#include "widget.h"
#include "ui_widget.h"
 
#include <QPainter>
 
Widget::Widget(QWidget *parent)
    : QWidget(parent), 
	ui(new Ui::WidgetClass),
	m_currentImage(0)
{
    ui->setupUi(this);
 
        ui->label->setPixmap(QPixmap("C:/Documents and Settings/addu.YUVARAJ.001/Desktop/yuvaraj.png"));
        ui->pushButton->hide();
        ui->toolButton->hide();

         ui->label->installEventFilter(this);
}
 
Widget::~Widget()
{
    delete ui;
}
 
bool Widget::eventFilter(QObject *o, QEvent *e)
{
  if (o == ui->label && e->type() == QEvent::MouseMove)
    {
 
 
         QPixmap pixmap(QString("C:/Documents and Settings/addu.YUVARAJ.001/Desktop/yuvaraj.png"));
 
        ui->label->setPixmap(pixmap);
        ui->pushButton->show();
        ui->toolButton->show();
        ui->pushButton_2->show();
        ui->toolButton_2->show();
        ui->toolButton->setIcon(QIcon("C:/Documents and Settings/addu.YUVARAJ.001/Desktop/raj.png"));
        ui->pushButton->setIcon(QIcon("C:/Documents and Settings/addu.YUVARAJ.001/Desktop/raj.png"));
        ui->toolButton_2->setIcon(QIcon("C:/Documents and Settings/addu.YUVARAJ.001/Desktop/raj.png"));
        ui->pushButton_2->setIcon(QIcon("C:/Documents and Settings/addu.YUVARAJ.001/Desktop/raj.png"));
        return true;
    }
 
   else
  {
 
 
	return QWidget::eventFilter(o, e);
  }
}
 
void Widget::on_pushButton_clicked()
{
    this-close();
}
