Returns the tree view node whose row is at a point, or 0 over empty space or a scroll bar. The whole row counts, including its indent and expand button, just as a click there selects the node. Collapsed branches hide their children, so only visible rows are ever returned. Use it to find the node under a right-click. A tree posts a $201 mouse-down event with EventData()=2 for the right button, and EventX() and EventY() are already in the logical pixels this command expects, so a context menu can act on the row that was clicked rather than on the old selection: If EventID()=$201 And EventSource()=tree And EventData()=2 Then node=TreeViewNodeAt(tree,EventX(),EventY()) If node Then SelectTreeViewNode node ShowPopupMenu menu,tree,EventX(),EventY() EndIf EndIf The World Editor opens its object menu this way from its Scene hierarchy.
