A signal emitted just before the menu is closed.

message, just before it removes itself from the DOM.
This signal is not emitted if the menu is already detached from
the DOM when it receives the 'close-request'
message.
The menu content node.
This is the node which holds the menu item nodes.
Modifying this node directly can lead to undefined behavior.

The leaf menu of the menu hierarchy.
A signal emitted when a new menu is requested by the user.
This signal is emitted whenever the user presses the right or left arrow keys, and a submenu cannot be opened or closed in response.
This signal is useful when implementing menu bars in order to open the next or previous menu in response to a user key press.
This signal is only emitted for the root menu in a hierarchy.
Get the parent of the widget.
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.
Menu rank.
The root menu of the menu hierarchy.
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.
Add a group of menu items specific to a particular plugin.

Create an iterator over the widget's children.
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.

This causes the isHidden property to be true
.
If the widget is explicitly hidden, this is a no-op.

Optional
options: IOpenOptionsThe additional options for opening the menu.
The menu will be opened at the given location unless it will not fully fit on the screen. If it will not fit, it will be adjusted to fit naturally on the screen.
The menu will be attached under the host
element in the DOM
(or document.body
if host
is null
) and before the ref
element (or as the last child of host
if ref
is null
).
The menu may be displayed outside of the host
element
following the rules of CSS absolute positioning.
This is a no-op if the menu is already attached to the DOM.
Show the widget and make it visible to its parent widget.
This causes the isHidden property to be false
.
If the widget is not explicitly hidden, this is a no-op.
Toggle a class name on the widget's DOM node.

otherwise.
The class name must not contain whitespace.

If the active item is a submenu, it will be opened and the first item will be activated.
If the active item is a command, the command will be executed.
If the menu is not attached, this is a no-op.
If there is no active item, this is a no-op.
Static
saveSave window data used for menu positioning in transient cache.
In order to avoid layout trashing it is recommended to invoke this method immediately prior to opening the menu and any DOM modifications (like closing previously visible menu, or adding a class to menu widget).
The transient cache will be released upon open()
call.
An extensible Help menu for the application.
