class PortableGlibReactorBase(selectreactor.SelectReactor): (source)

Known subclasses: twisted.internet.gireactor.PortableGIReactor, twisted.internet.gtk2reactor.PortableGtkReactor

View In Hierarchy

Base class for GObject event loop reactors that works on Windows.

Sockets aren't supported by GObject's input_add on Win32.

Method __init__ Initialize file descriptor tracking dictionaries and the base class.
Method crash See twisted.internet.interfaces.IReactorCore.crash.
Method run Fire 'startup' System Events, move the reactor to the 'running' state, then run the main loop until it is stopped with stop() or crash().
Method simulate Run simulation loops and reschedule callbacks.

Inherited from _SignalReactorMixin (via SelectReactor, PosixReactorBase):

Method main​Loop Undocumented
Method start​Running Extend the base implementation in order to remember whether signal handlers should be installed later.
Method _really​Start​Running Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.
Instance Variable _install​Signal​Handlers A flag which indicates whether any signal handlers will be installed during startup. This includes handlers for SIGCHLD to monitor child processes, and SIGINT, SIGTERM, and SIGBREAK to stop the reactor.

Inherited from _DisconnectSelectableMixin (via SelectReactor, PosixReactorBase):

Method _disconnect​Selectable Utility function for disconnecting a selectable.

Instance Variable _just​Stopped A flag which is true between the time reactor.stop is called and the time the shutdown system event is fired. This is used to determine whether that event should be fired after each iteration through the mainloop. This should be replaced with an explicit state machine.

Instance Variable _started​Before Undocumented
Instance Variable _stopped A flag which is true between paired calls to reactor.run and reactor.stop. This should be replaced with an explicit state machine.

Fire 'startup' System Events, move the reactor to the 'running' state, then run the main loop until it is stopped with stop() or crash().
def simulate(self): (source)
Run simulation loops and reschedule callbacks.
