2.4" TFT LCD coding problem.

Using Arduino Displays
1

I had bought a 2.4" TFT touchscreen LCD like this :

Below is the ode i am using,

#include <UTFT.h>
#include <UTouch.h>

// Initialize display
// ------------------

UTFT    myGLCD(ITDB32S,19,18,17,16);


UTouch  myTouch( 15,10,14,9,8)

// Declare which fonts we will be using
extern uint8_t BigFont[];

int color = 0;
word colorlist[] = {VGA_WHITE, VGA_BLACK, VGA_RED, VGA_BLUE, VGA_GREEN, VGA_FUCHSIA, VGA_YELLOW, VGA_AQUA};
int  bsize = 4;

void drawColorMarkerAndBrushSize(int col)
{
  myGLCD.setColor(VGA_BLACK);
  myGLCD.fillRect(25, 0, 31, 239);
  myGLCD.fillRect(myGLCD.getDisplayXSize()-31, 161, myGLCD.getDisplayXSize()-1, 191);
  myGLCD.setColor(VGA_WHITE);
  myGLCD.drawPixel(25, (col*30)+15);
  for (int i=1; i<7; i++)
    myGLCD.drawLine(25+i, ((col*30)+15)-i, 25+i, ((col*30)+15)+i);
  
  if (color==1)
    myGLCD.setColor(VGA_WHITE);
  else
    myGLCD.setColor(colorlist[col]);
  if (bsize==1)
    myGLCD.drawPixel(myGLCD.getDisplayXSize()-15, 177);
  else
    myGLCD.fillCircle(myGLCD.getDisplayXSize()-15, 177, bsize);
    
  myGLCD.setColor(colorlist[col]);
}

void setup()
{
  myGLCD.InitLCD();
  myGLCD.clrScr();
  myGLCD.setFont(BigFont);

  myTouch.InitTouch();
  myTouch.setPrecision(PREC_HI);
  
  myGLCD.setColor(VGA_WHITE);
  myGLCD.drawLine(32,0,32,myGLCD.getDisplayYSize()-1);
  myGLCD.drawLine(myGLCD.getDisplayXSize()-32,0,myGLCD.getDisplayXSize()-32,myGLCD.getDisplayYSize()-1);
  myGLCD.print("C", myGLCD.getDisplayXSize()-24, 8);
  myGLCD.print("L", myGLCD.getDisplayXSize()-24, 24);
  myGLCD.print("E", myGLCD.getDisplayXSize()-24, 40);
  myGLCD.print("A", myGLCD.getDisplayXSize()-24, 56);
  myGLCD.print("R", myGLCD.getDisplayXSize()-24, 72);
  myGLCD.print("+", myGLCD.getDisplayXSize()-24, 136);
  myGLCD.print("-", myGLCD.getDisplayXSize()-24, 200);
  myGLCD.fillRect(myGLCD.getDisplayXSize()-32,96,myGLCD.getDisplayXSize()-1,128);
  myGLCD.drawLine(myGLCD.getDisplayXSize()-32,160,myGLCD.getDisplayXSize()-1,160);
  myGLCD.drawLine(myGLCD.getDisplayXSize()-32,192,myGLCD.getDisplayXSize()-1,192);
  myGLCD.drawLine(myGLCD.getDisplayXSize()-32,224,myGLCD.getDisplayXSize()-1,224);
  for (int i=0; i<8; i++)
  {
    myGLCD.setColor(colorlist[i]);
    myGLCD.fillRect(0, (i*30), 24, (((i+1)*30)-1));
  }
  drawColorMarkerAndBrushSize(color);
}

void loop()
{
  long x, y;
  
  while (myTouch.dataAvailable() == true)
  {
    myTouch.read();
    x = myTouch.getX();
    y = myTouch.getY();
    if ((x!=-1) and (y!=-1))
    {
      if (x>(31+bsize) and (x<myGLCD.getDisplayXSize()-(31+bsize)))
      {
        if (bsize==1)
          myGLCD.drawPixel(x, y);
        else
          myGLCD.fillCircle(x, y, bsize);
      }
      else
      {
        if (x<(30+bsize))
        {
          if (y<240)
          {
            color = y / 30;
            drawColorMarkerAndBrushSize(color);
            while (myTouch.dataAvailable()) {};
            delay(50);
         }
        }
        else
        {
          if (y<96)
          {
            myGLCD.setColor(VGA_BLACK);
            myGLCD.fillRect(33, 0, myGLCD.getDisplayXSize()-33, myGLCD.getDisplayYSize()-1);
            myGLCD.setColor(colorlist[color]);
          }
          if ((y>128) and (y<160))
          {
            if (bsize<7)
            {
              bsize++;
              drawColorMarkerAndBrushSize(color);
              while (myTouch.dataAvailable()) {};
              delay(50);
            }
          }
          if ((y>160) and (y<192))
          {
              bsize=4;
              drawColorMarkerAndBrushSize(color);
              while (myTouch.dataAvailable()) {};
              delay(50);
          }
          if ((y>192) and (y<224))
          {
            if (bsize>1)
            {
              bsize--;
              drawColorMarkerAndBrushSize(color);
              while (myTouch.dataAvailable()) {};
              delay(50);
            }
          }
        }
      }
    }
  }
}

i had imported the related libraries however there is some errors as shown:

UTouch_QuickPaint:28: error: 'UTFT' does not name a type
UTouch_QuickPaint:40: error: 'UTouch' does not name a type
UTouch_QuickPaint:46: error: 'VGA_WHITE' was not declared in this scope

Can someone help me with it??
I am using Arduino Uno for this project. Thanks

Errors like that usually mean that either you didn't restart the IDE after installing the libraries or you installed them in the wrong place.
