Harfbuzz is responsible for layout (positioning) of glyphs, not
rendering them to bitmaps.

Hi,
Qt can be built with or without support for text rendering using
harfbuzz. Qt4 and Qt5 seem to differ slightly in this aspect, but from
what I understand both can be made to use harfbuzz at runtime even
when not compiled to use it (by default).
I'd like to test this, as it would probably let t

Runtime, no.
But the OS is a factor. Remember OS X uses Mach-O, and since 10.4 or something
it has used a two-l

That was the culprit. The dynamically-casted-to class (Okular::ViewerInterface
in this case) didn't have an

You might be hitting some undefined behavior. Do your classes have
virtual functions? If not, dy
Hi,
I have an issue with some KDE4 code (built against Qt 4.8.6) where a
dynamic_cast fails on OS X but not on Linux (be it with gcc or clang
3.5). In a nutshell:
class D: public class C, public class B, public class A;
with C inheriting QObject (ultimately), the others being "root
classes". The
