The Fl_Adjuster widget was stolen from Prisms, and has proven to be very useful for values that need a large dynamic range.

FLTK Adjuster Widget

When you press a button and drag to the right the value increases. When you drag to the left it decreases. The largest button adjusts by 100 * step(), the next by 10 * step() and that smallest button by step(). Clicking on the buttons increments by 10 times the amount dragging by a pixel does. Shift + click decrements by 10 times the amount.


Fl_Adjuster::Fl_Adjuster(int x, int y, int w, int h, const char *label = 0)

Creates a new Fl_Adjuster widget using the given position, size, and label string. It looks best if one of the dimensions is 3 times the other.

virtual Fl_Adjuster::~Fl_Adjuster()

Destroys the valuator.

uchar Fl_Adjuster::soft() const
void Fl_Adjuster::soft(uchar)

If "soft" is turned on, the user is allowed to drag the value outside the range. If they drag the value to one of the ends, let go, then grab again and continue to drag, they can get to any value. Default is one.
