Sort by comparing numbers.
Gtk::NumericSorter is a Gtk::Sorter that compares numbers.
To obtain the numbers to compare, this sorter evaluates a Gtk::Expression.

| Glib::RefPtr< Expression< T > > Gtk::NumericSorter< T >::get_expression | ( | ) | 
Gets the expression that is evaluated to obtain numbers from items.
nullptr. | Glib::RefPtr< const Expression< T > > Gtk::NumericSorter< T >::get_expression | ( | ) | const | 
Gets the expression that is evaluated to obtain numbers from items.
nullptr.    | Glib::PropertyProxy< Glib::RefPtr< Expression< T > > > Gtk::NumericSorter< T >::property_expression | ( | ) | 
The expression to evalute on items to get a number to compare with.
| Glib::PropertyProxy_ReadOnly< Glib::RefPtr< Expression< T > > > Gtk::NumericSorter< T >::property_expression | ( | ) | const | 
The expression to evalute on items to get a number to compare with.
| void Gtk::NumericSorter< T >::set_expression | ( | const Glib::RefPtr< Expression< T > > & | expression | ) | 
Sets the expression that is evaluated to obtain numbers from items.
Unless an expression is set on the Gtk::NumericSorter, the sorter will always compare items as invalid.
The expression must have a return type that can be compared numerically, such as int or double.
| expression | A Gtk::Expression, or nullptr. |
