QAbstractSlider::setRange ( int min, int max ) should be a slot

QAbstractSlider defines a signal rangeChanged ( int min, int max )
and a public method setRange ( int min, int max )

Unforturnately, setRange ( int min, int max ) is not declared as a slot, so it is not possible to synchronize two sliders/Scrollbars by connecting them like this:

connect(scrollbar1, SIGNAL(rangeChanged ( int , int)), scrollbar2, SLOT(setRange(int, int)));

The other slider property 'value' has the signal slot duo:
SLOT setValue ( int )
SIGNAL valueChanged ( int value )

I would expect the range property to have the same.
