I also want to do the same thing and I have approached to implement this thing is, I subclass the QComboBox and add some my custom slot and signal.
header file

#ifndef _MY_COMBO_BOX_H
#define _MY_COMBO_BOX_H
 
#include <qobject.h>
#include <qcombobox.h>
 
//***********Defination of OdyComboBox****************
 
class CMyComboBox : public QComboBox
{
	Q_OBJECT
 
public:
    CMyComboBox ( int row, int column, QWidget * parent, const char * name = 0 ) ;
 
signals:
	void activated (int row, int column, const QString & string);
 
public slots:
    void reEmitActivated(const QString &);
 
private:
    int row;
    int column;
};
 
#endif

#ifndef _MY_COMBO_BOX_H
#define _MY_COMBO_BOX_H

#include <qobject.h>
#include <qcombobox.h>

//***********Defination of OdyComboBox****************

class CMyComboBox : public QComboBox
{
	Q_OBJECT
    
public:
    CMyComboBox ( int row, int column, QWidget * parent, const char * name = 0 ) ;
    
signals:
	void activated (int row, int column, const QString & string);
    
public slots:
    void reEmitActivated(const QString &);
    
private:
    int row;
    int column;
};

#endif

hi sumsin,
ur implementation was nice .... i got a bit confused in the code :

CMyComboBox::CMyComboBox (int row, int column, QWidget * parent, const char * name )
  : QComboBox( parent, name ), row(row), column(column)

CMyComboBox::CMyComboBox (int row, int column, QWidget * parent, const char * name )
  : QComboBox( parent, name ), row(row), column(column)

To copy to clipboard, switch view to plain text mode 

u inherited QComboBox, now in the constructor, what the lines row(row),column(column) mean?

void CMyComboBox::reEmitActivated(const QString & string) {
  emit activated( row, column, string );
}

void CMyComboBox::reEmitActivated(const QString & string) {
  emit activated( row, column, string );
}

To copy to clipboard, switch view to plain text mode 

here how u got the row and column ?

i am a new user to this ..... so if its too easy, then also pls reply ....

This is NOT inside QComboBox's constructor. Row and Column are getting initialized.

here how u got the row and column ?

row and column are member variables of CMyComboBox.

Exactly. What munna says.
Thanks munna.
