Hi everyone!
I am using a ControlP5 ListBox to display a list of tweets which are written in italian. I can input a new query and the listbox should update showing the first 50 retrieved tweets.
Sometimes I get a warning like these:

No glyph found for the è (\u00E8) character

No glyph found for the ò (\u00F2) character

While some other times it just crashes because of the exception below. Does someone know how to solve this problem? Thanks in advance :)

Problem with Progress Bar

Hi guys!
I am using Processing (in particular Processing in Eclipse), but when I perform a time consuming task (for example loading many files), I don't know how to inform the user of the progress of the task. Let's suppose this simplified code: When a user clicks, a new loading is performed, FileLoader is a class I created to perform my file loading task, the problem is that, during the loading, the draw gets stuck, I would like to have something like: text("The progress is "+loader.getProgress(),width/2,height/2), I think this will involve threads or the Java class ProgressMonitor but I have never worked on this stuff, could someone please help me with a sample code? Thank you!

setup(){

}

draw(){

}

mousePressed(){

FileLoader loader = new FileLoader();

loader.performLoad(); //this method perform a loop of 3000 iterations, each one loads a file

}

Hi everyone!

I am using the code below to generate a PieChart, the problem is that I cannot use the noLoop() method because I have various elements in my sketch that are continuously updating, but removing noLoop causes the PieChart to start spinning without any apparent reason. Could someone help me in solving this problem?

Thank you so much.

float diameter;
int[] angles = { 30, 10, 45, 35, 60, 38, 75, 67 };
float lastAngle = 0;

void setup() {
  size(640, 360);
  background(100);
  noStroke();
  diameter = min(width, height) * 0.75;
  noLoop();  // Run once and stop
}


void draw() {
  for (int i = 0; i < angles.length; i++) {
    fill(angles[i] * 3.0);
    arc(width/2, height/2, diameter, diameter, lastAngle, lastAngle+radians(angles[i]));
    lastAngle += radians(angles[i]);
  }
}
