ArkUI Subsystem Changelog

cl.arkui.1 Change in the Effect of Setting constraintSize minWidth Alone in the <TextInput> or <TextArea> Component

Access Level

Public

Reason for Change

The effect of constraintSize minWidth on API version 10 does not meet the application expectation and needs to be corrected on API version 11.

Change Impact

This change is a non-compatible change.

Change Since

OpenHarmony SDK 4.1.3.1

Key API/Component Changes

TextInput/TextArea

Before change: If constraintSize({minWidth:100}) is set and the width attribute is not specified for a <TextInput> component, the width of the component is the maximum width passed by the parent component.

After change: If constraintSize({minWidth:100}) is set and the width attribute is not specified for a <TextInput> component, the width of the <TextInput> component is 100 at minimum when the width of the parent component is greater than or equal to 100, and automatically increases to adapt to the content.

cl.arkui.2 Change of hideNavBar Effectiveness for the <Navigation> Component

Access Level

Public

Reason for Change

The effectiveness of the hideNavBar API is increased from the dual-column mode only to both single-column and dual-column modes.

Change Impact

This change is a non-compatible change. Before change: The hideNavBar API has no effect in the single-column mode.
After change: The hideNavBar API works for both single-column and dual-column modes. If no target page is available, using this API may result in a blank screen.

API Level

Change Since

OpenHarmony SDK 4.1.3.1

Adaptation Guide

When this API is used, the navigation bar, including the title bar, content area, and toolbar, is hidden. In this case, if there is a navigation destination page in the navigation stack, the page at the top of the stack is displayed. Otherwise, a blank screen is displayed In versions earlier than API version 11, this API takes effect only in dual-column mode. Since API version 11, this API works for the single-column, dual-column, and adaptive modes. If a blank screen occurs due to the use of this API, you can remove this API or provide a navigation destination page in the navigation stack.
