SignalHandler

Description:

Content:

Methods:

• public void block (void* instance, ulong handler_id)
  Blocks a handler of an instance so it will not be called during any signal emissions unless it is unblocked again.
• public uint block_by_func (void* instance, void* func, void* data)
• public uint block_matched (void* instance, SignalMatchType mask, uint signal_id, Quark detail, Closure? closure, void* func, void* data)
  Blocks all handlers on an instance that match a certain selection criteria.
• public void disconnect (void* instance, ulong handler_id)
  Disconnects a handler from an instance so it will not be called during any future or currently ongoing emissions of the signal it has been connected to.
• public uint disconnect_by_data (void* instance, void* data)
• public uint disconnect_by_func (void* instance, void* func, void* data)
• public uint disconnect_matched (void* instance, SignalMatchType mask, uint signal_id, Quark detail, Closure? closure, void* func, void* data)
  Disconnects all handlers on an instance that match a certain selection criteria.
• public ulong find (void* instance, SignalMatchType mask, uint signal_id, Quark detail, Closure? closure, void* func, void* data)
  Finds the first signal handler that matches certain selection criteria.
• public bool is_connected (void* instance, ulong handler_id)
  Returns whether handler_id is the ID of a handler connected to instance.
• public void unblock (void* instance, ulong handler_id)
  Undoes the effect of a previous block call.
• public uint unblock_by_func (void* instance, void* func, void* data)
• public uint unblock_matched (void* instance, SignalMatchType mask, uint signal_id, Quark detail, Closure? closure, void* func, void* data)
  Unblocks all handlers on an instance that match a certain selection criteria.
