Heh. Funny that I should be trying a similar thing. My situation is a
bit different: I've got the mainloop running already, and
in a loop of functions I need to update the display and then sleep. I do
this by using James' suggestion of mainiteration and it worked for me.
_However_, doing the _final_ update of the statusbar (where I set the
value to 1 and changed the label to say finished, it didn't. The
statusbar was never drawn in it's full and the label wasn't updated.
To get this to work, I did the UI updates and then did gtk.idle_add() of a
function that performed the rest of the task. This worked, but using
events_pending()/mainiteration() simply hung on me. Isn't that odd?
[ gtk.idle_add() is probably the most important function to look at then
"things seem darned unreasonable". It will let you work around a lot of
problems with the mainloop paradigm. ]
Take care,

gtk.mainloop() runs the main loop (until the gtk.mainquit is called).
gtk.mainiteration() runs a single iteration of the main loop, then
returns. As drawing is deferred to run during the main loop, if you don't
give time to it, your app won't redraw.
You can tell the main loop to run while there are events pending with the
following call:
while gtk.events_pending():
gtk.mainiteration()
Putting calls like that during the loading of your splash screen should
get things to draw.
James.

Re: [pygtk] mainloop vs mainiteration
I'm sorry, I've mispelled: the method is not mainiterator but
mainiteration; the question is the same: mainiteration vs mainloop

[pygtk] mainloop vs mainiterator
Hi to all,
I've created a small class that show a splash screen with an image and a
progressbar. At the end of my module I've add some lines for test the
class:
if __name__=="__main__":
sp=Splash_screen("splash_screen.png",1)
sp.show()
sp.bar_update("carico", 0.1)
time.sleep(4)
sp.bar_update("carico", 0.4)
time.sleep(3)
sp.bar_update("carico", 0.9)
time.sleep(0.1)
gtk.mainloop()
The window is not shown correctly (basically the bar was never updated
)and I'm quite sure that the problem is the mainloop call. I've noticed
that the gtk module has also a mainiterator method that probably is what
I need: can you please tell me what's the difference between mainloop
and mainiterator ?
Best Regards
Pier Carteri
