For the record: You'll also have to specify a theme name to use.
QIcon::setSearchPaths() and QIcon::themeName().
Which of course adds a rat-tail of problems, such as supporting primary,
and fallback themes, user preferred themes, etc.. At least if you're
looking for more than the quick-and-dirty.

Ok, disregarding the fonts and all, and focusing on the icons, only:
Sweet. So that works without adjustments to the code. _But_ can I just
depend on this, then? Or won't this interfere with pure Qt apps, once
For our binary standalone package, we won't care. But for playing
nice with MacPorts I'll have to go the search paths + theme name route
outlined above, in addition, right?
I wonder: Would it be feasible to create something (a framework?) where
I can simply write:
and be done with? Including all fonts, icons, dbus, whatever comes up
now or in the future?

In use, yes, but it would make it easier to diagnose the error
condition. Essentially isNull() vs isEmpty().

Umm, no? OSX 10.9, here.

That's still in the frontend process. Just the backend as seen by the
frontend, so to speak. The directory layout may not be all that
helpful, indeed, but part of the problem is that backend and frontend
processes share some of the same code (think of it as the protocol), so
it's not trivial to come up with a clear layout.
