Re: Gtk::TreeModel::ColumnsRecord's children

["Paul Davis" <pjdavis engineering uiowa edu>]

Sergio,

Do you mean, how do you get to the rows in a TreeStore or ListStore?

I think the function you're looking for is Gtk::TreeModel::children()

TreeStore and ListStore both implement this method. The following is a
recusive method to visit all rows in a TreeStore.  The linear
ListStore should be a simple case to extract.

Assume _store is a Glib::RefPtr< Gtk::TreeStore > type member variable of Foo.

void
Foo::go()
{
	traverse( _store->children() ) ;
}

void
Foo::traverse( Gtk::TreeModel::Children children )
{
	if( children.empty() )
	{
		return ;
	}

	Gtk::TreeModel::Children::iterator iter ;

	for( iter = children.begin() ; iter != children.end() ; iter++ )
	{
		traverse( (*iter)->children() ) ;
	}
}
