Detailed Description
template<class T>
class Gtk::NumericSorter< T >
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.
- Returns
- A Gtk::Expression, or
nullptr
.
Glib::RefPtr<const Expression<T> > Gtk::NumericSorter< T >::get_expression | ( | ) | const |
Gets the expression that is evaluated to obtain numbers from items.
- Returns
- A Gtk::Expression, or
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.
- Returns
- A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.
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.
- Returns
- A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
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.
- Parameters
-
expression A Gtk::Expression, or nullptr
.
