wxPython crashes when run

[kdt]

Hi,

My GUI keeps crashing on the second time it runs. It doesn't come up with any useful error messages, just says "there was a problem". I've narrowed the offending code to the following.

I'm running wxpython on windows xp.

cheers

[CODE=python]

import wx

class myFrame(wx.Fram e):
def __init__(self, parent, id, title):
wx.Frame.__init __(self, parent, id, title, size=(250, 150))

menubar = wx.MenuBar()
file = wx.Menu()
quit = wx.MenuItem(fil e, 1, '&Quit\tCtrl+Q' )
file.AppendItem (quit)

self.Bind(wx.EV T_MENU, self.OnQuit, id=1)

menubar.Append( file, '&File')
self.SetMenuBar (menubar)

self.Centre()
self.Show(True)

def OnQuit(self, event):
self.Close()

class MyApp(wx.App):
def OnInit(self):
frame =myFrame(None,-1,"frame test")
self.SetTopWind ow(frame)

print "Print statements go to this stdout window by default."

frame.Show(True )
return True

app = MyApp(False)
app.MainLoop()

[/CODE]

I ran this successfully on my machine many times in a row with no errors.
The only thing that I see as a "mistake" is using a literal for the ID of the menu item. A better method would be to have wx give you IDs at the module level:[CODE=python]wxID_MYMENUITEM S0 = wx.NewId()[/CODE]The create the menu item and Bind() using that ID.

The reason that it is a mistake to use literals as IDs is that many IDs are used internally by wx. wx.NewId() will always return a usable ID.

Thanks Bartonc, resolved now. :)
