Qt
DetEdit is built with Qt 6.11.1 under a commercial licence from The Qt Company Ltd. Qt itself includes third-party components — among them FreeType, HarfBuzz, PCRE2, zlib and libpng — each under its own licence. The complete list of those components, with their versions, licences and copyright notices, is in qt-third-party.txt. It was generated with qtattributionsscanner from the Qt sources for the modules DetEdit uses, and needs to be regenerated when the Qt version changes.
Icons
The application icons are derived from Google’s Material Symbols and Material Icons, licensed under the Apache License 2.0. Some icons have been recoloured or resized; the artwork is otherwise unmodified.
Fonts
The application bundles Open Sans, licensed under the SIL Open Font License 1.1. The licence requires that this notice and the licence text accompany the font, and that the font is not sold on its own.
