Here is the code from my textfinder.cpp

#include"textfinder.h"

#include  "ui_textfinder.h"

TextFinder::TextFinder(QWidget  *parent)  :

     QWidget(parent),

     ui(new  Ui::TextFinder)

{

     ui->setupUi(this);

}

TextFinder::~TextFinder()

{

     delete  ui;

}

void  TextFinder::on_findButton_clicked()

{

QString  searchString  =  ui->lineEdit->text();

ui->textEdit->find(searchString,QTextDocument::FindWholeWords);

}

void  TextFinder::loadTextFile()

{

     QFile  inputFile(":/input.txt");

     inputFile.open(QIODevice::ReadOnly);

     QTextStream  in(&inputFile);

     QString  line  =  in.readAll();

     inputFile.close();

     ui->textEdit->setPlainText(line);

     QTextCursor  cursor  =  ui->textEdit->textCursor();

     cursor.movePosition(QTextCursor::Start,QTextCursor::MoveAnchor,1);

}

Thanks

George
