Function

GObjectsignal_handler_block

Declaration [src]

void
g_signal_handler_block (
  GObject* instance,
  gulong handler_id
)

Description [src]

Blocks a handler of an instance so it will not be called during any signal emissions unless it is unblocked again.

The handler_id has to be a valid signal handler id, connected to a signal of instance.

Parameters

instance GObject
 

The instance to block the signal handler of.

 The data is owned by the caller of the function.
handler_id gulong
 

Handler id of the handler to be blocked.
