How to reliably scroll Virtual TreeView to the bottom?
A TVirtualStringTree object with custom node height, How to reliably scroll Virtual TreeView to the bottom (ie the scrollbar gets to the bottom)?
I tried calling tree1.FullExpand then tree1.ScrollIntoView.(tree1.GetLast) , but it does not work.
Thank you in advance.
ScrollIntoView works well for me. You can also try tree1.FocusedNode := tree1.GetLast;
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.
尝试这个：
SendMessage(VST.Handle, WM_VSCROLL, SB_BOTTOM, 0);
PostMessage(VST.Handle, WM_VSCROLL, SB_BOTTOM, 0);
这也应该工作：
tree1.TopNode := tree1.GetLast
