### 17.7 Thumbwheel Object

Thumbwheel is another valuator that can be useful for letting the user indicate a value between some fixed bounds. Both horizontal and vertical thumbwheels exist. They have a minimum, a maximum and a current value (all floating point values). The user can change the current value by rolling the wheel.
