The QwtScaleDraw object of the slider knows the ticks and how to map a value to its widget position.

ok...but when I try to use the method const QwtScaleDraw * scaleDraw () const, comiling I have an error, the compiler recognize it as private!

Obviously you want to access the non const method, that is private. Call the const method instead.
