not a class, namespace, or enumeration??

[splashfreeze]

So I have a class defined in a header file like so...

#ifndef TIMER_H
#define TIMER_H
#include <QObject>
class Timer : public QObject
{
    Q_OBJECT
    public slots:
    void StartTimer();
signals:
    void TimeOut();
};
#endif // TIMER_H

#ifndef TIMER_H
#define TIMER_H
#include <QObject>
class Timer : public QObject
{
    Q_OBJECT
    public slots:
    void StartTimer();
signals:
    void TimeOut();
};
#endif // TIMER_H

To copy to clipboard, switch view to plain text mode 

and what my main function does is simply create an instance of the timer class and make a connect with a signal from
a textedit object

Below is the main function

#include "window.h"
#include <QApplication>
#include "timer.h"
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    window w;
    Timer t;   
    t::connect(w, SIGNAL(w::on_textEdit_textChanged()),t,SLOT(t::StartTimer()));   
    w.show();
    return a.exec();
}

#include "window.h"
#include <QApplication>
#include "timer.h"
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    window w;
    Timer t;   
    t::connect(w, SIGNAL(w::on_textEdit_textChanged()),t,SLOT(t::StartTimer()));   
    w.show();
    return a.exec();
}

So can anyone explain why I get the error message "'t' is not a class, namespace or enumeration"?
