Re: Gtk::TreeSelection::get_selected_rows()

[Doug McLain <dougmclain cayf org>]

I sort of combined both of your examples to get an error free build:

vector<Gtk::TreeModel::Path> pathlist = 
redirect_display.get_selection()->get_selected_rows();
	
for (vector<Gtk::TreeModel::Path>::iterator iter = pathlist.begin(); 
iter != pathlist.end(); ++iter) {
		TreeModel::Row row = *(model->get_iter (*iter));
		redirects.push_back (row[columns.redirect]);
	}
