B4A Library SD: BindingNavigator (Sqlite GUI Navigator)

This is a first version of the BindingNavigator Library, which wants to somehow reproduce the corresponding BindingNavigator of VB.NET.
What is needed? I want to get something similar to the tools available on VB.NET to link the views to the DB. As in the pictures.



A DataSet Class is available that allows to associate some views (EditText, Label, ImageView, ToggleButton, CheckBox) with specific fields of a Sqlite DataBase.

By scrolling the position of the DataSet the fields will be updated and if the fields in some way undergo a variation by the user, raising the UpdateChange event will in turn be modified in the DataBase.
This very Agevolent construction of GUI related to the DB.

In addition you have a Second ViewCalss NavigatorBar that adds a new Seek view to the design that is linked to the DataSet. Scrolling through the Seek will change all the views linked to the DataSet. And if the UpdateChange eventio is updated, the DB will be updated based on changes in the views linked to the fields.

VERY IMPORTANT:

1. The sql database must always have a Primarykey field, of type int with auto-increment, in the example i call it ID, but it could be called as you want.
   The name of the field that will be the Primarykey must be communicated to the DataSet when call query method.
2. If you use NavigatorBar, in your code you must load FontAwesone, as in the example at post#2, or in the Wish you can have a view set with FontAwesone
