Gtk.Cclosure_Expression

Description

A variant of GtkClosureExpression using a C closure.

C_Marshaller

type C_Marshaller is access procedure
  (Closure         : System.Address;
   Return_Value    : Glib.Values.GValue
   N_Params        : Glib.Guint
   Params          : Glib.Values.C_GValues;
   Invocation_Hint : System.Address;
   Marsh_Data      : System.Address);

Parameters

Closure

Return_Value

Will contain returned value

N_Params

Number of entries in Params

Params

Invocation_Hint

Marsh_Data

Create

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

Parameters

Object

Return Value

Gcallback

type Gcallback is access procedure;

GClosureNotify

type GClosureNotify is access procedure
  (Data    : System.Address;
   Closure : System.Address);

Parameters

Data

Closure

Get_Type

function Get_Type return Glib.GType

Return Value

Gtk_Cclosure_Expression

type Gtk_Cclosure_Expression is access all Gtk_Cclosure_Expression_Record'Class;

Gtk_Cclosure_Expression_Record

type Gtk_Cclosure_Expression_Record is new Gtk_Expression_Record with null record;

Gtk_New

procedure Gtk_New
  (Self          : out Gtk_Cclosure_Expression;
   Value_Type    : GType;
   Marshal       : C_Marshaller;
   Params        : Gtk.Expression.Gtk_Expression_Array;
   Callback_Func : Gcallback;
   User_Data     : System.Address;
   User_Destroy  : GClosureNotify)

Creates a GtkExpression that calls callback_func when it is evaluated. This function is a variant of [ctorGtk.ClosureExpression.new] that creates a GClosure by calling g_cclosure_new with the given callback_func, user_data and user_destroy. 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

Marshal

marshaller used for creating a closure

Params

expressions for each parameter

Callback_Func

callback used for creating a closure

User_Data

user data used for creating a closure

User_Destroy

destroy notify for User_Data

Initialize

procedure Initialize
  (Self          : not null access Gtk_Cclosure_Expression_Record'Class;
   Value_Type    : GType;
   Marshal       : C_Marshaller;
   Params        : Gtk.Expression.Gtk_Expression_Array;
   Callback_Func : Gcallback;
   User_Data     : System.Address;
   User_Destroy  : GClosureNotify)

Creates a GtkExpression that calls callback_func when it is evaluated. This function is a variant of [ctorGtk.ClosureExpression.new] that creates a GClosure by calling g_cclosure_new with the given callback_func, user_data and user_destroy. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

the type of the value that this expression evaluates to

Marshal

marshaller used for creating a closure

Params

expressions for each parameter

Callback_Func

callback used for creating a closure

User_Data

user data used for creating a closure
