Tabs

The <Tabs> component is a container component that allows users to switch between content views through tabs. Each tab page corresponds to a content view.

NOTE

This component is supported since API version 7. Updates will be marked with a superscript to indicate their earliest API version.

Child Components

Only the <TabContent> child component is supported.

APIs

Tabs(value?: {barPosition?: BarPosition, index?: number, controller?: TabsController})

Parameters

Name Type Mandatory Description
barPosition BarPosition No Position of the <Tabs> component.
Default value: BarPosition.Start
index number No Initial tab index.
Default value: 0
NOTE
A value less than 0 evaluates to the default value.
The value ranges from 0 to the number of <TabContent> subnodes minus 1.
When this parameter is set to different values, the slide animation for tab switching is enabled by default. To disable the animation, set animationDuration to 0.
Since API version 10, this parameter supports $$ for two-way binding of variables.

BarPosition

Name Description
Start If the vertical attribute is set to true, the tab is on the left of the container. If the vertical attribute is set to false, the tab is on the top of the container.
End If the vertical attribute is set to true, the tab is on the right of the container. If the vertical attribute is set to false, the tab is at the bottom of the container.

Attributes

In addition to the universal attributes, the following attributes are supported.

If the tab bar has the vertical attribute set to false and BottomTabbarStyle specified, the default value is the width of the <Tabs> component.
NOTE
A value less than 0 or greater than the width of the <Tabs> component evaluates to the default value.
barHeight number |Length8+ Height of the tab bar.
The default value varies.
If the tab bar has the vertical attribute set to false and does not have a style specified, the default value is 56vp.
If the tab bar has the vertical attribute set to true and does not have a style specified, the default value is the height of the <Tabs> component.
If the tab bar has the vertical attribute set to false and SubTabbarStyle specified, the default value is 56vp.
If the tab bar has the vertical attribute set to true and SubTabbarStyle specified, the default value is the height of the <Tabs> component.
If the tab bar has the vertical attribute set to true and BottomTabbarStyle specified, the default value is the height of the <Tabs> component.
If the tab bar has the vertical attribute set to false and BottomTabbarStyle specified, the default value is 56vp.
NOTE
A value less than 0 or greater than the height of the <Tabs> component evaluates to the default value.
animationDuration number Duration of the slide animation for tab switching. If this parameter is set, the tab switching animation is played when the user switches between tabs by sliding or clicking. If this parameter is not set, the tab switching animation is played only when the user switches between tabs by sliding.
Default value: 300
NOTE
A value less than 0 or in percentage evaluates to the default value.
divider10+ DividerStyle |null Whether the divider is displayed for the <TabBar> and <TabContent> components and the divider style. By default, the divider is not displayed.
DividerStyle: divider style.
null: The divider is not displayed.

Default value: false
barBackgroundColor10+ ResourceColor Background color of the tab bar.
Default value: transparent
barGridAlign10+ BarGridColumnOptions Visible area of the tab bar in grid mode. For details, see BarGridColumnOptions. This attribute is effective only in horizontal mode. It is not applicable to XS, XL, and XXL devices.

Default value: 24.0
Unit: vp
sm number No Number of columns occupied by a tab on a screen whose width is greater than or equal to 320 vp but less than 600 vp.
The value must be a non-negative even number. The default value is -1, indicating that the tab takes up the entire width of the tab bar.
md number No Number of columns occupied by a tab on a screen whose width is greater than or equal to 600 vp but less than 800 vp.
The value must be a non-negative even number. The default value is -1, indicating that the tab takes up the entire width of the tab bar.

Default value: 0.0
Unit: vp
nonScrollableLayoutStyle LayoutStyle No Tab layout mode of the tab bar when not scrolling in scrollable mode.

BarMode

Name Description
Scrollable The width of each tab is determined by the actual layout. The tabs are scrollable in the following case: In horizontal layout, the total width exceeds the tab bar width; in horizontal layout, the total height exceeds the tab bar height.
Fixed The width of each tab is determined by equally dividing the number of tabs by the bar width (or bar height in the vertical layout).

LayoutStyle10+

Name Description
ALWAYS_CENTER When the tab content exceeds the tab bar width, the tabs are scrollable.
Otherwise, the tabs are compactly centered and not scrollable.
ALWAYS_AVERAGE_SPLITE When the tab content exceeds the tab bar width, the tabs are scrollable.
Otherwise, the tabs are not scrollable, and the tab bar width is distributed evenly between all tabs.
This option is valid only in horizontal mode, and is equivalent to LayoutStyle.ALWAYS_CENTER otherwise.
SPACE_BETWEEN_OR_CENTER When the tab content exceeds the tab bar width, the tabs are scrollable.
When the tab content exceeds half of the tab bar width but still within the tab bar width, the tabs are compactly centered and not scrollable.
When the tab content does not exceed half of the tab bar width, the tabs are centered within half of the tab bar width, with even spacing between, and not scrollable.

Events

In addition to the universal events, the following events are supported.

Name Description
onChange(event: (index: number) =&gt; void) Triggered when a tab is switched.
- index: index of the active tab. The index starts from 0.
This event is triggered when any of the following conditions is met:
1. The <TabContent> component supports sliding, and the user slides on the tab bar.
2. The Controller API is called.
3. The attribute value is updated using a state variable.
4. A tab is clicked.
onTabBarClick(event: (index: number) =&gt; void)10+ Triggered when a tab is clicked.
- index: index of the clicked tab. The index starts from 0.

TabsController

Defines a tab controller, which is used to control switching of tabs. One TabsController cannot control multiple <Tabs> components.

Objects to Import

let controller: TabsController = new TabsController()

changeIndex

changeIndex(value: number): void

Switches to the specified tab.

Parameters

Name Type Mandatory Description
value number Yes Index of the tab. The value starts from 0.
NOTE
If this parameter is set to a value less than 0 or greater than the maximum number, the event will be invalid.
