如何使用

基础使用

只需要将组件包裹你的需要滚动内容，设置好容器大小，内容将自动允许滚动并设置滚动条（默认垂直滚动）。

TIP

因为容器默认占满父级，因此在未设置高度的容器中，组件可能无法撑开父级，需要设置一个确定的高度。

自定义滚动条

如果你希望换掉内置的滚动条，使用自己的滚动条组件，可以通过插槽 scrollBarX 和 scrollBarY 来实现。

插槽会传出当前滚动条滚动位置和计算长度数据 (scrollBarValue)，你可以根据这个百分比来计算滚动条的显示位置；传出 onScroll 回调用于控制滚动。。

scrollBarValue 结构如下：

名字	类型	类型
show	boolean	是否显示滚动条
size	number	滚动条计算长度（百分比，0-100）
sizeRaw	number	滚动条计算长度（像素）
pos	number	滚动条滚动位置（百分比，0-100）

onScroll 结构如下：

参数	类型
pos	number

<template>
  <ScrollRect class="long-content" scroll="both">
    <ScrollContent />
    <template #scrollBarY="{ scrollBarValue, onScroll }">
      <MyScrollBar :value="scrollBarValue.pos" :size="scrollBarValue.size" @update:value="onScroll" />
    </template>
  </ScrollRect>
