<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.
|
||
|
|
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.

<h4><a name="Fl_Adjuster.soft">uchar Fl_Adjuster::soft() const<br>
|
||
|
|
void Fl_Adjuster::soft(uchar)</a></h4>
|
||
|
|
|
||
|
|
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.
