The above patch alone does not help as the database isn't used directly. Instead, requests are forwarded to Fontconfig, which is a good thing.
It then maps Qt weights back to FC weights: http://qt.gitorious.org/qt/qt/blobs/4.8/src/gui/text/qfontdatabase_x11.cpp#line1489 And the mapping looks as follows: 0.0 => Medium 0.0 ÷ 36.5 => Light 36.5 ÷ 56.5 => Medium 56.6 ÷ 69.0 => DemiBold 69.0 ÷ 81.0 => Bold 81.0 ÷ ∞ => Black An attentive reader will find that there's no Regular there... Which means Qt will _never_ request a Regular font from Fontconfig, so as long as there's anything closer to Medium than Regular (e.g. Medium), it will choose that over Regular. What's more, it defaults to Medium, which seems a common pattern in that code: http://qt.gitorious.org/qt/qt/blobs/4.8/src/gui/text/qfontdatabase_x11.cpp#line777 http://qt.gitorious.org/qt/qt/blobs/4.8/src/gui/text/qfontdatabase_x11.cpp#line1069 http://qt.gitorious.org/qt/qt/blobs/4.8/src/gui/text/qfontdatabase_x11.cpp#line1078 http://qt.gitorious.org/qt/qt/blobs/4.8/src/gui/text/qfontdatabase_x11.cpp#line1491 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/744812 Title: FontConfig/Qt stack choke on Ubuntu Medium font meta-data (No medium in Inkscape and too bold in Qt apps) To manage notifications about this bug go to: https://bugs.launchpad.net/linuxlibertine/+bug/744812/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
