[Interest] [OS X] using Qt in a Preference Pane and that prefPane from a Qt application?

[René J. V. Bertin]

Hi,

I'd like to experiment writing a Preference Pane for Qt-based apps, ideally 
using the pane's window as the source for a QWidget (or QWindow or ...) so it 
can be populated with existing Qt objects. Is that feasible without a whole slew 
of high-maintenance hacks and has something like this been done before 
(preferably using CMake)?

Thanks,
René
