A simple text popup tip.
## When To Use
2017-09-18 10:28:22 +08:00
- 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 sometime not work on HOC?
2017-01-22 14:26:46 +08:00
2017-09-18 10:28:22 +08:00
Please ensure that the child node of `Tooltip` accepts `onMouseEnter` , `onMouseLeave` , `onFocus` , `onClick` events.
2023-07-25 11:38:38 +08:00
### 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.
