Two questions

[Konstantin L Kouptsov <klk206 panix com>]

In my program I would like to have a ListStore/TreeView list with 
several columns, to which I will add additional rows. I also want that 
each time the row is added, the (re)calculation over entire list is 
performed, say, using on_row_added(). For the last thing, I need to 
catch some event and connect it to my on_row_added() function.

1. To add a row I have the code as follows:

// these are defined elsewhere

 class StimListRow:public Gtk::TreeModel::ColumnRecord
	{ ... } glr,slr;
 Glib::RefPtr<Gtk::ListStore> good_ref= Gtk::ListStore::create(glr);
 Gtk::TreeView *treeview;

// now the code:

 Glib::RefPtr<Gtk::TreeSelection> Selection = treeview->get_selection();
 Gtk::ListStore::iterator iter = Selection->get_selected();

 treeview->remove_all_columns();
 Gtk::ListStore::Row new_row = *(good_ref->append());
 int time = row[slr.time];
 int chan = row[slr.chan];
 new_row[glr.time] = time;
 new_row[glr.chan] = chan;
 treeview->set_model(good_ref);
 treeview->append_column("Stim", glr.time);
 treeview->append_column("Channel", glr.chan);

This works, but I am not sure this is the best way. Is there more 
elegant way of doing that?

Also, thinking about events to catch, what are the events that may be 
suitable for my task (i.e. to call recalculate() once after the row was 
added)


2. When trying to add event handler to solve the previous task, I get an 
error when adding the following line

good_ref->signal_row_inserted().connect(SigC::slot(*this,&MyWindow::on_row_added),false);



MyWindow.cc: In member function `int TrigViewWindow::open_trg_file()':
MyWindow.cc:410: error: no matching function for call to `
   Glib::SignalProxy2<void, const Gtk::TreePath&, const Gtk::TreeIter&>::
   connect(SigC::Slot0<void>, bool)'
/usr/include/gtkmm-2.0/glibmm/signalproxy.h:159: error: candidates are:
   SigC::Connection Glib::SignalProxy2<R, P1, P2>::connect(const 
SigC::Slot2<R,
   P1, P2>&, bool) [with R = void, P1 = const Gtk::TreePath&, P2 = const
   Gtk::TreeIter&]

Can someone shed a light on what's going on?

I also use glade to design interface, and some of the events added by 
glade generate the same type of error. Perhaps I am missing something.

Any help?
