Append directory path into textfield

SilentAce

I have the controlp5 textfield and a button. The button lets you select a folder and save a string path. How to i append the string to the textfield? Also i can get the list of subfolders from that directory. I managed to split them into a separate string array, however when i display them i get only the last one. How can i display all of them in a text(), but in a single strings? Here is the code.

import controlP5.*;

ControlP5 dirPath, dirButton;
String pathSelection = "";
String[] list = {};
File selection;
String path;
String[] dirSubfolders;
String[] singleFolder = {};

void setup(){
  size(600, 600, P3D);
  background(255);

  PFont font = createFont("Calibri-48.vwl", 20);

  dirPath = new ControlP5(this);
  dirButton = new ControlP5(this);  

  dirPath.addTextfield("input")
     .setPosition(20,20)
     .setSize(200,30)
     .setLabel("")
     .setAutoClear(false)
     .setFont(font)
     .setFocus(true)
     .setColor(color(255,0,0));

  //OpenDirectory is the button ID. setLabel gives the name to be viewed   
  dirButton.addButton("OpenDirectory")
     .setLabel("Open Directory")
     .setPosition(250,25)
     .updateSize();
}

void draw(){
  background(0);
  fill(255);
  // get the text from the input textfield and display it on x & y location
  // text(dirPath.get(Textfield.class, "input").getText(), 100, 100);

  if(singleFolder == null){ 
    println("empty");
  } else { 
    for(int i=0; i < singleFolder.length; i++){
      println(singleFolder[i]);
      text(singleFolder[i], 100, 100);
    }
  }
}

// Button event directory selection
void OpenDirectory() {
    println("Directory selection is pressed");
    selectFolder("Select a folder to process:", "setDirectoryPath");
}

void setDirectoryPath(File pathSelection){
  if(pathSelection == null) {
    println("Window was closed or the user hit cancel.");
  } else {
    println("Directory selected:  " + pathSelection.getAbsolutePath());
    // get the path to a string
    path = pathSelection.getAbsolutePath();

    // list the subfolders
    dirSubfolders = pathSelection.list();

    for(int i=0; i < dirSubfolders.length; i++){
      // get the single string folder names
      singleFolder = splitTokens(dirSubfolders[i], " ");
      //check
      //println(singleFolder);
    }
  }
}
