:mrdocs:

Connect the specified `slot`, a callable object which must meet the `Slot Object Requirements` described in the component documentation, to this signaler. Optionally specify a `group` used to order slots upon invocation. Return an instance of `SignalerConnection` representing the created connection. This function meets the strong exception guarantee. Note that the connected slot may be called by a signal emitted from another thread before this function completes. Also note that it is unspecified whether connecting a slot while the signaler is emitting will result in the slot being called immediately. Note that `t_FUNC` may have a return type other than `void`, but in that case, when the slot is called, the return value will be discarded.
