## Detailed Description

Idle signal class.

IdleSignal is a convenience class that adds a callback slot to the default main context, to be called whenever there are no higher priority events pending. If your using a different context, for example, inside a thread, you should use an IdleSource instead. If a connected slot returns false it is automatically removed from the list of event sources and will not be called again.

## Member Function Documentation

sigc::connection Xfc::G::IdleSignal::connect | ( | const SlotType & | slot,
|  | int | priority = `PRIORITY_DEFAULT_IDLE`
| ) |

  | Connect a slot to be called when the event loop is idle. Parameters:
  | slot | The slot to call.
  | priority | The priority which should not be above G::PRIORITY_HIGH_IDLE.
Returns: A connection object that can be used to break or alter the connection. You can give a priority different from G::PRIORITY_DEFAULT_IDLE to the idle function. Note that you will interfere with GTK+ if you use a priority above G::PRIORITY_RESIZE. The user function returns false to remove itself or true to have it called again.
