Closure.this

Allocates a struct of the given size and initializes the initial part as a #GClosure. This function is mainly useful when implementing new types of closures.

|[<!-- language="C" --> typedef struct _MyClosure MyClosure; struct _MyClosure { GClosure closure; // extra data goes here };

static void my_closure_finalize (gpointer notify_data, GClosure *closure) { MyClosure *my_closure = (MyClosure *)closure;

// free extra data here }

MyClosure *my_closure_new (gpointer data) { GClosure *closure; MyClosure *my_closure;

closure = g_closure_new_simple (sizeof (MyClosure), data); my_closure = (MyClosure *) closure;

// initialize extra data here

g_closure_add_finalize_notifier (closure, notify_data, my_closure_finalize); return my_closure; } ]|

  1. this(GClosure* gClosure)
  2. this(uint sizeofClosure, ObjectG object)
  3. this(uint sizeofClosure, void* data)
    class Closure
    this
    (,
    void* data
    )

Parameters

sizeofClosure uint

the size of the structure to allocate, must be at least sizeof (GClosure)

data void*

data to store in the @data field of the newly allocated #GClosure

Return: a newly allocated #GClosure

Throws

ConstructionException GTK+ fails to create the object.
