[controlP5] Help with setValue()

in Contributed Library Questions • 3 years ago

I have searched the forums and didn't quite find the answer. I am new to processing and controlP5 so sorry for the simple question.

I am trying to add text field and have it update the time. I can't seem to get the controlP5 library to update the text field. below is my code. Thanks in advance.

import java.nio.ByteBuffer;
import processing.serial.*;
import controlP5.*;

float TimeInMs;
float TimeInMinutes;
float TimeInHours;

Serial myPort;

ControlP5 controlP5;
controlP5.Textfield Time_ET;

PFont AxisFont, TitleFont;

void setup()
{
frameRate(30);
size(400, 400);

println(Serial.list());
myPort = new Serial(this, Serial.list()[0], 9600);

controlP5 = new ControlP5(this);
controlP5.setColorBackground(50);
controlP5.setColorLabel(0);

Time_ET = controlP5.addTextfield("Time",200,200,60,20);

}

void draw()
{
background(200);
TimeInMs=millis();
TimeInMinutes=TimeInMs/60000;
TimeInHours=TimeInMs/3600000;
Time_ET.setValue(TimeInMinutes);
}

If you want to change the value of a controlP5 controller use something like this...

controlP5.controller("Time_ET").setValue(TimeInMinutes);

However, I think controlP5's textfield is an input field. It seems you just want to display text on the screen.

In that case it's easier to use Processing's text functions. Take a look at some of the examples included with the program.

Also note that what you are doing is the time counting from the start of the program, not the general time. If you want the latter, you can use the hour(), minute(), second() functions.

I think with a Textfield you want to use the setText() method instead of setValue().

(Be sure to convert the float to a string first.)
