Gtk.Numeric_Sorter

Description

Sorts items numerically.

To obtain the numbers to compare, this sorter evaluates a [classGtk.Expression].

Get_Expression

function Get_Expression
   (Self : not null access Gtk_Numeric_Sorter_Record)
    return Gtk.Expression.Gtk_Expression

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

Parameters

Self

Return Value

a GtkExpression. Has transfer-ownership='none'.

Get_Sort_Order

function Get_Sort_Order
   (Self : not null access Gtk_Numeric_Sorter_Record)
    return Gtk.Enums.Gtk_Sort_Type

Gets whether this sorter will sort smaller numbers first.

Parameters

Self

Return Value

the order of the numbers

Get_Type

function Get_Type return Glib.GType

Return Value

Gtk_New

procedure Gtk_New
   (Self       : out Gtk_Numeric_Sorter;
    Expression : Gtk.Expression.Gtk_Expression)

Creates a new numeric sorter using the given Expression. Smaller numbers will be sorted first. You can call [methodGtk.NumericSorter.set_sort_order] to change this. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Expression

The expression to evaluate. Has transfer-ownership='full'.

Gtk_Numeric_Sorter

type Gtk_Numeric_Sorter is access all Gtk_Numeric_Sorter_Record'Class;

Gtk_Numeric_Sorter_New

function Gtk_Numeric_Sorter_New
   (Expression : Gtk.Expression.Gtk_Expression) return Gtk_Numeric_Sorter

Creates a new numeric sorter using the given Expression. Smaller numbers will be sorted first. You can call [methodGtk.NumericSorter.set_sort_order] to change this.

Parameters

Expression

The expression to evaluate. Has transfer-ownership='full'.

Return Value

Gtk_Numeric_Sorter_Record

type Gtk_Numeric_Sorter_Record is new Gtk_Sorter_Record with null record;

Initialize

procedure Initialize
   (Self       : not null access Gtk_Numeric_Sorter_Record'Class;
    Expression : Gtk.Expression.Gtk_Expression)

Creates a new numeric sorter using the given Expression. Smaller numbers will be sorted first. You can call [methodGtk.NumericSorter.set_sort_order] to change this. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Expression

The expression to evaluate. Has transfer-ownership='full'.

Set_Expression

procedure Set_Expression
   (Self       : not null access Gtk_Numeric_Sorter_Record;
    Expression : Gtk.Expression.Gtk_Expression)

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.

Parameters

Self

Expression

a GtkExpression

Set_Sort_Order

procedure Set_Sort_Order
   (Self       : not null access Gtk_Numeric_Sorter_Record;
    Sort_Order : Gtk.Enums.Gtk_Sort_Type)

Sets whether to sort smaller numbers before larger ones.

Parameters

Self

Sort_Order

whether to sort smaller numbers first

Sort_Order_Property

Sort_Order_Property : constant Gtk.Enums.Property_Gtk_Sort_Type;

Whether the sorter will sort smaller numbers first.
