wxpython GUI and multiprocessing - how to send data back from the long running process -

A wxpython is trying to run a time consuming task from GUI with the original idea long (by pressing a button) GUI To start the work and after that, a constant text on the dialog should be updated.

I first saw some threading (and many other resources), and I want to show the messages back using Publisher.class. It did not go well, after the message or two, the GUI seems frozen.

Now I want to achieve it with multiprocessing. I have this method inside the 'GUI' class:

  def do_update (auto, e): self.txt_updatemsg.SetLabel ("do not stop it \ n") ... pub = publisher () # I was trying to call directly from dbob object # Publisher () is a singleton so it should be useless? Pub.subscribe (auto.__ update_txt_message, ('updatedlg', 'message')) dbob = dbutils.DBUtils () # DBUtils is a class with 'long time' functions dbob.publisher = pub p = process (target = self.do_update_process , Args = (dbob,)) p.is_alive: p.is_alive: wx.Yield def do_update_process (auto, dbob): dbob.do_update ()  

__ update_txt_message is a simple task Sets static text on dialog

The question is: how can I send back some text messages (just plain text, this is just me) thanks guys!

PubModule is not able to exceed the process boundaries.

So I have fixed my problem using threading, so I have to use classes provided by multiprocessing module, or some other inter-process communication method. Module
