问题描述

具有自定义节点高度的TVirtualStringTree对象,如何可靠地将Virtual TreeView滚动到底部(即滚动条到底部)?

A TVirtualStringTree object with custom node height, How to reliably scroll Virtual TreeView to the bottom (i.e. the scrollbar gets to the bottom)?

我尝试调用 tree1.FullExpand 然后 tree1.ScrollIntoView。(tree1.GetLast) ,但不起作用。

I tried calling tree1.FullExpand then tree1.ScrollIntoView.(tree1.GetLast), but it does not work.

提前谢谢。

推荐答案

ScrollIntoView适用于我。您还可以尝试 tree1.FocusedNode:= tree1.GetLast;

ScrollIntoView works well for me. You can also try tree1.FocusedNode := tree1.GetLast;

您是否在OnMeasureItem事件中设置自定义节点高度?
如果不起作用,尝试将树的DefaultNodeHeight设置为较大的值,并在OnMeasureItem事件中将其更改为较低。我注意到树更好地重新计算滚动条的长度。

Are you setting custom node height in OnMeasureItem event?If it doesn't work, try to set tree's DefaultNodeHeight to the bigger value and in OnMeasureItem event change it to lower. I noticed that tree recalculates scrollbar's length better that way.
