如题
代码如下
import controlP5.*;
ControlP5 cp5;
int myColor = color(0,0,0);
int sliderValue = 100;
int sliderTicks1 = 100;
int sliderTicks2 = 30;
Slider abc;
void setup() {
size(700,400);
noStroke();
cp5 = new ControlP5(this);
// add a horizontal sliders, the value of this slider will be linked
// to variable ‘sliderValue’
cp5.addSlider(“sliderValue”)
.setPosition(100,50)
.setRange(0,255)
;
// create another slider with tick marks, now without
// default value, the initial value will be set according to
// the value of variable sliderTicks2 then.
cp5.addSlider(“sliderTicks1”)
.setPosition(100,140)
.setSize(20,100)
.setRange(0,255)
.setNumberOfTickMarks(5)
;
// add a vertical slider
cp5.addSlider(“slider”)
.setPosition(100,305)
.setSize(200,20)
.setRange(0,200)
.setValue(128)
;
// reposition the Label for controller ‘slider’
cp5.getController(“slider”).getValueLabel().align(ControlP5.LEFT, ControlP5.BOTTOM_OUTSIDE).setPaddingX(0);
cp5.getController(“slider”).getCaptionLabel().align(ControlP5.RIGHT, ControlP5.BOTTOM_OUTSIDE).setPaddingX(0);
cp5.addSlider(“sliderTicks2”)
.setPosition(100,370)
.setWidth(400)
.setRange(255,0) // values can range from big to small as well
.setValue(128)
.setNumberOfTickMarks(7)
.setSliderMode(Slider.FLEXIBLE)
;
// use Slider.FIX or Slider.FLEXIBLE to change the slider handle
// by default it is Slider.FIX
}
void draw() {
background(sliderTicks1);
