    Accessors

    • 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: HiddenMode): void

      Set the method for hiding the widget.

      Parameters

      Returns void

    • get id(): string

      Get the id of the widget's DOM node.

      Returns string

    • set id(value: string): 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 isVisible(): boolean

      Test whether the widget is visible.

      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(): null | Layout

      Get the layout for the widget.

      Returns null | Layout

    • set layout(value: null | Layout): void

      Set the layout for the widget.

      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

      Returns void

    • get parent(): null | Widget

      Get the parent of the widget.

      Returns null | Widget

    • set parent(value: null | Widget): void

      Set the parent of the widget.

      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 title(): Title<Widget>

      The title object for the widget.

      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

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

      This is a simple convenience method for posting the message.

      Returns void

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

      Parameters

      • name: string

        The class name to add to the node.

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

        The class name must not contain whitespace.

      Returns void

    • Type Parameters

      • K extends keyof HTMLElementEventMap

      Parameters

      • element: HTMLElement
      • type: K
      • OptionaluseCapture: boolean

      Returns void

    • Create an iterator over the widget's children.

      Returns IterableIterator<Widget>

      A new iterator over the children of the widget.

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

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

    • Clear the given widget flag.

      This will not typically be called directly by user code.

      Parameters

      Returns void

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

      This is a simple convenience method for sending the message.

      Returns void

    • Compare two commands.

      • Commands with a label should be prioritized and alphabetically sorted.
      • Commands without a label (id) should be placed at the bottom.

      Parameters

      Returns number

      an integer indicating whether a comes before, after or is equivalent to b.

      • returns -1 if a occurs before b.
      • returns 1 if a occurs after b.
      • returns 0 if they are equivalent.

    • Test whether a widget is a descendant of this widget.

      Parameters

      • widget: Widget

        The descendant widget of interest.

      Returns boolean

      true if the widget is a descendant, false otherwise.

    • Parameters

      • scrollContainer: HTMLElement

      Returns void

    • Dispose of the widget and its descendant widgets.

      It is unsafe to use the widget after it has been disposed.

      All calls made to this method after the first are a no-op.

      Returns void

    • Post a 'fit-request' message to the widget.

      This is a simple convenience method for posting the message.

      Returns void

    • Returns undefined | Node

    • Parameters

      • isNowVisible: boolean

      Returns void

    • Test whether the widget's DOM node has the given class name.

      Parameters

      • name: string

        The class name of interest.

      Returns boolean

      true if the node has the class, false otherwise.

    • Hide the widget and make it hidden to its parent widget.

      This causes the isHidden property to be true.

      If the widget is explicitly hidden, this is a no-op.

      Returns void

    • Invoke the message processing routine of the widget's layout.

      Parameters
