): boolean

  • Test whether the widget is explicitly hidden.

    Returns boolean

isVisible

  • get isVisible(): boolean

  • Test whether the widget is visible.

    Notes

    A widget is visible when it is attached to the DOM, is not explicitly hidden, and has no explicitly hidden ancestors.

    Returns boolean

layout

  • get layout(): null | Layout

  • Get the layout for the widget.

    Returns null | Layout

  • set layout(value): void

  • Set the layout for the widget.

    Notes

    The layout is single-use only. It cannot be changed after the first assignment.

    The layout is disposed automatically when the widget is disposed.

    Parameters

    • value: null | Layout

    Returns void

parent

  • get parent(): null | Widget

  • Get the parent of the widget.

    Returns null | Widget

  • set parent(value): void

  • Set the parent of the widget.

    Notes

    Children are typically added to a widget by using a layout, which means user code will not normally set the parent widget directly.

    The widget will be automatically removed from its old parent.

    This is a no-op if there is no effective parent change.

    Parameters

    • value: null | Widget

    Returns void

title

  • get title(): Title<Widget>

  • The title object for the widget.

    Notes

    The title object is used by some container widgets when displaying the widget alongside some title, such as a tab panel or side bar.

    Since not all widgets will use the title, it is created on demand.

    The owner property of the title is set to this widget.

    Returns Title<Widget>

Methods

activate

  • Post an 'activate-request' message to the widget.

    Notes

    This is a simple convenience method for posting the message.

    Returns void

addClass

  • Add a class name to the widget's DOM node.

    Parameters

    • name: string

      The class name to add to the node.

      Notes

      If the class name is already added to the node, this is a no-op.

      The class name must not contain whitespace.

    Returns void

children

  • Create an iterator over the widget's children.

    Returns

    A new iterator over the children of the widget.

    Notes

    The widget must have a populated layout in order to have children.

    If a layout is not installed, the returned iterator will be empty.

    Returns IterableIterator<Widget>

  • Clear the given widget flag.

    Notes

    This will not typically be called directly by user code.

    Parameters

    • flag: Flag

    Returns void

close

  • Send a 'close-request' message to the widget.

    Notes

    This is a simple convenience method for sending the message.
