I've recently been trying out various different GUI frameworks in Python and
was wondering if I could get your input on the pros and cons of the
different ones...
wxPython: I love the programming side of wxPython, but I find it's just so
slow to initialise in the first place.
Tkinter: While it's fast to load up, the syntax has never really appealed to
me
GTK: Unknown - I'm looking into it today
Qt: I have yet to manage to install it on my system
Anything else?

Yeah - it is... I'n only developing for Linux here...
It's false.
I'm developping a gtk program which run in both linux and windows.
Sorry - when I answered the original question I thought he was asking if I was developing for Linux only... looking back, I have no idea why I got that idea....

Running that repeatedly (sorry, can't reboot conveniently

That is what Windows does. Using an oft used cliche in a different
realm that always made me laugh, "Don't hate the player, hate the game".
In this case, the player is wxPython, the game is 'running on Windows'.
There may be some method to tell windows to evict currently unused dlls,
but I wouldn't hold my breath.

No! GTK is most definitely cross platform. I use it on both Windows
and Linux with great success. And it's very consistent in the sense
that my GUI looks identical on both platforms. I have almost no need
for any platform dependent code in my GUI layout. (Unlike Tkinter and
wxPython where I remember having to tweek fonts and other things on a
platform by platform basis.)
Here's several pointers: http://www.async.com.br/faq/pygtk/in...=faq21.012.htp http://www.pcpm.ucl.ac.be/~gustin/win32_ports/

There's no (working) native port for Mac OS X [1], so I'd call it only mostly
cross-platform. You could use the X version, and run an X server, but
I could argue you could do the same under Windows...
[1] there are some partly-complete ports of GTK 1.2, but nothing for
GTK 2.x

The first time I launched IDLE, it took almost three seconds. (I don't

it takes about one second as well.
I'm curious about the differences with wxPython. Three seconds seems
unusually long when on a slightly slower machine I can do it in well
under a second. Was that the first time you ran it? Many other apps
open? I have over 256MB RAM free when I try this...
-Peter
Running Hugh's timing script from the command prompt, right after a
reboot, I get 1.1 seconds. Then on successive runs I get between 0.1 and
0.2 seconds. Then I ran the wx demo (without rebooting) and it was just
under 1.5 seconds for the splash. On successive runs it was well under 1
second.
So, maybe wxPython's not as bad as I thought. It's like my car in the
winter: I need to run out and start it up every few hours to make sure I
can make it home. ;)

I'm really sorry for my ignorance of pyGTK in Windows. I've installed pyGTK
in my desktop by following Jon's reply message.
I feel it's really so cool, after run a helloworld application.

'Programming Python' has an excellent introduction.. so I started with
Tkinter thinking that when I hit restrictions I could move onto wx. I
haven't yet reached the point where Tkinter restricts me. Whereas
there are a couple of widgets missing from the standard distribution,
Tkinter *can* be used to make clean and modern looking interfaces.....
And the syntax isn't too gawky once you've climbed the initial
learning curve.
For me, the issue with TK is less the restrictions it imposes and more the way of writing it in the first place.
I guess there are two 'warts' :
callback functions are usually called without parameters.
Wrapping the GUI framework in a class gets round this nicely - the
callback function has full access to the class instance attributes.
The second is the way that events are triggered with an event object :
self.searchbox. bind('<Return>' , (lambda event: self.search()))
Using a lambda function to trigger a callback function gets round
that.
Once you get used to the pack order with Tk it's remarkably easy to
build GUIs quickly....
I guess for *big* applications some of the 'power' widgets might be
missing from the standard distribution. In that sense wx is
undoubtably more polished and fully featured.... But so far for me -
Tk has more than covered my needs without even exploring extension
widget sets. Apparently one of the more high powered IDEs (I forget
which one) is seamlessly built from Tk widgets.... but you'd never
realise it to look at it - so I guess the potential is there.

(pardon my terrible ignorance...)
Yeah - it is... I'n only developing for Linux here...
Qt: I have yet to manage to install it on my system
Although *technically* cross platform, windoze users can't get a free
version... so I'm never going to bother looking at it...
That doesn't bother me - everything I'm writing is for in-house use only, and would only ever be run on Linux...
Thanks for everyones thoughts... I'm actually planning on sticking with wxPython for the moment. I've decided that I can live with the extra few seconds to load up, although I don't like it...

In this case, the player is wxPython, the game is 'running on Windows'.
After stopping the wxpython app Windows reports its memory share as
free, i.e. usable for other applications. If the same application
is reloaded and its binary stuff is not yet overwritten it is reused.
That's a good thing IMO, not a flaw. It would be nice though to
configure this behaviour, e.g. for testing. Perhaps there's a
registry spell in one of the numerous guru books for Win* but my
interest doesn't go this far.
