<H3>Description</H3> |
|
The <TT>Fl_Value_Output</TT> widget displays a floating point value. |
|
If <TT>step()</TT> is not zero, the user can adjust the value by |
|
dragging the mouse left and right. 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>. |
|
<P>This is much lighter-weight than <A href=Fl_Value_Input.html#Fl_Value_Input> |
|
<TT>Fl_Value_Input</TT></A> because it contains no text editing code or |
|
character buffer. </P> |
