Detailed Description

IO signal class.

IOSource is a convenience class that adds a callback slot to the default main context, to be called when a given condition is met. If your using a different context, for example, inside a thread, you should use an IOSource instead. If a connected slot returns false it is automatically removed from the list of event sources and will not be called again.
