Hello,
I have an application with a db update dialog: a static text and two buttons. One of the button is bind with the do_update method which uses multiprocessing module to run a long task in the background. To communicate from there, I use Publisher() class. A receiver for that is set up in the Dialog, so I can receive messages from the work in the background.
But when I try to upload the StaticText Label, I get nowhere.
Could you figure out why?
Here is some code:
class DbUpdateDlg(wx.Dialog):
"""update the database"""
def __init__(self, parent = None):
wx.Dialog.__init__(self, parent, title="Actualizează baza de date", size=(500, 200))
Publisher().subscribe(self.__update_txt_message, ('updatedlg', 'message'))
...
txt_updatemsg = wx.StaticText(panel, 0, label=text)
...
def do_update(self, e):
self.txt_updatemsg.SetLabel("Dont stop this! \n")
self.btn_update.Disable()
self.btn_cancel.Disable()
p = Process(target=self.DBob.do_update)
p.start()
while p.is_alive():
wx.GetApp().Yield(True)
if not p.is_alive():
self.btn_cancel.Enable()
....
....
def __update_txt_message(self, message):
self.txt_updatemsg.SetLabel(message.data)DBob is a class in another module with do_update:
def do_update(self):
"""make the update for whole db"""
Publisher().sendMessage(('updatedlg', 'message'), "some msg")
wx.Sleep(5)
returnWhen I run the script, I get messages in __update_txt_message but SetLabel fails!
Weird thing is that if I put a GetLabel right after SetLabel I see the new value!
Any ideas?
Thanks!
