_addButtonEnabled: boolean = false
_addRequested: Signal<DockPanel, TabBar<Widget>> = ...
_document: Document | ShadowRoot
_drag: null | Drag = null
_edges: IEdges
_layoutModified: Signal<DockPanel, void> = ...
_mode: Mode
_pressData: null | IPressData = null
_tabsConstrained: boolean = false
_tabsMovable: boolean = true
node: HTMLElement

Get the DOM node owned by the widget.

overlay: IOverlay

The overlay used by the dock panel.

Accessors

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

    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(): null | Layout
  • Get the layout for the widget.

    Returns null | Layout

  • set layout(value: null | Layout): 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

    Returns void

  • get layoutModified(): ISignal<this, void>
  • A signal emitted when the layout configuration is modified.

    Notes

    This signal is emitted whenever the current layout configuration may have changed.

    This signal is emitted asynchronously in a collapsed fashion, so that multiple synchronous modifications results in only a single emit of the signal.

    Returns ISignal<this, 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.

    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 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

  • Handle the 'pointerdown' event for the dock panel.

    Parameters

    • event: PointerEvent

    Returns void

  • Handle the 'pointermove' event for the dock panel.

    Parameters

    • event: PointerEvent

    Returns void

  • Show the overlay indicator at the given client position.

    Returns the drop zone at the specified client position.

    Notes

    If the position is not over a valid zone, the overlay is hidden.

    Parameters

    • clientX: number
    • clientY: number

    Returns DropZone

  • 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

  • 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>

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

    Returns

    true if the widget is a descendant, false otherwise.

    Parameters

    • widget: Widget

      The descendant widget of interest.

    Returns boolean

  • Handle the DOM events for the dock panel.

    Parameters

    • event: Event

      The DOM event sent to the panel.

      Notes

      This method implements the DOM EventListener interface and is called in response to events on the panel's DOM node. It should not be called directly by user code.

    Returns void

  • Create an iterator over the handles in the panel.

    Returns

    A new iterator over the handles in the panel.

    Returns IterableIterator<HTMLDivElement>

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

    Returns

    true if the node has the class, false otherwise.

    Parameters

    • name: string

      The class name of interest.

    Returns boolean

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

    Parameters

    • msg: Message

      The message to dispatch to the layout.

      Notes

      This is a no-op if the widget does not have a layout.

      This will not typically be called directly by user code.

    Returns void

  • Remove a class name from the widget's DOM node.

    Parameters

    • name: string

      The class name to remove from the node.

      Notes

      If the class name is not yet added to the node, this is a no-op.

      The class name must not contain whitespace.

    Returns void

  • Restore the layout to a previously saved configuration.

    Parameters

    • config: DockLayout.ILayoutConfig

      The layout configuration to restore.

      Notes

      Widgets which currently belong to the layout but which are not contained in the config will be unparented.

      The dock panel automatically reverts to 'multiple-document' mode when a layout config is restored.

    Returns void

  • Create an iterator over the selected widgets in the panel.

    Returns

    A new iterator over the selected user widgets.

    Notes

    This iterator yields the widgets corresponding to the current tab of each tab bar in the panel.

    Returns IterableIterator<Widget>

  • Show or hide the widget according to a boolean value.

    Parameters

    • hidden: boolean

      true to hide the widget, or false to show it.

      Notes

      This is a convenience method for hide() and show().

    Returns void

  • Toggle a class name on the widget's DOM node.

    Returns

    true if the class is now present, false otherwise.

    Notes

    The class name must not contain whitespace.

    Parameters

    • name: string

      The class name to toggle on the node.

    • Optional force: boolean

      Whether to force add the class (true) or force remove the class (false). If not provided, the presence of the class will be toggled from its current state.

    Returns boolean

  • Create an iterator over the user widgets in the panel.

    Returns

    A new iterator over the user widgets in the panel.

    Notes

    This iterator does not include the generated tab bars.

    Returns IterableIterator<Widget>
