Any ides why? I highly recommend reading this wxPython wiki entry about using threads in wxPython: http://wiki.wxpython.org/LongRunningTasks I've found it quite helpful in my own programming.

It is the problem. It is usually not allowed to manipulate GUI-objects from any thread except the main-thread that runs the event-loop. All GUI-toolkits have guidelines how to cope with that, e.g. custom events in Qt3, or timers. This message indicates that WX has similar means: http://osdir.com/ml/python.matplotlib.general/2005-03/msg00208.html Diez -- http://mail.python.org/mailman/listinfo/python-list

wxpython application ( problem ? )
Hello, Here is sample of my simple script with wxpython and modules: subprocess,threading, directpython... Code sample: import wx import wx.aui app=wx.App() frame=wx.Frame(None,title="New project") #There is also part with wx.aui frame.Show() app.MainLoop() After a few minutes wx application does destroy. Any ides why? -- http://mail.python.org/mailman/listinfo/python-list
