<h3>Description</h3>
The <tt>Fl_Value_Input</tt> widget displays a floating point value.
The user can click in the text field and edit it (there is in fact
a hidden <a href="#Fl_Value_Input"><tt>Fl_Value_Input</tt></a> widget with
<tt>type(FL_FLOAT_INPUT)</tt> in there), and when they hit return
or tab the value updates to what they typed and the callback is done.
<p>If <tt>step()</tt> is not zero, the user can also drag the mouse
across the object and thus slide the value. The left button moves one
<tt>step()</tt> per pixel, the middle by <tt>10 * step()</tt>, and the
left button by <tt>100 * step()</tt>. It is then impossible to select
text by dragging across it, although clicking can still move the
insertion cursor.

<h4><a name="Fl_Value_Input.Fl_Value_Input">Fl_Value_Input::Fl_Value_Input(int x, int y, int w, int h, const char *label = 0)</a></h4>
Creates a new <tt>Fl_Value_Input</tt> widget using the given position, size, and
label string. The default boxtype is <tt>FL_NO_BOX</tt>.
<h4><a name="Fl_Value_Input.~Fl_Value_Input">virtual Fl_Value_Input::~Fl_Value_Input()</a></h4>
Destroys the valuator.
<h4><a name="Fl_Value_Input.cursor_color">Fl_Color Fl_Value_Input::cursor_color() const<br>

Get or set the color of the cursor. This is black by default.

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.
