Thought I'd put together a small example to show what I mean:
import pygtk
pygtk.require("2.0")
import gtk
import sys
import time
def do_stuff():
time.sleep(5)
print 'brian'
####################################
# >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> handles
####################################
class handles:
def on_login_window_destroy(event):
sys.exit(1)
####################################
# >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> define main
####################################
class LoginApp:
def __init__(self):
# set the glade file
self.builder = gtk.Builder()
self.builder.add_from_file("login.glade")
self.window = self.builder.get_object("login_window")
self.builder.connect_signals(handles.__dict__)
self.server = self.builder.get_object("server")
self.info = self.builder.get_object("info")
self.window.show()
def __getitem__(self,key):
# provide link to widgets
return self.builder.get_object(key)
####################################
# >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> run application
####################################
if __name__ == '__main__':
ghs = LoginApp()
do_stuff()
gtk.main()
The window outline appears but no inside until after 5 sec when the full window
takes shape my name then appears.
What I want is the full window appearing at the beginning and then 5 sec later
my name appears.
Make sense?
Brian

The right answer really depends on what sort of things you are doing
inside do_stuff. If it's work that makes sense to move piecewise to
signal handlers, then do that. If it's a batch of work with convenient
locations to do event processing (say every time through a loop), call
gtk.main_iteration() from time to time, possibly within a while
gtk.events_pending().
Welcome to event-based programming!
