This solution brings another error.

	std::list<QueryTab *> m_Tabs;

	QueryTab *d_tab = new QueryTab();
	for(std::list<QueryTab *>::iterator i_Tabs = m_Tabs.begin(); i_Tabs !=
m_Tabs.end(); i_Tabs++)
	{
		m_Tabs.push_back(*i_Tabs);
		m_Notebook.append_page(*i_Tabs);
	}

Error	1	error C2664: 'int Gtk::Notebook::append_page(Gtk::Widget &)' :
cannot convert parameter 1 from 'QueryTab *' to 'Gtk::Widget &'
d:\documents\visual studio 2008\projects\db2client\db2client\mainwindow.cpp
21	db2client

How am i supposed to add d_tab to m_Notebook?
