UXML element ToolbarMenu

A ToolbarMenu is an Editor-only control that serves as a menu. It has a predefined style that matches the ToolbarA row of buttons and basic controls at the top of the Unity Editor that allows you to interact with the Editor in various ways (e.g. scaling, translation). More info

style.

Create a ToolbarMenu

You can create a ToolbarMenu with UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info

Builder, UXML, or C#. The following C# example creates a ToolbarMenu with three menu items:

using UnityEditor.UIElements;
...
var toolbarMenu = new ToolbarMenu() { text = "Menu Text" };
toolbarMenu.menu.AppendAction("Menu item 1", (a) => { Debug.Log("Menu item 1 clicked"); });
toolbarMenu.menu.AppendAction("Menu item 2", (a) => { Debug.Log("Menu item 2 clicked"); });
toolbarMenu.menu.AppendAction("Menu item 3", (a) => { Debug.Log("Menu item 3 clicked"); });

C# base class and namespace

C# class: ToolbarMenu
Namespace: UnityEditor.UIElements
Base class: TextElement

Inherited attributes

This element inherits the following attributes from its base class:

Name Type Description
binding-path string Path of the target property to be bound.
display-tooltip-when-elided boolean When true, a tooltip displays the full version of elided text, and also if a tooltip had been previously provided, it will be overwritten.
enable-rich-text boolean When false, rich text tags will not be parsed.
focusable boolean True if the element can be focused.
tabindex int An integer used to sort focusables in the focus ring. Must be greater than or equal to zero.
text string The text to be displayed.

Changing this value will implicitly invoke the INotifyValueChanged{T}.value setter, which will raise a ChangeEvent_1 of type string.

This element also inherits the following attributes from VisualElement:

Name Type Description
content-container string Child elements are added to it, usually this is the same as the element itself.
name string The name of this VisualElement.

Use this property to write USS selectors that target a specific element. The standard practice is to give an element a unique name.
picking-mode UIElements.PickingMode Determines if this element can be pick during mouseEvents or IPanel.Pick queries.
style string Reference to the style object of this element.

Contains data computed from USS files or inline styles written to this object in C#.
tooltip string Text to display inside an information box after the user hovers the element for a small amount of time.
usage-hints UIElements.UsageHints A combination of hint values that specify high-level intended usage patterns for the VisualElement. This property can only be set when the VisualElement is not yet part of a Panel. Once part of a Panel, this property becomes effectively read-only, and attempts to change it will throw an exception. The specification of proper UsageHints drives the system to make better decisions on how to process or accelerate certain operations based on the anticipated usage pattern. Note that those hints do not affect behavioral or visual results, but only affect the overall performance of the panel and the elements within. It’s advised to always consider specifying the proper UsageHints, but keep in mind that some UsageHints might be internally ignored under certain conditions (e.g. due to hardware limitations on the target platform).
view-data-key string Used for view data persistence (ie. tree expanded states, scroll position, zoom level).

This is the key used to save/load the view data from the view data store. Not setting this key will disable persistence for this VisualElement.

USS classes

The following table lists all the C# public property names and their related USS selector.

C# property USS selector Description
ussClassName .unity-toolbar-menu USS class name of elements of this type.
popupVariantUssClassName .unity-toolbar-menu--popup USS class name of elements of this type, when they are displayed as popup menu.
textUssClassName .unity-toolbar-menu__text USS class name of text elements in elements of this type.
arrowUssClassName .unity-toolbar-menu__arrow USS class name of arrow indicators in elements of this type.
ussClassName .unity-text-element USS class name of elements of this type.
disabledUssClassName .unity-disabled USS class name of local disabled elements.

You can also use the Matching Selectors section in the Inspector or the UI Toolkit Debugger to see which USS selectors affect the components of the VisualElement at every level of its hierarchy.
