PowerWeb is an add-on library for web application development in Xbase++. PowerWeb library is function-oriented and implements top-down modular style of programming. Functions and their parameters are very flexible, user-friendly, intuitive and easy to use.

PowerWeb functions represent object abstractions of HTML elements. The functions are HTML helpers which generate the HTML code for HTML elements. They encapsulate most of the properties and events of the HTML elements, which are defined as function parameters. The functions are generalized and automated and create the complete logic of HTML elements. You don't need to know HTML/CSS programming, elements, methods, properties and events. Instead, use PowerWeb functions as building blocks to create fast and efficient HTML programs with a minimum number of code lines and that use the minimum amount of memory resources.

All HTML elements created by PowerWeb functions are fully configurable in Xbase++ language and style without HTML/CSS. Their positions, sizes, fonts, colors, borders, types, aligns and other attributes can be defined by the user, using function parameters. The configuration parameters can be specified at the global level or for each HTML element.

PowerWeb functions implement AJAX (Asynchronous JavaScript and XML) technology which allows clients to asynchronously send requests and receive server responses. In that way, clients can retrieve data and dynamically update parts of a web page without reloading the whole page. PowerWeb uses JSON and HTML formats for data transfer.

PowerWeb library is a web UI framework which allows to create full-fledged web applications in Xbase++ language and style, that will have a modern GUI design and look. PowerWeb functions are HTML helpers that generate the HTML code for web UI components.

PowerWeb library contains multiple modules listed in the following table.

Module	Description
PowerWebUi	User interface
PowerWebGrp	Graphs
PowerWebPrn	Print
PowerWebMail	Send mail

PowerWeb library can be used with Alaska CXP and WAA technologies, and with our PowerComHttp server.

PowerWeb library supports Alaska Xbase++ V.2.0 to V.1.8. It is available in Serbian, English and German language, but can be easy modified by the user in any language.
