Zdor Dmitry Valerevich, Savelyeva Ekaterina Vladimirovna

Object: Reveal the meaningful elements of the design technology for a multi-window SDI style application in the Delphi programming environment, illustrate the main stages and technological methods with a specific example. Methods: Analysis and synthesis of special literature on the research problem, generalization and systematization, modeling. Findings: The windowed graphical interface is predominant. When developing a windowed application in Delphi, the main building block of an application window is the form. Multi-window applications can be MDI (Multi Document Interface) style or SDI (Single Document Interface) style. The article reveals the content elements of the design technology for a multi-window SDI style application. The main elements of the described technology include: 1) designing the start window interface; 2) adding a new form (several forms) to the project, designing their interface, taking into account the relationship with other forms of the project; 3) implementation of the interconnection of modules corresponding to the interconnected forms of the project; 4) writing event handlers to implement window functions, including software implementation of the transition between windows of a multi-window application. Conclusions: The article describes the technology for designing a multi-window SDI-style application in the Delphi programming environment. The technology is described using an example of a specific application with an illustration of fragments of program code. The content elements of the presented technology can serve as a practical basis for building a multi-window SDI-style application in the Delphi programming environment. The results obtained can be used in the further development of issues of creating multi-window applications.
