.UIX File

File extension uix is mainly related to uiXML, an XML language for programming UIX applications.

uiXML builds on top of the other UIX technologies, providing an XML language for specifying user interfaces and linking them to data and events. uiXML provides a declarative alternative to creating web applications programmatically with the UIX Java APIs. The pages, events, and any other items defined with uiXML elements are all transformed into Java objects behind the scenes and are thus treated equally by UIX. No compilation is required.
