The Fl_Adjuster widget was stolen from Prisms, and has proven |

to be very useful for values that need a large dynamic range. |

|
<P>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. |
