Custom signal and slots

[amitahire]

Hello again,


I am trying to make a simple application where when I click a button the count is displayed in the QLineEdit. But I cant get the signal going. I have read different documentations but for custom signal and slots everywhere I see I get a different account or method.

I am posting my files. Please help me understand the concept

click.h

#ifndef CLICK_H
#define CLICK_H
 
#include<QMainWindow>
#include<QLineEdit>
#include<QPushButton>
 
namespace Ui
{
   class click_me;
}
 
 
class click_me:public QMainWindow
{
   Q_OBJECT
public:
   click_me(QWidget *Parent=0);
signals:
    void click1(int);
private slots:
    void disp();
private:
  Ui::click_me *ui;
private:
  QPushButton *p1;
  QLineEdit *l1;
};
#endif

#ifndef CLICK_H
#define CLICK_H

#include<QMainWindow>
#include<QLineEdit>
#include<QPushButton>

namespace Ui
{
   class click_me;
}


class click_me:public QMainWindow
{
   Q_OBJECT
public:
   click_me(QWidget *Parent=0);
signals:
    void click1(int);
private slots:
    void disp();
private:
  Ui::click_me *ui;
private:
  QPushButton *p1;
  QLineEdit *l1;
};
#endif

I am just unable to understand how do I pass parameters in the signal and even if I am passing one.... How do I go about declaring, defining and passing them.

Clearing its a off day for me :-\
