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.

Gets the expression that is evaluated to obtain numbers from items.
nullptr

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.
