[quote author="IamSumit" date="1412144476"]Hi .
Can you show me your full code (including .h)?
and tell me what errors you are getting also?

@#include "dialog.h"
#include "ui_dialog.h"
#include <QMovie>
#include <QImage>
#include <QFontDatabase>
#include <QDebug>
#include <QKeyEvent>

Dialog::Dialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog)
{
ui->setupUi(this);
}

Dialog::~Dialog()
{
delete ui;
}

void ShowPicture(QString path)
{
QMovie *movie = new QMovie(path);
QLabel *processLabel = new QLabel(this);
ui->processLabel->setMovie(movie);
movie->start();

            ui->label1->setText(QString::fromUtf8("chennai  சென்னை"));
            ui->label1->show();

}

void Dialog::keyPressEvent(QKeyEvent *e)
{

if(e->key() == Qt::Key_F3)
{
        ShowPicture(”/home/dev6/Desktop/animation/2.gif”);
}

}@

IamSumit

ok.
ShowPicture(QString) is the member function/method of Dialog class.
i can't see proper definition of this method.
in line 21.
@
Replace void Dialog::ShowPicture(QString path)
@

and in .h file declare this method as member.
in .h file. add this line
@
public:
void ShowPicture(QString path);
@

and your oops basics are not clear.So, Please improve your basics first.

Hope it helps.

Hi.
You are not passing a string .string always encloses " " quotes.
@
19.ShowPicture(/home/dev6/Desktop/animation/2.gif);
@
Correct it as .
ShowPicture("/home/dev6/Desktop/animation/2.gif");
