(ERROR HELP) pushButton was not declared in this scope.

Hello,

I am a newbie in QT. I tried making a browse button to display file dialog but on complie time it gives an error:

"pushButton was not declared in this scope"

I have included the appropriate headers.

Here is the header:

Code:

---

#ifndef PT_H
#define PT_H
 
#include <QWidget>
#include<QPushButton>
#include "pt.h"
 
namespace Ui {
    class pt;
}
 
class pt : public QWidget {
    Q_OBJECT
public:
    pt(QWidget *parent = 0);
    ~pt();
 
public slots:
    void browse();
 
protected:
    void changeEvent(QEvent *e);
 
private:
    Ui::pt *ui;
};
 
#endif // PT_H

---

Here is main.cpp

Code:

---

#include <QtGui/QApplication>
#include<QtGui/QPushButton>
#include<QFileDialog>
#include "pt.h"
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    pt w;
    w.show();
    return a.exec();
}

---

and finally the pt.cpp (pt my project name :))

Code:

---

#include<QtGui/QApplication>
#include<QFileDialog>
#include<QtGui>
#include<QtGui/QPushButton>
#include "pt.h"
#include "ui_pt.h"
 
pt::pt(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::pt)
{
    ui->setupUi(this);
 
    connect( pushButton, SIGNAL( clicked() ), this, SLOT( browse() ) );
}
 
pt::~pt()
{
    delete ui;
}
 
void pt::browse()
{
    QString path;
 
    path = QFileDialog::getOpenFileName(
        this,
        "Choose a file to open",
        QString::null,
        QString::null);
 
    ui->lineEdit->setText( path );
}
 
void pt::changeEvent(QEvent *e)
{
    QWidget::changeEvent(e);
    switch (e->type()) {
    case QEvent::LanguageChange:
        ui->retranslateUi(this);
        break;
    default:
        break;
    }
}

Somebody please help me on this !!

    Q_OBJECT
public:
    pt(QWidget *parent = 0);
    ~pt();
 
public slots:
    void browse();
 
protected:
    void changeEvent(QEvent *e);
 
private:
    Ui::pt *ui;
};
 
#endif // PT_H

main.cpp

    ui(new Ui::pt)
{
    ui->setupUi(this);
 
   // connect( pushButton, SIGNAL( clicked() ), this, SLOT( browse() ) );
    connect( ui->pushButton, SIGNAL( clicked() ), this, SLOT( browse() ) );
}
 
pt::~pt()
{
    delete ui;
}
 
void pt::browse()
{
    QString path;
 
    path = QFileDialog::getOpenFileName(
        this,
        "Choose a file to open",
        QString::null,
        QString::null);
 
    ui->lineEdit->setText( path );
}
 
void pt::changeEvent(QEvent *e)
{
    QWidget::changeEvent(e);
    switch (e->type()) {
    case QEvent::LanguageChange:
        ui->retranslateUi(this);
        break;
    default:
        break;
    }
}
