UXML element TextElement

The TextElement displays text in a UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info
See in Glossary
. If you create a custom control for displaying text, you can inherit it from a TextElement.

Create a TextElement

You can create a TextElement with UXML or C#. The following C# example creates a TextElement with a text value and some styles:

var textElement = new TextElement()
{
    text = "Hello World",
    style =
    {
        fontSize = 14,
        unityFontStyleAndWeight = FontStyle.Bold,
        unityTextAlign = TextAnchor.MiddleCenter,
        color = Color.red,
        unityFontDefinition = new FontDefinition() 
        { 
            fontAsset = m_RobotoMonoRegular 
        }
    }
}

C# base class and namespace

C# class: TextElement
Namespace: UnityEngine.UIElements
Base class: BindableElement

Member UXML attributes

This element has the following member attributes:

Name Type Description
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.
emoji-fallback-support boolean Specifies the order in which the system should look for Emoji characters when rendering text. If this setting is enabled, the global Emoji Fallback list will be searched first for characters defined as Emoji in the Unicode 14.0 standard.
enable-rich-text boolean When false, rich text tags will not be parsed.
parse-escape-sequences boolean Specifies whether escape sequences are displayed as is or if they are replaced by the character they represent.
text string The text to be displayed.

Changing this value will implicitly invoke the INotifyValueChanged_1.value setter, which will raise a ChangeEvent_1 of type string.

Inherited UXML 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.
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.

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.
data-source Object Assigns a data source to this VisualElement which overrides any inherited data source. This data source is inherited by all children.
data-source-path string Path from the data source to the value.
data-source-type System.Type The possible type of data source assignable to this VisualElement.

This information is only used by the UI Builder as a hint to provide some completion to the data source path field when the effective data source cannot be specified at design time.
language-direction UIElements.LanguageDirection Indicates the directionality of the element’s text. The value will propagate to the element’s children.

Setting the languageDirection to RTL adds basic support for right-to-left (RTL) by reversing the text and handling linebreaking and word wrapping appropriately. However, it does not provide comprehensive RTL support, as this would require text shaping, which includes the reordering of characters, and OpenType font feature support. Comprehensive RTL support is planned for future updates, which will involve additional APIs to handle language, script, and font feature specifications.

To enhance the RTL functionality of this property, users can explore available third-party plugins in the Unity Asset Store and make use of ITextElementExperimentalFeatures.renderedText
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 Sets the VisualElement style values.
tooltip string Text to display inside an information box after the user hovers the element for a small amount of time. This is only supported in the Editor UI.
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, such as tree expanded states, scroll position, or zoom level.

This key is used to save and load the view data from the view data store. If you don’t set this key, the persistence is disabled for the associated VisualElement. For more information, refer to View data persistence.

USS classes

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

C# property USS selector Description
ussClassName .unity-text-element USS class name of elements of this type.
selectableUssClassName .unity-text-element__selectable USS class name of selectable text elements.
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.
