Implements interfaces: twisted.internet.interfaces.IReactorFDSet

GTK+ event loop reactor.
Instance Variables_readsA dictionary mapping FileDescriptor instances to gtk INPUT_READ watch handles.

_simtagA gtk timeout handle for the next simulate call.
Method __init__ Initialize the file descriptor tracking dictionaries and the base class.
Method addReader I add reader to the set of file descriptors to get read events for.
Method addWriter I add writer to the set of file descriptors to get write events for.
Method getReaders Return the list of file descriptors currently monitored for input events by the reactor.

Method removeAll Remove all readers and writers.
Method removeReader Removes an object previously added with addReader.
Method removeWriter Removes an object previously added with addWriter.
Method doIterationTimeout Undocumented
Method doIteration Do one iteration over the readers and writers which have been added.
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 callback Undocumented
Method simulate Run simulation loops and reschedule callbacks.
Method _readAndWrite Undocumented

Inherited from PosixReactorBase:

Method installWaker Install a `waker' to allow threads and signals to wake up the IO thread.
Method spawnProcess Spawn a process, with a process protocol.
Method listenUDP Connects a given DatagramProtocol to the given numeric UDP port.
Method connectUDP DEPRECATED.

Method listenSSL
Method listenWith Start an instance of the given portType listening.
Method connectWith Start an instance of the given connectorType connecting.
Method _disconnectSelectable Utility function for disconnecting a selectable.
Method _checkMode Check mode to see if a value was specified for it and emit a deprecation warning if so. Return the default value if none was specified, otherwise return mode.
Method _removeAll Remove all readers and writers, and return list of Selectables.

Inherited from _SignalReactorMixin (via PosixReactorBase):

Method startRunning Extend the base implementation in order to remember whether signal handlers should be installed later.
Method mainLoop Undocumented
Method _handleSignals Install the signal handlers for the Twisted event loop.
Method _handleSigchld Reap all processes on SIGCHLD.
Method _reallyStartRunning Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.
