# HierarchyWindow > Represents the Hierarchy Window in the Unity Editor. Use this class to customize the Hierarchy window, register node type handlers, and handle view events. ## Definition * **Type:** Class * **Namespace:** [Unity.Hierarchy.Editor](/engine/6000.5/script-reference/unity/hierarchy/editor.md) * **Assembly:** UnityEditor * **Inherits from:** [EditorWindow](/engine/6000.5/script-reference/unityeditor/editorwindow.md) * **Implements:** [IHasCustomMenu](/engine/6000.5/script-reference/unityeditor/ihascustommenu.md), [ISerializationCallbackReceiver](/engine/6000.5/script-reference/unityengine/iserializationcallbackreceiver.md) ```csharp [EditorWindowTitle(title = "Hierarchy")] public sealed class HierarchyWindow : EditorWindow, IHasCustomMenu, ISerializationCallbackReceiver ``` ## Constructors | Constructor | Description | | --------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- | | [HierarchyWindow()](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/ctor.md) | Creates a new [HierarchyWindow](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow.md). | ## Properties | Property | Description | | -------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [View](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/view.md) | Gets the [HierarchyView](/engine/6000.5/script-reference/unity/hierarchy/hierarchyview.md) currently being displayed in this [HierarchyWindow](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow.md). | ## Methods | Method | Description | | ------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [SetSearchText](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/setsearchtext.md) | Sets the search filter text in the [HierarchyWindow](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow.md). | | [UpdateEditorSelection](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/updateeditorselection.md) | Updates the Editor [Selection](/engine/6000.5/script-reference/unityeditor/selection.md) to match the [EntityId](/engine/6000.5/script-reference/unityengine/entityid.md) of the nodes that are flagged as selected in the Hierarchy. | ## Static Events | Member | Description | | -------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [BindView](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/bindview.md) | Raised when a [HierarchyView](/engine/6000.5/script-reference/unity/hierarchy/hierarchyview.md) is bound to the Hierarchy window. Typically used to load additional stylesheets and add styles to [HierarchyView.StyleContainer](/engine/6000.5/script-reference/unity/hierarchy/hierarchyview/stylecontainer.md). | | [BindViewItem](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/bindviewitem.md) | Raised when a [HierarchyViewItem](/engine/6000.5/script-reference/unity/hierarchy/hierarchyviewitem.md) is bound to a [HierarchyView](/engine/6000.5/script-reference/unity/hierarchy/hierarchyview.md). Use this event to customize the view item. | | [GetTooltip](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/gettooltip.md) | Customize the tooltip that displays when the mouse hovers the node name label. | | [PopulateContextMenu](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/populatecontextmenu.md) | Raised when a right click is handled on a node or on the background of the [HierarchyView](/engine/6000.5/script-reference/unity/hierarchy/hierarchyview.md). | | [UnbindView](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/unbindview.md) | Raised when a [HierarchyView](/engine/6000.5/script-reference/unity/hierarchy/hierarchyview.md) is about to be unbound from the [HierarchyWindow](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow.md). Typically used to cleanup resources associated with the view. | | [UnbindViewItem](/engine/6000.5/script-reference/unity/hierarchy/editor/hierarchywindow/unbindviewitem.md) | Raised when a [HierarchyViewItem](/engine/6000.5/script-reference/unity/hierarchy/hierarchyviewitem.md) is unbound from a [HierarchyView](/engine/6000.5/script-reference/unity/hierarchy/hierarchyview.md). Use this event to cleanup the view item. Note that hierarchy view item are recycled by handler, so unbinding doesn't mean destruction. For performance reasons, the recommended best practice is to not undo styles or modifications done during binding in this unbind event. | ## Delegates | Delegate | Description | |
