C# class: ScrollView
Namespace: UnityEngine.UIElements
Base class: VisualElement
The following table lists all the supported attributes.
名称 | 类型 | 描述 |
---|---|---|
content-container |
string |
Contains full content, potentially partially visible. |
elasticity |
float |
The amount of elasticity to use when a user tries to scroll past the boundaries of the scroll view. Elasticity is only used when touchScrollBehavior is set to Elastic. |
focusable |
boolean |
True if the element can be focused. |
horizontal-page-size |
float |
This property is controlling the scrolling speed of the horizontal scroller. |
horizontal-scroller-visibility |
string |
Specifies whether the horizontal scroll bar is visible. |
mode |
string |
Controls how the ScrollView allows the user to scroll the contents.ScrollViewMode The default is ScrollViewMode.Vertical .Writing to this property modifies the class list of the ScrollView according to the specified value of ScrollViewMode . When the value changes, the class list matching the old value is removed andthe class list matching the new value is added. |
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 |
string |
Determines if this element can be pick during mouseEvents or IPanel.Pick queries. |
scroll-deceleration-rate |
float |
Controls the rate at which the scrolling movement slows after a user scrolls using a touch interaction. The deceleration rate is the speed reduction per second. A value of 0.5 halves the speed each second. A value of 0 stops the scrolling immediately. |
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#. |
tabindex |
int |
An integer used to sort focusables in the focus ring. Must be greater than or equal to zero. |
tooltip |
string |
Text to display inside an information box after the user hovers the element for a small amount of time. |
usage-hints |
string |
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). |
vertical-page-size |
float |
This property is controlling the scrolling speed of the vertical scroller. |
vertical-scroller-visibility |
string |
Specifies whether the vertical scroll bar is visible. |
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 . |
To see which USS selectors affect the components of the ScrollView at every level of its hierarchy, use the UI Toolkit Debugger:
