Memory dealocation using "destroy" signal /callback

[Toni Moreno Giménez <toni moreno gimenez wanadoo es>]

Hi.

I'm building my  own wdgets, most of them , uses dinamic allocated memory and 
I need to make sure that this memory is deallocated when the widtget is 
destroyed.

I would like to know what is best. replace the GtkObject destroy function or 
use a signal conecting "destroy" GtkObject Widget.

Anyway I need to know about the destroy process.
I can understand who make the call to the destroy function. 


I have tested this code, drawing my new widget. 
but de destroy funcion on my widget seems to be never called.

is the main loop who make the (GtkObject* (myobject))->destroy ??

-MIWIDGET.C--(Using Signal)--------------------------
.....

void my_destroy_func(GtkObject *ob,gpointer data)
{
	g_free(MY_WIDGET(ob)->any_data);
	printf("data have been destroyed");
}
....
void my_widget_init(MiWidget *mywid)
{
.....
 gtk_signal_connect(GTK_OBJECT(mywid),"destroy",GTK_SIGNAL_FUNC(my_destroy_fun
c),NULL);
}
......

.----MYWIDGET.C --(Using callback)---------------------

void my_destroy_func(GtkObject *ob,gpointer data)
{
	g_free(MY_WIDGET(ob)->any_data);
	printf("data have been destroyed");
}
....
void my_widget_class_init(MiWidgetClass *mywidk)
{
GtkObjectClass *klass=(GtkObjectClass*)mywidk;

	klass->destroy=my_destroy_func;
.....
	
}
....

--MAIN.C------------------------------------------

gint Delete(GtkWidget *widget,gpointer *data)
{
        gtk_main_quit();
 }


int main (int argc,char *argv[])
{
    GtkWidget *window,*wid;
 
/*GTK Initialization */
 
    gtk_init(&argc,&argv);
 
/*creating a window*/
 
    window=gtk_window_new(GTK_WINDOW_DIALOG);
    gtk_window_set_title(GTK_WINDOW(window),"test");
    gtk_signal_connect(GTK_OBJECT(window),
			"delete_event",
                                  GTK_SIGNAL_FUNC(Delete),NULL);
         

    wid=my_own_widget_new();
    gtk_container_add(GTK_CONTAINER(window), wid);
 
/*showing all */

    gtk_widget_show(skin);
    gtk_widget_show(window);
    gtk_main(); 

}

-------------------------------------


In any case, memory are not deallocated. what I'm doing wrong ?

Thaks in advance.
