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.
|
protected |
|
static |
| 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. |
