wxTimer problem

[abcd]

I have a python script which creates a wx.App, which creates a wx.Frame
(which has a wx.Timer).

looks sorta like this:

class MyProgram:
def __init__(self):
self.app = MyApp(0)
self.app.MainLo op()

class MyApp(wx.App):
def OnInit(self):
self.myframe= MyFrame()
self.myframe.Sh ow(True)
self.SetTopWind ow(self.myframe )
return True

class MyFrame(wx.Fram e):
def __init__(self):
# do some other stuff here

# setup the timer
self.timer = wx.Timer(self)
self.Bind(wx.EV T_TIMER, self.OnTimer, self.timer)
self.timer.Star t(100)

def killTimer(self) :
self.Unbind(wx. EVT_TIMER)
self.timer.Stop ()
self.timer = None
.....that's the jist of it.

Anyhow, so I startup python and import my script, which loads up the
wx.App, frame and all.

foo = MyProgram()
Then I close the frame. when the frame is closed it calls killTimer.
This method gets called and no exceptions occur.

Then...I create a new instance of the app and try to load the frame
again.

foo = MyProgram()

....and I am getting this error:

"timer can only be started from the main thread"

how can I fix this??

FYI, my script is being started by a new thread each time, so
ultimately we have....

def startProgram():
foo = MyProgram()

threading.Threa d(target=startP rogram).start()
Thanks in advance.

Fix: Start the script from the main thread only.

thanks for NO help.....anyway s, I got rid of the Timer b/c all i was
using it for was to check the state of the "shift" key.....but I am now
binding to key up/down.

You must not access wx from more than one thread. Read their wiki about
this and about the appropriate workaround.
