Android Question Treeview control/Scanner library

[PhilE]

First let me say I am new to B4A. I have programmed in Basic for years. I need two controls/tools

1. A Treeview control

2. a Library to control the printer scanner

For Treeview see this https://www.b4x.com/android/forum/threads/class-treeview-class-tree-and-node.19082/
It is not simple to start with if you are new to B4A.
