260  Custom Style Element runtime extension:
261  We reserve one StyleHint to let the effective style inform widgets whether it supports certain
262  string based style elements.
263  As this could lead to number conflicts (i.e. an app utilizing one of the hints itself for other
264  purposes) there're various safety mechanisms to rule out such interference.
265 
266  1) It's most unlikely that a widget in some 3rd party app will accidentally call a general
267  QStyle/K4Style styleHint() or draw*() and (unconditionally) expect a valid return, however:
268  a. The StyleHint is not directly above Qt's custom base, assuming most 3rd party apps would
269  - in case - make use of such
270  b. In order to be accepted, the StyleHint query must pass a widget with a perfectly matching
271  name, containing the typical element prefix ("CE_", etc.) and being supported by the current style
272  c. Instead using Qt's fragile qstyleoption_cast on the QStyleOption provided to the StyleHint
273  query, try to dump out a string and hope for the best, we now manipulate the widgets objectName().
274  Plain Qt dependent widgets can do that themselves and if a widget uses K4Style's convenience access
275  functions, it won't notice this at all
276 
277  2) The key problem is that a common KDE widget will run into an apps custom style which will then
278  falsely respond to the styleHint() call with an invalid value.
279  To prevent this, supporting styles *must* set a Q_CLASSINFO "X-KDE-CustomElements".
280 
281  3) If any of the above traps snaps, the returned id is 0 - the QStyle default, indicating
282  that this element is not supported by the current style.
283 
284  Obviously, this contains the "diminished clean" action to (temporarily) manipulate the
285  objectName() of a const QWidget* - but this happens completely inside K4Style or the widget, if
286  it does not make use of K4Styles static convenience functions.
287  My biggest worry here would be, that in a multithreaded environment a thread (usually not being
288  owner of the widget) does something crucially relying on the widgets name property...
289  This however would also have to happen during the widget construction or stylechanges, when
290  the functions in doubt will typically be called.
291  So this is imho unlikely causing any trouble, ever.
