滚动条由滚动箭头按钮, 滚动滑块以及滚动滑块容器组成。Spread 的滚动条支持以下行为: 点击滚动箭头按钮滚动,拖拽滚动滑块滚动,以及点击滚动滑块和滚动箭头按钮之间的区域进行滚动。这些动作将促成以下滚动效果:
每点击滚动箭头按钮一次将会滚动表单中的一行或者一列。
上下(或左右)拖动滚动滑块将平滑上下(或左右)滚动表单行列。
每点击滚动滑块与滚动箭头按钮中间区域一次将会滚动表单一页。
你可以设置 showVerticalScrollbar 和 showHorizontalScrollbar 选项来控制是否显示滚动条。
SpreadJS 在你拖拽滚动滑块过程中可以显示滚动提示条。你可以设置 showScrollTip 选项来设置以何种方式显示滚动提示条。在拖拽滚动滑块的过程中,滚动提示条将显示当前可见区域的最顶行和最左列的索引值。
你可以设置 scrollbarMaxAlign 和 scrollbarShowMax 选项来限制滚动的区域。
scrollbarMaxAlign: 滚动条是否对齐视图中表单的最后一行或一列。
scrollbarShowMax: 是否基于表单全部的行列总数显示滚动条。
你可以使用 scrollIgnoreHidden 选项来控制滚动条是否忽略隐藏的行或者列。
以下信息将被视为隐藏:
行高为 0
列宽为 0
行/列的 visible 属性为 false
被收起的分组行列
被筛选掉的行
