Gtk.Closure_Expression

Description

An expression using a custom GClosure to compute the value from its parameters.

Create

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

Parameters

Object

Return Value

Get_Type

function Get_Type return Glib.GType

Return Value

Gtk_Closure_Expression

type Gtk_Closure_Expression is access all Gtk_Closure_Expression_Record'Class;

Gtk_Closure_Expression_Record

type Gtk_Closure_Expression_Record is new Gtk_Expression_Record with null record;

Gtk_New

procedure Gtk_New
  (Self       : out Gtk_Closure_Expression;
   Value_Type : GType;
   Closure    : System.Address;
   Params     : Gtk.Expression.Gtk_Expression_Array)

Creates a GtkExpression that calls closure when it is evaluated. closure is called with the this object and the results of evaluating the params expressions. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Value_Type

the type of the value that this expression evaluates to

Closure

closure to call when evaluating this expression. If closure is floating, it is adopted

Params

expressions for each parameter

Initialize

procedure Initialize
  (Self       : not null access Gtk_Closure_Expression_Record'Class;
   Value_Type : GType;
   Closure    : System.Address;
   Params     : Gtk.Expression.Gtk_Expression_Array)

Creates a GtkExpression that calls closure when it is evaluated. closure is called with the this object and the results of evaluating the params expressions. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Value_Type

the type of the value that this expression evaluates to

Closure
