## When To Use
- The tip is shown on mouse enter, and is hidden on mouse leave. The Tooltip doesn't support complex text or operations.
- To provide an explanation of a `button/text/operation`. It's often used instead of the html `title` attribute.

## FAQ
### Why does the warning findDOMNode is deprecated some times appear in strict mode?
This is due to the implementation of `rc-trigger`. `rc-trigger` forces children to accept ref, otherwise it will fall back to findDOMNode, so children need to be native html tags. If not, you need to use `React.forwardRef` transparently passes `ref` to native html tags.
### Why sometime not work on HOC?
Please ensure that the child node of `Tooltip` accepts `onMouseEnter`, `onMouseLeave`, `onPointerEnter`, `onPointerLeave`, `onFocus`, `onClick` events.
### What's the placement logic?
It will follow `placement` config when screen has enough space. And flip when space is not enough (Such as `top` to `bottom` or `topLeft` to `bottomLeft`). Single direction such as `top` `bottom` `left` `right` will auto shift on the view:
<img alt="shift" height="200" src="https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*sxaTTJjLtIMAAAAAAAAAAAAADrJ8AQ/original" />
When `placement` is set to edge align such as `topLeft` `bottomRight`, it will only do flip but not do shift.
### Why Tooltip not update content when close?
Tooltip will cache content when it is closed to avoid flicker when content is updated:
```jsx
// `title` will not blink when `user` is empty
<Tooltip open={user} title={user?.name} />
```
<div>
<img alt="no blink" height="50" src="https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*KVx7QLOYwVsAAAAAAAAAAAAADrJ8AQ/original" />
</div>
If need update content when close, you can set `fresh` property ([#44830](https://github.com/ant-design/ant-design/issues/44830)):
```jsx
<Tooltip open={user} title={user?.name} fresh />
```
<div>
<img alt="no blink" height="50" src="https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*rUbsR4xWpMsAAAAAAAAAAAAADrJ8AQ/original" />
</div>
