We do that all over the place with Qt. We use a lot of internals.

In this case, what this hack is about is to get the QPrintDialog -- which 
is a QDialog -- find the widget called "generalWidget", add a QTabWidget 
as its parent and insert it into the dialog. And keep the button box in 
the proper place.

This obviously depends on the internal construction of the dialog. That's 
why it won't work with the native dialogs.

The only alternative I can see is to write a KPrintDialog. We won't be 
able to get rid of it until KDE 5.
