| screenX<sup>(deprecated)</sup> | number | X coordinate of the touch point relative to the upper left corner of the application window.<br>This API is deprecated since API version 10. You are advised to use **windowX** instead. |
| screenY<sup>(deprecated)</sup> | number | Y coordinate of the touch point relative to the upper left corner of the application window.<br>This API is deprecated since API version 10. You are advised to use **windowY** instead. |

| force | number | Touch force of the historical point.<br>Default value: **0**<br>Value range: [0,1]. A larger value indicates a greater touch force.<br>The support for this API varies by device. Currently, it is only available on tablets.|
| timestamp | number | Timestamp of the historical point. It is the interval between the time when the event is triggered and the time when the system starts, in nanoseconds. |
## cl.arkui.1 Change of the ScrollState Enum Rules
The table lists the rules for the **ScrollState** enums in API version 9 and earlier versions:
| Name | Description |
| ------ | ------------------------------ |
| Idle | Idle. The list enters this state when an API in the controller is used to scroll the list or when the scrollbar is dragged. |
| Scroll | Scrolling. The list enters this state when the user drags the list to scroll. |
| Fling | Inertial scrolling. The list enters this state when inertial scrolling occurs or when the list bounces back after being released from a fling.|
The table lists the rules for the **ScrollState** enums in API version 10 and later versions:
| Name | Description |
| ------ | ------------------------------ |
| Idle | Idle. The list enters this state when it is not scrolling or an API in the controller that does not apply an animation is called. |
| Scroll | Scrolling. The list enters this state when the user drags the list, scrollbar, or mouse wheel to scroll the list. |
| Fling | Inertial scrolling. The list enters this state when: inertial scrolling occurs after a fling; the list bounces back after being released from a fling; inertial scrolling occurs after quick dragging of the built-in scrollbar; scrolling occurs after an API in the controller that applies an animation is called.|
The table below lists the changes in the **ScrollState** enums.
| Scenario | API Version 9 and Earlier |API Version 10 and Later |
| Scrolling by the scrolling controller (with animation) | Idle | Fling |
| Scrolling by the scrolling controller (without animation) | Idle | Idle |
**Change Impact**
1.**ScrollState** is available since API version 7. The change is introduced in API version 10 and does not affect the use in API version 9 and earlier versions.
2. Since API version 10, the use of **ScrollState** is affected in the **onScroll** event of the **\<List>** component.
When the **\<List>** component is bound to the **onScroll** event and reports the scrolling status through the event, it must comply with the new rules since API version 10.
## cl.arkui.2 Change of Use Case Restrictions of ArkUI Built-in Components
Restricted the use of ArkUI built-in components to the build methods of structs, **pageTransition** method, or @Builder decorated functions.
**Example**
```
@Entry
@Component
struct Index {
build() {
Row() {
}
}
}
// ERROR:UI component 'Text' cannot be used in this place.
Text('Hello World')
```
**Change Impact**
A build error will occur if a built-in component is not used in a build method of a struct, **pageTransition** method, or any @Builder decorated function.
**Key API/Component Changes**
N/A
**Adaptation Guide**
Use ArkUI built-in components only in build methods of structs, **pageTransition** methods, and @Builder decorated functions.
## cl.arkui.3 \<RowSplit> and \<ColumnSplit> Component Layout and Behavior Changes
1. Changed the default size of the **\<RowSplit>** or **\<ColumnSplit>** component on the cross axis from adapting to the parent component size to adapting to the child component size.
2. Changed how the child components behave when the**\<RowSplit>** or **\<ColumnSplit>** component's divider is dragged:
- Before the change, the child components are translated without being compressed or stretched.
- After the change, the child components are compressed and stretched.
3. Changed the clipping area of child components for when the **clip** attribute is used to clip the child component content that exceeds the component area: For **\<RowSplit>**, the clipping area is changed from the right side to both the left and right sides of the child component area;
For **\<ColumnSplit>**, the clipping area is changed from the bottom to both the top and bottom of the child component area.
**Change Impact**
The preceding changes affect the **\<RowSplit>** and **\<ColumnSplit>** components in API version 10 and later versions.
