This is a development question, so will very likely get a better answer on the 
KDE developer mailinglist kde-devel.

All parts of the KDE desktop are applications themselves and most of them 
handle events like what you called a custom application.

However some applications need to do a bit more, for example khotkeys should 
receive events even when it doesn't have an active window.

I think this is done by using QApplication::x11EventFilter, but there might be 
a simpler way in some KDE code, or maybe KHotKeys or a similar application 
can be extended to do the logging for you.

So I return to my above suggestion to ask on kde-devel :)

Cheers,
Kevin
