  • 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(): 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.

  • Get the parent of the widget.

    Returns Widget

  • set parent(value): void

    Notes

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