## Member Function Documentation

sigc::connection Glib::SignalIdle::connect | ( | const sigc::slot< bool > & | slot,
|  | int | priority = `PRIORITY_DEFAULT_IDLE` |
| ) |  |  |

Connects an idle handler.

     Glib::signal_idle().connect(sigc::ptr_fun(&idle_handler));

is equivalent to:

     const Glib::RefPtr<Glib::IdleSource> idle_source = Glib::IdleSource::create();
     idle_source->connect(sigc::ptr_fun(&idle_handler));
     idle_source->attach(Glib::MainContext::get_default());

Parameters:

  | slot | A slot to call when the main loop is idle.
  | priority | The priority of the new event source.

Returns:
  A connection handle, which can be used to disconnect the handler.

void Glib::SignalIdle::connect_once | ( | const sigc::slot< void > & | slot,
|  | int | priority = `PRIORITY_DEFAULT_IDLE` |
| ) |  |  |

Connects an idle handler that runs only once.

This method takes a function pointer to a function with a void return and no parameters. After running once it is not called again.
