The Wtx is an extension library built expressly for the Wt web development tool kit. The Wt web development tool kit can be found here: https://www.webtoolkit.eu/wt

The Wt tool kit is an incredible tool for building rediculously fast websites using c++. Wt includes an extremely powerful back-end database library for serializing c++ objects directly in to a database. You can read about that here: https://www.webtoolkit.eu/wt/doc/tutorial/dbo.html

The Wt tool kit also includes a very powerful front-end widget library for building websites the "object-oriented way" as well as the "c++ way". You can read about the widget library here: https://webtoolkit.eu/widgets

All that is left for the programmer, then, is to build all the middle-ware connecting the "database" objects to the "user interface" objects... and this is where the Wtx library comes in.

The Wtx library strives to simplify all of the glue logic between the c++ classes and the website user interfaces. It allows the programmer to focus on the operational logic of the programming task, and less on the "grunt work" of binding c++ classes to back-end databases and front-end user interfaces.

This can be best explained by reviewing the documentation for the TableView, where a table-view is constructed easily with a simply table-view-definition and then a simple call to the table view constructor. You can read more about that here: Wtx::TableViewDef
