Processing code for emulating arrow keys :

Processing code for Scroll bar :


PFont logFont;
Scrollbar bar;
String content = "";
float scrollbarRatio;
String absolutePath;
int line;

void setup()
{
  size(1080, 700);
  logFont = loadFont("CenturyGothic-16.vlw");

  bar = new Scrollbar(width-20, 85, 20, 250, 1);
  setLogPath();
}
void draw()
{

  drawLogContent();

}
void setLogPath()
{
  absolutePath = "data/new.txt";  //selection.getAbsolutePath();
  String lines[] = loadStrings(absolutePath);
  content = "";
  line = 0;

  for (int i = 0; i < lines.length; i++) {
    String lineContent = lines[i] + "\n";
    content += lineContent;
    line++;
  }
}




void drawLogContent()
{
  String[] adjustedLines = content.split("\n");

  int maxLines = 19;//floor((height - 10) / 42);

  if (adjustedLines.length > maxLines)
  {
    scrollbarRatio = ((float) maxLines) / ((float) adjustedLines.length);
  }

  // Text Box
  //fill(80);
  //rect(0, 0, width, height);

  textAlign(LEFT);
  textLeading(25);
  fill(225);

  //String[] contentLines = content.split("\n");
  String display = "";

  int lineDifference = bar.getLineDifference();

  if (adjustedLines.length > maxLines)
  {
    for (int i = lineDifference; i < maxLines + lineDifference; i++)
    {
      if (i < adjustedLines.length)
      {
        display += adjustedLines[i];
        display += "\n";
      }
    }
  } else
  {
    display = content;
  }
  noStroke();
  fill(0);
  rect(653, 70, 425, 415);
  textFont(logFont);
  fill(70, 233, 22);
  text("Log display", 830, 95);
  text(display, 660, 125);
  fill(240);
  bar.resizeScrollbar(width-20, 85, 20, 250);
  bar.update(scrollbarRatio);
  bar.display(scrollbarRatio);
