A GObject.CClosure is a specialization of GObject.Closure for C function callbacks.
classmethod marshal_BOOLEAN__BOXED_BOXED(closure, return_value, n_param_values, param_values, invocation_hint, marshal_data)[source]¶
Parameters:
- closure (GObject.Closure) – A GObject.Closure.
- return_value (GObject.Value) – A GObject.Value to store the return value. May be Noneif the callback of closure doesn’t return a value.
- n_param_values (int) – The length of the param_values array.
- param_values (GObject.Value) – An array of GObject.Values holding the arguments on which to invoke the callback of closure.
