Šio darbo tikslas yra sukurti metodą, kuris teiktų galimybę kuo didesnę vartotojo sąsajos dalį apibrėžti deklaratyviai (komponentų kūrimas, įvykių klausytojų registravimas, komponentų tarpusavio sąryšių apibrėžimas ir vizualus komponentų išdėstymas languose). Darbe išanalizuotos įvairios komponentinės architektūros bei išraiškingą vartotojo sąsajos apibrėžimą įgalinantys sprendimai. Apibrėžta ir įgyvendinta architektūra leidžianti kurti deklaratyviai apibrėžiamus vartotojo sąsajos komponentus, kurie deklaruoja savo elgesį ir gali bendrauti tarpusavyje pranešimų pagalba. Rezultate buvo sukurta sistema, kuri leidžia kurti taikomąsias programas su Java Swing vartotojo sąsaja, naudojantis beveik vien tik deklaratyviais taikomosios programos dalių apibrėžimais. Sukurtos sistemos konfigūracijos galimybės leidžia sumažinti komponentų manipuliacijai skirto Java kodo poreikį. / A part of a user interface can be created using declarative means. The main goal of this paper is to maximize that portion. To do that, said means would be used to create components, register event listeners, describe relationships between components and layout them in windows. Various component-based architectures and existing solutions for declarative user interface definition were analyzed. As a result, an architecture was defined which allows user interface components to be created using a declarative approach. These components define their behavior and use messages to communicate with each other. The outcome was a system, which can create Java Swing applications using mostly declarative definitions of various parts of said applications. This system provides various configuration options that reduce the need of writing Java code for component manipulation.

The target of this project was to generate a prototype, which would model the elements of the user interface based on the information flow specification. The system is programmed using MS Visual Basic for Applications, its’ graphical environment is MS Visio 2000 and the elements of GUI for modeling are taken from MS Visio 2000 stencil WUI (wui.vss). The created module allows for easy modeling of graphical user interface elements for the data source, which is selected from the database. The processing stages of the data sources are illustrated using MS Visio 2000 documents’ windows, – one window for each stage. In the database, the elements of GUI are associated with the data source processing stages they are related to, i.e. the ones that they are present in. It means, that when working with the system, after selecting the desired data source and its processing stages one wants to model, the system generates the forms with associated GUI elements. This work was being done in the order of the scientific group of Information systems design, which analyses the design of the Information systems in the wide context of requirements engineering, process and data structures specification.
