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

Connects an idle handler.

bool idle_handler() { ... }

is equivalent to:

bool idle_handler() { ... }
idle_source->connect(sigc::ptr_fun(&idle_handler));
Parameters
slotA slot to call when the main loop is idle. If idle_handler() returns false the handler is disconnected.
priorityThe 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 
)

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