|
|
|
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
|
2001-10-01 00:25:36 +04:00
|
|
|
hidden <A href=Fl_Input.html#Fl_Input><TT>Fl_Input</TT></A> widget with <TT>
|
2001-11-29 22:24:00 +03:00
|
|
|
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
|
1999-01-13 22:28:54 +03:00
|
|
|
across the object and thus slide the value. The left button moves one <TT>
|
2001-11-29 22:24:00 +03:00

|
|
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. </P>
