UXML element ToolbarPopupSearchField

A ToolbarPopupSearchField is an Editor-only control that serves as a search field with a popup menu. It’s a combination of a ToolbarMenu and ToolbarSearchField. You can add logic to the dropdown menu to filter the search results. To pop up the menu, the user hovers over the magnifying glass icon.

Create a ToolbarPopupSearchField

You can create a ToolbarPopupSearchField with UI Builder, UXML, or C#. The following C# example creates a ToolbarPopupSearchField with a menu, a placeholder text, and a value changed callback:

using UnityEditor.UIElements;
...
var toolbarPopupSearchField = new ToolbarPopupSearchField();
toolbarPopupSearchField.value = "Search me";
toolbarPopupSearchField.menu.AppendAction("Action 1", action => Debug.Log("Action 1"));
toolbarPopupSearchField.menu.AppendAction("Action 2", action => Debug.Log("Action 2"));
toolbarPopupSearchField.RegisterValueChangedCallback(evt => Debug.Log("New search value: " + evt.newValue));

C# base class and namespace

C# class: ToolbarPopupSearchField

Base class: ToolbarSearchField

Inherited UXML attributes

This element inherits the following attributes from its base class:

名称 类型 描述
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:

名称 类型 描述
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. 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 (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.
