<H3>Description</H3>
|
|
The <TT>Fl_Adjuster</TT> widget was stolen from Prisms, and has proven
|
|
to be very useful for values that need a large dynamic range.
|
|
<P ALIGN=CENTER><IMG SRC="adjuster1.gif" ALT="Fl_Adjuster widget."></P>
|
|
<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
|
|
<TT>100 * step()</TT>, the next by <TT>10 * step()</TT> and that
|
|
smallest button by <TT>step()</TT>. Clicking on the buttons
|
|
increments by 10 times the amount dragging by a pixel does. Shift +
|
|
click decrements by 10 times the amount.

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

|
|
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.
