Every sgcUI product exposes its content to Microsoft UI Automation, the API that screen readers such as Narrator and NVDA use, can be operated with the keyboard, with the exceptions listed under known limitations, and follows the Windows high contrast themes. This page states what we commit to, what is covered, what is not covered yet, and links the conformance report of each platform.
eSeGeCe builds sgcUI so that the applications made with it can be used by everyone, including people who use a screen reader, people who use only the keyboard and people who need strong contrast. The accessibility support is part of every product and every edition, the free Community edition included, and it is on by default: drop a control on a form and it is accessible, with no setup and no extra cost while no accessibility client is running.
The support is designed to meet the requirements of EN 301 549 and of WCAG 2.1 level AA that apply to software components: name, role, value and state of every element, keyboard operation, visible focus, non text contrast, and the use of the system colours. We publish an accessibility conformance report for each platform and update it when the components change.
The final conformance of your application also depends on how you use the components: give every control a meaningful name, keep a logical tab order on your forms, and do not convey information by colour alone in the data you show.
sgcGrid, sgcPivotGrid, sgcCharts, sgcGauges, sgcDashboard, sgcPlanner, sgcDiagram, sgcWizard, sgcNavigation, sgcToolbar, sgcEditors and sgcMaps.
The components expose their content to Microsoft UI Automation, the accessibility interface of Windows that screen readers such as Narrator and NVDA and the testing tools of Microsoft use: a grid is exposed as a table with rows, cells and headers, a chart as a list of series and points, a planner as a list of items, and so on. Older clients that only speak MSAA are served through the bridge Windows provides between UI Automation and MSAA.
utHighContrast theme forces it. Right to left layouts and high DPI are supported.The conformance reports follow the international edition of VPAT 2.5 and cover WCAG 2.1 level A and AA, the Revised Section 508 standards and EN 301 549 V3.2.1 (2021-03). Most criteria are supported, some are partially supported, and the remarks of each row say what the components provide and what is the responsibility of the application developer.
The reports are based on a review of the implementation against its design, product by product, on automated in process tests in the product QA suites (names, roles, values, states, patterns, element trees, bounds under right to left layouts and at 100 to 200 percent DPI, keyboard alternatives, focus indicator, high contrast rendering and the zero cost rule when no client listens), and on the measured contrast of the theme colours.
We tested the components with the NVDA 2026.2 screen reader on all platforms (Delphi VCL, C++Builder, FireMonkey on Windows, .NET WinForms, WPF and Avalonia). We also scanned them with Accessibility Insights for Windows and AxeWindows 2.4.2 and fixed all real defects found. Narrator was not tested. The conformance reports state the result for each criterion.
As stated in the conformance reports.

If a control is hard to use with your screen reader, your keyboard or your contrast settings, or if you need a report in another format, write to info@esegece.com. Tell us the product, the platform, the version and the assistive technology you use, and we will look into it.
This statement was prepared in October 2026 for sgcUI 2026.10. The Avalonia results were tested again with Avalonia 12.1.4 on 12 October 2026.
