Fl_Scrollbar has a value(int) member function that allows to give it integer values. It also inherits from its superclass Fl_Valuator a value(double) member function that gives it a double value.
Do as follows: Fl_Scrollbar *sb; double d = 45.2; ((Fl_Valuator*)sb)->value(d); > Hi there, > > This may be a stupid question. I'm fairly new to C++.

It's not a big concern.
