Unlike some other view controls, the B4J TreeTableView does not have a ScrollTo (exposed). [Found partial solution via searching] Use JavaObject and access the scrollTo [Reviewed JavaFX source for TTV to realize the following complete solution] B4X: Copy Dim jo As JavaObject = TreeTableView1 ' the TreeTableView Dim iTTVindex As Int = jo.RunMethod("getRow",Array(tti)) ' for TreeTableItem tti jo.RunMethod("scrollTo",Array(iTTVindex)) Last edited: May 30, 2021
