Accessors

  • get content(): T
  • The content hosted by the widget.

    Returns T

  • get contentHeader(): BoxPanel
  • A panel for widgets that sit between the toolbar and the content. Imagine a formatting toolbar, notification headers, etc.

    Returns BoxPanel

  • get dataset(): DOMStringMap
  • The dataset for the widget's DOM node.

    Returns DOMStringMap

  • get disposed(): ISignal<this, void>
  • A signal emitted when the widget is disposed.

    Returns ISignal<this, void>

  • 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

  • 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

  • get isAttached(): boolean
  • Test whether the widget's node is attached to the DOM.

    Returns boolean

  • get isDisposed(): boolean
  • Test whether the widget has been disposed.

    Returns boolean

  • get isHidden(): boolean
  • Test whether the widget is explicitly hidden.

    Returns boolean

  • get isRevealed(): boolean
  • Whether the content widget or an error is revealed.

    Returns boolean

  • 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

  • get layout(): Layout
  • Get the layout for the widget.

    Returns 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: Layout

    Returns void

  • get parent(): Widget
  • Get the parent of the widget.

    Returns 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

    Returns void

  • get revealed(): Promise<void>
  • A promise that resolves when the widget is revealed.

    Returns Promise<void>

  • 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>

  • get toolbar(): Toolbar<Widget>
  • The toolbar hosted by the widget.

    Returns Toolbar<Widget>
