Function
GObjectClosurenew_simple
Description
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:
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;
}
