<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.
