Ignoring for a moment the rest of the discussion: does such a value 
_make sense_ in the first place?

Qt-provided styles always tried to follow the OS native style, even in 
the sizing of the controls. Arbitrarily resizing controls has always 
been possible, but generally doing that either violates the guidelines 
of the native style (e.g. making a push button 100px high) or breaks the 
widget altogether (making a push button 5px high).

In this light, what's the idea of a global minimum size useful for? A 
native style should rightfully completely ignore it. A non-native style 
could have it a as a tunable parameter, but then, actually, it could 
have _any_ amount of tunable parameters (e.g. have a minimum size for 
buttons, a minimum size for labels, etc.).

Does anyone have more insights?

Thanks,
