类型别名

`MatTabBodyOriginState`

原始状态是一个内部使用的状态，它在新的选项卡本体上设置，表明它是从前一个选定索引的左侧还是右侧开始的。例如，如果选定索引设置为 1，并且在索引 2 处创建并选定了一个新选项卡，则该选项卡本体的原点是右侧，因为它的索引大于之前选择的索引。

The origin state is an internally used state that is set on a new tab body indicating if it began to the left or right of the prior selected index. For example, if the selected index was set to 1, and a new tab is created and selected at index 2, then the tab body would have an origin of right because its index was greater than the prior selected index.

type MatTabBodyOriginState = 'left' | 'right';

`MatTabBodyPositionState`

这些位置状态在内部用作选项卡本体的动画状态。将位置状态设置为 left、right 或 center，会把选项卡本体从当前位置转移到各自的状态。如果没有当前位置（对于新的选项卡本体是 void），那么它的状态就没有过渡动画了）。

These position states are used internally as animation states for the tab body. Setting the position state to left, right, or center will transition the tab body from its current position to its respective state. If there is not current position (void, in the case of a new tab body), then there will be no transition animation to its state.

如果新的选项卡本体应该立即以动画过渡到居中位置，那么就可以使用 left-origin-center 或 right-origin-center，它会用 left 或 right 作为伪造的先前状态。

In the case of a new tab body that should immediately be centered with an animating transition, then left-origin-center or right-origin-center can be used, which will use left or right as its psuedo-prior state.

type MatTabBodyPositionState = 'left' | 'center' | 'right' | 'left-origin-center' | 'right-origin-center';

`ScrollDirection`

当标头上的选项卡超出标头宽度时，可以滚动的方向。 'after' 会把标头滚动到选项卡列表的末尾，'before' 会滚动到列表的开头。

The directions that scrolling can go in when the header's tabs exceed the header width. 'After' will scroll the header towards the end of the tabs list and 'before' will scroll towards the beginning of the list.

type ScrollDirection = 'after' | 'before';

`MatTabHeaderPosition`

选项卡标头的可能位置。

Possible positions for the tab header.

type MatTabHeaderPosition = 'above' | 'below';

常量

`MAT_TABS_CONFIG`

这个注入令牌可以用来提供选项卡模块的默认选项。

Injection token that can be used to provide the default options the tabs module.

const MAT_TABS_CONFIG: InjectionToken<MatTabsConfig>;
