class Gtk::NumericSorter

Overview

Gtk::NumericSorter is a Gtk::Sorter that compares numbers.

To obtain the numbers to compare, this sorter evaluates a Gtk::Expression.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/numeric_sorter.cr

Constructor Detail

def self.new(expression : Gtk::Expression | Nil) : self #

Creates a new numeric sorter using the given expression.

Smaller numbers will be sorted first. You can call Gtk::NumericSorter#sort_order= to change this.


[View source]
def self.new #

Initialize a new NumericSorter.


[View source]
def self.new(*, expression : Gtk::Expression | Nil = nil, sort_order : Gtk::SortType | Nil = nil) #

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def expression : Gtk::Expression | Nil #

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


[View source]
def expression=(expression : Gtk::Expression | Nil) : Nil #

Sets the expression that is evaluated to obtain numbers from items.

Unless an expression is set on self, the sorter will always compare items as invalid.

The expression must have a return type that can be compared numerically, such as %G_TYPE_INT or %G_TYPE_DOUBLE.

def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def sort_order : Gtk::SortType #

Gets whether this sorter will sort smaller numbers first.


[View source]
def sort_order=(sort_order : Gtk::SortType) : Nil #

Sets whether to sort smaller numbers before larger ones.
