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.
