changing clock/date setting on Real Time Clock pcf8563 [solved]

Using Arduino Programming Questions

I have an lcd and a Pcf8563 Real Time Clock. I have the following sketch which is used to set the time and date.

/* Demonstration of Rtc_Pcf8563 Clock on LCD. 
 *
 * I used a Arduino mega 2560,
 * SCL -21, SDA - 20,
 *
 * This sketch connects a lcd to display the clock output.

#include <Wire.h>
#include <Rtc_Pcf8563.h>
/* add the lcd support */ 
#include <LiquidCrystal.h>

//init the real time clock
Rtc_Pcf8563 rtc;

/* initialize the library objects */

LiquidCrystal lcd(7,8,9,10,11,12);

void setup()
{
  // set up the LCD's number of rows and columns: 
  lcd.begin(16, 2);
  
  //clear out all the registers
  rtc.initClock();
  //set a time to start with.
  //day, weekday, month, century, year
  rtc.setDate(14, 6, 3, 0, 10);
  //hr, min, sec
  rtc.setTime(1, 15, 40);
}

void loop()
{
  // set the cursor to column 0, line 1
  // (note: line 1 is the second row, since counting begins with 0):
  lcd.setCursor(0, 0);
  //lcd.print(rtc.formatTime(RTCC_TIME_HM));
  lcd.print(rtc.formatTime());
  lcd.setCursor(0, 1);
  //lcd.print(rtc.formatDate(RTCC_DATE_ASIA));
  lcd.print(rtc.formatDate());
  
  delay(1000);
    
}

The sketch allows for the time and date to be set before the sketch is compliled. But I want to SET both using push buttons to change time and date variables.
The Libray for this "Rtc_Pcf8563.h", has the code for changing the time and date. So would the answer lie in the library. Do I cut and past the code from the libray into the sketch above .
