FindChild() is the method for finding the child widget of a container. 
TreeView is internally a Container, as every widget written in Gambas, 
even if it has actually no children (except when you edit an item, where 
a temporary text field is created).

Again, Treeview items are -not- widgets, they are not children of the 
TreeView.
