+| aspectRatio | number | Aspect ratio of the component, which can be obtained using the following formula: Width/Height.
Since API version 9, this API is supported in ArkTS widgets.
The default value varies by API version.
API version 9 and earlier: **1.0**
API version 10: none
**NOTE**
This attribute does not take effect when it is not set or is set to an invalid value.
For example, if a **\** component has only its width set and does not have any child component, then when **aspectRatio** is not set or is set to a negative value, the height of the **\** component is 0. |
| displayPriority | number | Display priority for the component in the layout container. When the space of the parent container is insufficient, the component with a lower priority is hidden.
The digits after the decimal point are not counted in determining the display priority. That is, numbers in the [x, x + 1) range are considered to represent the same priority. For example, **1.0** and **1.9** represent the same priority.
Since API version 9, this API is supported in ArkTS widgets.
**NOTE**
This attribute is valid only for the **\**, **\**, and **\** (single-row) container components.|
