|
The <TT>Fl_Slider</TT> widget contains a sliding knob inside a box. It |
|
if often used as a scrollbar. Moving the box all the way to the |
|
top/left sets it to the <TT>minimum()</TT>, and to the bottom/right to |
|
the <TT>maximum()</TT>. The <TT>minimum()</TT> may be greater than the <TT> |
|
maximum()</TT> to reverse the slider direction. |

|
Set the type of box to draw for the moving part of the slider. The |
|
color of the moving part (or of the notch in it for the nice sliders) |
|
is controlled by <TT>selection_color()</TT>. The default value of zero |
|
causes the slider to figure out what to draw from <TT>box()</TT>. |
|
<H4><A name=Fl_Slider.slider_size>float Fl_Slider::slider_size() const |
|
<BR> void Fl_Slider::slider_size(float)</A></H4> |
|
Get or set the dimensions of the moving piece of slider. This is the |
|
fraction of the size of the entire widget. If you set this to 1 then |
|
the slider cannot move. The default value is .08. |
|
<P>For the "fill" sliders this is the size of the area around the end |
|
that causes a drag effect rather than causing the slider to jump to the |
|
mouse. </P> |
