I figured it out. The problem here is that the PyCommandEvent and
PyEvent have the args in the opposite order!!!
wx.PyEvent.__init__(self, id, evtType)
Vs
Wx.PyCommandEvent.__init__(self, evtType, id)
I had copied the event class from a custom event class based on
PyCommandEvent. The event class I used was:
class LogEvent(wx.PyEvent):
def __init__(self, evtType, id):
wx.PyEvent.__init__(self, evtType, id)
That seems very error prone. Especially since you don't get an error,
it just doesn't fire the event as expected.

Robin,
If logger is an instance of Logger and I have the line:
logger.Bind(Logger.EVT_LOG, self.OnLogChange) In another object (not a
Logger object). Will that not cause the event to be processed by
self.OnLogChange in the other object? Below is how I thought this would
work. Maybe you can tell me where my understanding is wrong.
# inside the LogGUIWindow __init__
#1) create a Logger instance
self.logger = Logger()
#2) this adds an entry to the logger's event table for EVT_LOG pointing
to self.OnLogChange self.logger.Bind(Logger.EVT_LOG, self.OnLogChange)
#inside Logger.logWrite
#3) create a log event object
evt = LogEvent(myEVT_LOG, self.id)
#4) set the event object to this logger
evt.SetEventObject(self)
#5) call self.ProcessEvent - This will find the entry in the event table
added by (2) above??
self.ProcessEvent(evt)

Hey,
Below is part of a class I wrote for logging user actions in my app.
I was trying to allow the log gui to get an event whenever the log
changed. TO do this I derived from wx.EvtHandler and then proceeded
much the same as I would for a control with a custom event. I can't
get it to work. The Log gui never gets the event. Is this the wrong
way to go about this?The log gui uses the line below to bind the event:
logger.Bind(Logger.EVT_LOG, self.OnLogChange)The rest is a portion of my Logger class and it's event class:
myEVT_LOG = wx.NewEventType()
EVT_LOG = wx.PyEventBinder(myEVT_LOG, 1)class LogEvent(wx.PyEvent):
def __init__(self, evtType, id):
wx.PyEvent.__init__(self, evtType, id)class Logger(wx.EvtHandler):
def __init__(self):
wx.EvtHandler.__init__(self)
self.log =
self.id = wx.NewId()def GetId(self):
return self.iddef logWrite(self, device, interface, field, value):
self.log.append(('write',time.time(),device,interface,field,value))
evt = LogEvent(myEVT_LOG, self.id)
evt.SetEventObject(self)
self.ProcessEvent(evt)
Where do you want the event to go at this point? As you have it written
the event will only be sent to self, so you need to do a self.Bind to
connect a handler for it. If you are wanting the event to be sent to
some other object then you need to do otherObject.ProcessEvent(evt).
