Re: Can we use g_boxed_type_register_static type with g_signal_new ?

Thank you for your help...

Why ?

(dbx) p item

As you can see, this value is not a pointer !!!

But the good value is in var_args of g_signal_emit_valist().

This value is extracted from var_args in g_signal_emit_valist()

 +2528        g_value_init (param_values + i, ptype);
 +2529        G_VALUE_COLLECT (param_values + i,
 +2530                         var_args,
+2531 static_scope ? G_VALUE_NOCOPY_CONTENTS : 0,
 +2532                         &error);

but it seems that G_VALUE_COLLECT() cannot manage correctly the type to
extract the value.

I think this type comes from g_signal_new(), it's a GBoxed type.

Where is the problem ?
