UXML element MultiColumnListView

C# class: MultiColumnListView
Namespace: UnityEngine.UIElements
Base class: BaseListView

Member UXML attributes

This element has the following member attributes:

Name 타입 설명
sorting-enabled boolean Whether or not sorting is enabled in the multi-column header.

Inherited UXML attributes

This element inherits the following attributes from its base class:

Name 타입 설명
binding-path string Path of the target property to be bound.
fixed-item-height int The height of a single item in the list, in pixels.

This property must be set when using the virtualizationMethod is set to FixedHeight, for the collection view to function. If set when virtualizationMethod is DynamicHeight, it serves as the default height to help calculate the number of items necessary and the scrollable area, before items are laid out. It should be set to the minimum expected height of an item.
focusable boolean True if the element can be focused.
header-title string This property controls the text of the foldout header when using showFoldoutHeader.
reorder-mode UIElements.ListViewReorderMode This property controls the drag and drop mode for the list view.

The default value is Simple. When this property is set to Animated, Unity adds drag handles in front of every item and the drag and drop manipulation pushes items with an animation when the reordering happens. Multiple item reordering is only supported with the Simple drag mode.
reorderable boolean Gets or sets a value that indicates whether the user can drag list items to reorder them.

The default value is false which allows the user to drag items to and from other views when you implement canStartDrag, setupDragAndDrop, dragAndDropUpdate, and handleDrop. Set this value to true to allow the user to reorder items in the list.
selection-type UIElements.SelectionType Controls the selection type.

The default value is SelectionType.Single. When you set the collection view to disable selections, any current selection is cleared.
show-add-remove-footer boolean This property controls whether a footer will be added to the list view.

The default value is false. When this property is set to true, Unity adds a footer under the scroll view. This footer contains two buttons: A “+” button. When clicked, it adds a single item at the end of the list view. A “-” button. When clicked, it removes all selected items, or the last item if none are selected.
show-alternating-row-backgrounds UIElements.AlternatingRowBackground This property controls whether the background colors of collection view rows alternate. Takes a value from the AlternatingRowBackground enum.
show-border boolean Enable this property to display a border around the collection view.

If set to true, a border appears around the ScrollView that the collection view uses internally.
show-bound-collection-size boolean This property controls whether the list view displays the collection size (number of items).

The default value is true. When this property is set to true, Unity displays the collection size as the first item in the list, but does not make it an actual list item that is part of the list index. If you query for list index 0, Unity returns the first real list item, and not the collection size. If showFoldoutHeader is set to true, the collection size field is included in the header instead. You can use this property to debug a ListView because the property indicates whether the data source is linked correctly. In production, the collection size rarely displays as a line item in a ListView.

SA: UnityEditor.UIElements.BindingExtensions.Bind
show-foldout-header boolean This property controls whether the list view displays a header, in the form of a foldout that can be expanded or collapsed.

The default value is false. When this property is set to true, Unity adds a foldout in the hierarchy of the list view and moves the scroll view inside that newly created foldout. You can change the text of this foldout with headerTitle property on the ListView. If showBoundCollectionSize is set to true, the header includes a TextField to control the array size, instead of using the field as part of the list.
tabindex int An integer used to sort focusables in the focus ring. Must be greater than or equal to zero.
virtualization-method UIElements.CollectionVirtualizationMethod The virtualization method to use for this collection when a scroll bar is visible. Takes a value from the CollectionVirtualizationMethod enum.

The default value is FixedHeight. When using fixed height, specify the fixedItemHeight property. Fixed height is more performant but offers less flexibility on content. When using DynamicHeight, the collection will wait for the actual height to be computed. Dynamic height is more flexible but less performant.

This element also inherits the following attributes from VisualElement:

Name 타입 설명
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.
