<H3>Description</H3>
|
|
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>

<H4><A name=Fl_Slider.type>uchar Fl_Widget::type() const

|
Setting this changes how the slider is drawn, which can be one of the
|
|
following:
|
|
<UL>
|
|
<LI><TT>FL_VERTICAL</TT> - Draws a vertical slider (this is the
|
|
default). </LI>
|
|
<LI><TT>FL_HORIZONTAL</TT> - Draws a horizontal slider. </LI>
|
|
<LI><TT>FL_VERT_FILL_SLIDER</TT> - Draws a filled vertical slider,
|
|
useful as a progress or value meter. </LI>
|
|
<LI><TT>FL_HOR_FILL_SLIDER</TT> - Draws a filled horizontal slider,
|
|
useful as a progress or value meter. </LI>
|
|
<LI><TT>FL_VERT_NICE_SLIDER</TT> - Draws a vertical slider with a nice
|
|
looking control knob. </LI>
|
|
<LI><TT>FL_HOR_NICE_SLIDER</TT> - Draws a horizontal slider with a
