16.2 VDC

VDC (Ventas Display Client) is a rich thin client application which provides a Graphical User Interface (GUI) to Aubit4GL programs.
Ventas have initiated the development of a front end graphic user interface to display both Informix 4GL traditional forms and a newly devised, more graphics-oriented XML format which displays standard GUI objects such as pull-down menus, buttons, popup lists, arrayed vertically, horizontally, or in tabbed pages.
The VDC frontend is written in C++ and uses the QT4 libraries to implement the graphics. QT from Trolltech is available in Linux, Apple OSX, and Microsoft so that the VDC front ends are able to be on platforms separate from the server running the Aubit4GL programs.
