signalHandlerBlock
fn
void signalHandlerBlock(gobject.object.ObjectWrap instance, gulong handlerId)Blocks a handler of an instance so it will not be called during any signal emissions unless it is unblocked again. Thus "blocking" a signal handler means to temporarily deactivate it, a signal handler has to be unblocked exactly the same amount of times it has been blocked before to become active again.
The handler_id has to be a valid signal handler id, connected to a signal of instance.
Parameters
instance | The instance to block the signal handler of. |
handlerId | Handler id of the handler to be blocked. |
