Gtk.Try_Expression

Description

A GtkExpression that tries to evaluate each of its expressions until it succeeds.

If all expressions fail to evaluate, the GtkTryExpression's evaluation fails as well.

Create

function Create
   (Object : not null access System.Address)
    return Gtk_Try_Expression_Record

Parameters

Object

Return Value

Get_Type

function Get_Type return Glib.GType

Return Value

Gtk_New

procedure Gtk_New
  (Self        : out Gtk_Try_Expression;
   Expressions : Gtk.Expression.Gtk_Expression_Array)

Creates a GtkExpression with an array of expressions. When evaluated, the GtkTryExpression tries to evaluate each of its expressions until it succeeds. If all expressions fail to evaluate, the GtkTryExpression's evaluation fails as well. The value type of the expressions in the array must match. Since: gtk+ 4.22 Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Expressions

The array of expressions

Gtk_Try_Expression

type Gtk_Try_Expression is access all Gtk_Try_Expression_Record'Class;

Gtk_Try_Expression_Record

type Gtk_Try_Expression_Record is new Gtk_Expression_Record with null record;

Initialize

procedure Initialize
  (Self        : not null access Gtk_Try_Expression_Record'Class;
   Expressions : Gtk.Expression.Gtk_Expression_Array)

Creates a GtkExpression with an array of expressions. When evaluated, the GtkTryExpression tries to evaluate each of its expressions until it succeeds. If all expressions fail to evaluate, the GtkTryExpression's evaluation fails as well. The value type of the expressions in the array must match. Since: gtk+ 4.22 Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

The array of expressions
