/** |
|
The Fl_Slider 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 minimum(), and to the bottom/right to |
|
the maximum(). The minimum() may be greater than the |
|
maximum() to reverse the slider direction. |
|
|
|
<P>Use void Fl_Widget::type(int) to set how the slider is drawn, |
|
which can be one of the following: |
|
<UL> |
|
<LI>FL_VERTICAL - Draws a vertical slider (this is the |
|
default). </LI> |
|
<LI>FL_HORIZONTAL - Draws a horizontal slider. </LI> |
|
<LI>FL_VERT_FILL_SLIDER - Draws a filled vertical slider, |
|
useful as a progress or value meter. </LI> |
|
<LI>FL_HOR_FILL_SLIDER - Draws a filled horizontal slider, |
|
useful as a progress or value meter. </LI> |
|
<LI>FL_VERT_NICE_SLIDER - Draws a vertical slider with a nice |
|
looking control knob. </LI> |
|
<LI>FL_HOR_NICE_SLIDER - Draws a horizontal slider with a |
|
nice looking control knob. </LI> |
