Accessing combo box text

[deepak bhujangachar harvelsystems com]

Hi All,

I am using Glade 3.0 and GTKMM. I am trying to access Combo box text  
and id. I am failing in it. I pasted a code I did. Please help in  
accessing Combo box attributes.

//This is the signal

if(m_Combo1)
{
   m_Combo1->signal_changed().connect( sigc::mem_fun(*this,  
&mainWindow::combo_product_changed));
}

//Trying to access ID

void mainWindow::combo_product_changed()
{
  int product = m_Combo1->get_active_row_number();
  std::cout << "Row = " << product << std::endl;
}

Thanks
Deepak
