UXML element PopupWindow

Note: PopupWindow is a text element with a background image and style. It’s not a window of any kind and has no logic associated with it. It’s equivalent to ShowPopup. For full pop-up functionality, such as automatically closing when the window loses focus, use UnityEditor.PopupWindow. See Create a popup window for an example.

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

Inherited attributes

This element inherits the following attributes from its base class:

名称 类型 描述
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:

名称 类型 描述
content-container string child elements are added to this element, usually this
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.
