wxPython reactor.

wxPython drives the event loop, select() runs in a thread.

Method registerWxApp Register wxApp instance with the reactor.
Method run Start the reactor.
Method stop Stop the reactor.
Instance Variable wxapp Undocumented
Method _installSignalHandlersAgain wx sometimes removes our own signal handlers, so re-add them.
Method _runInMainThread Schedule function to run in main wx/Twisted thread.
Method _stopWx Stop the wx event loop if it hasn't already been stopped.
Instance Variable _postQueue Undocumented
Instance Variable _stopping Undocumented

Inherited from PosixReactorBase (via ThreadedSelectReactor):

Method adoptDatagramPort Add an existing listening SOCK_DGRAM socket to the reactor to monitor for read and write readiness.
Method adoptStreamConnection
Method adoptStreamPort Create a new IListeningPort from an already-initialized socket.

Method connectUNIX Connect a client protocol to a UNIX socket.
Method connectUNIXDatagram Connects a ConnectedDatagramProtocol instance to a path.
Method installWaker Install a `waker' to allow threads and signals to wake up the IO thread.
Method listenMulticast Connects a given DatagramProtocol to the given numeric UDP port.
Method listenSSL Connects a given protocol factory to the given numeric TCP/IP port. The connection is a SSL one, using contexts created by the context factory.
Method listenTCP Connects a given protocol factory to the given numeric TCP/IP port.
Method listenUDP Connects a given DatagramProtocol to the given numeric UDP port.
Method listenUNIX Listen on a UNIX socket.
Method listenUNIXDatagram Connects a given DatagramProtocol to the given path.
Method spawnProcess Spawn a process, with a process protocol.
Instance Variable waker Undocumented
Method _handleSignals Extend the basic signal handling logic to also support handling SIGCHLD to know when to try to reap child processes.
Method _removeAll Remove all readers and writers, and list of removed IReadDescriptors and IWriteDescriptors.
Method _uninstallHandler If a child waker was created and installed, uninstall it now.
Class Variable _supportedAddressFamilies Undocumented
Instance Variable _childWaker None or a reference to the _SIGCHLDWaker which is used to properly notice child process termination.

Inherited from _SignalReactorMixin (via ThreadedSelectReactor, PosixReactorBase):

Method startRunning Extend the base implementation in order to remember whether signal handlers should be installed later.
Method _reallyStartRunning Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.
Instance Variable _installSignalHandlers 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 ThreadedSelectReactor, PosixReactorBase):

Method _disconnectSelectable Utility function for disconnecting a selectable.

Inherited from ReactorBase (via ThreadedSelectReactor, PosixReactorBase):

Instance Variable _exitSignal See _ISupportsExitSignalCapturing._exitSignal
Instance Variable _internalReaders Undocumented
Instance Variable _justStopped 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 _newTimedCalls Undocumented

Instance Variable _startedBefore 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.
