public procedure TCustomListBox.MakeCurrentVisible; |
MakeCurrentVisible is a procedure used to ensure that the current item selected in the control is also visible. The current selection is the value in Items stored at the position in ItemIndex. No actions are performed in the method when ItemIndex is out of bounds.
MakeCurrentVisible calls ItemFullyVisible to determine if the item at ItemIndex is already visible in the scrollable list. No additional actions are needed in the method when the item is already visible. Otherwise, the value in ItemIndex is assigned to the TopIndex property which causes the selected item to scroll to the top of the visible area in the list box.
