<H3>Description</H3>

2002-05-25 16:17:18 +04:00
|
|
|
|
|
|
|
|
<P>The <TT>Fl_Value_Input</TT> widget displays a numeric value.
|
|
|
|
|
The user can click in the text field and edit it - there is in
|
|
|
|
|
fact a hidden <A
|
|
|
|
|
href="Fl_Input.html#Fl_Input"><TT>Fl_Input</TT></A> widget with
|
|
|
|
|
<TT>type(FL_FLOAT_INPUT)</TT> or <TT>type(FL_INT_INPUT)</TT> in
|
|
|
|
|
there - and when they hit return or tab the value updates to
|
|
|
|
|
what they typed and the callback is done.
|
|
|
|
|
|
2006-03-29 18:54:39 +04:00
|
|
|
<P>If <TT>step()</TT> is non-zero and integral, then the range of numbers
|
|
|
|
|
is limited to integers instead of floating point numbers. As
|
|
|
|
|
well as displaying the value as an integer, typed input is also
|
|
|
|
|
limited to integer values, even if the hidden <TT>Fl_Input</TT> widget
|
|
|
|
|
is of <TT>type(FL_FLOAT_INPUT)</TT>.</P>
|
|
|
|
|
|
2002-05-25 16:17:18 +04:00
|
|
|
<P>If <TT>step()</TT> is non-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 right button by <TT>100 * step()</TT>. It
|
|
|
|
|
is therefore impossible to select text by dragging across it,
|
|
|
|
|
although clicking can still move the insertion cursor.</P>
|
|
|
|
|
|
|
|
|

<P>If <TT>step()</TT> is non-zero and integral, then the range
|
|
|

|
of numbers are limited to integers instead of floating point
|
|
|
|
|
values.
