What OpenType typographic features does Qt support?

Question

I'm curious whether Qt supports features like alternate figures (tabular or old style).

Answer 1

The short answer is: None.

Qt uses FreeType to render the fonts. While the FreeType library itself provides an OpenType extension, the QFont object in Qt does not provide any API for Open Type extensions.

• See for FreeType: http://freetype.org/opentype/index.html
