class WxReactor(_threadedselect.ThreadedSelectReactor): (source)

View In Hierarchy

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 ThreadedSelectReactor:

Method __init__ Undocumented
Method addReader Add a FileDescriptor for notification of data available to read.
Method addWriter Add a FileDescriptor for notification of data available to write.
Method callLater See twisted.internet.interfaces.IReactorTime.callLater.
Method doThreadIteration Undocumented
Method ensureWorkerThread Undocumented
Method getReaders Return the list of file descriptors currently monitored for input events by the reactor.
Method getWriters Return the list file descriptors currently monitored for output events by the reactor.
Method interleave interleave(waker) interleaves this reactor with the current application by moving the blocking parts of the reactor (select() in this case) to a separate thread. This is typically useful for integration with GUI applications which have their own event loop already running.
