[SOLVED]QTimer queries

[praveen0991kr]

I am able to run Qtimer but have some basic doubts --

In mainwindow.c file
@
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QTimer>

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
UpdtScr = new QTimer();
UpdtScr->start(200);
connect(UpdtScr,SIGNAL(timeout()),this,SLOT(UpdtScrn()));
}

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

void MainWindow::UpdtScrn()
{
int i;
i++;
qDebug()<<i;
}

@

In mainwindow.h file

@
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QTimer>

namespace Ui {
class MainWindow;
}

class QTimer;
class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

QTimer *UpdtScr;

public slots:
void UpdtScrn();

private:
Ui::MainWindow *ui;

};
#endif // MAINWINDOW_H

@

In mainwindow.h I have declare;

@
QTimer *UpdtScr;
@
Could I declare @QTimer UpdtScr; @
so what will be declaration in mainwindow .c
@
UpdtScr = new QTimer();
//It not working ;
connect(UpdtScr,SIGNAL(timeout()),this,SLOT(UpdtScrn()));
//Is also having some problem pls.
@

Pls clearify I will be thankful to you
