The following table lists all the supported attributes.
| 名称 | 类型 | 描述 |
|---|---|---|
binding-path |
string |
Path of the target property to be bound. |
content-container |
string |
child elements are added to this element, usually this |
direction |
string |
This is the actual property to contain the direction of the slider. |
focusable |
boolean |
True if the element can be focused. |
high-value |
float |
This is the maximum value that the slider encodes. |
inverted |
boolean |
This indicates whether or not this slider is inverted. For an inverted horizontal slider, high value is located to the left, low value is located to the right For an inverted vertical slider, high value is located to the bottom, low value is located to the top. |
label |
string |
The string representing the label that will appear beside the field. |
low-value |
float |
This is the minimum value that the slider encodes. |
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. |
page-size |
float |
This is a generic page size used to change the value when clicking in the slider. |
picking-mode |
string |
Determines if this element can be pick during mouseEvents or IPanel.Pick queries. |
show-input-field |
boolean |
The visibility of the optional field inside the slider control. Set this property to true to display a numerical text field that provides another way to edit the slider value. |
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). |
value |
float |
The actual value of the slider. |
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. |
