Write a GUI for a python script?

[Glurt Wuntal]

I am a newbie with Python. It's a great language, but I would like to be
able to present a simple gui menu for some of my scripts; something better
than using 'raw_input' prompts.

Any recommendations for a program that will allow me to create the gui
screens? Something useable in Linux.

thanks.

Tkinter is the GUI toolkit that comes with Python and is available on
all platform without any
installation effort. It is quite OK for simple things and I would
recommend it for any beginner.
Google for "An Introduction to Tkinter" by F. Lund.

wxPython is another good option, especially since there is
boa-constructor, which is a great GUI builder, almost makes it too easy
to make a nice looking app in no time at all.

http://www.wxpython.org/download.php

http://boa-constructor.sourceforge.net/

if you decide to give wxPython a go, make sure to download the demo, it
has tons of usefull code samples.

What is the minimal memory footprint of a Hello World wxPython app
meanwhile (when you cx_freeze/py2exe it) ?

Can you debug & call functions interactively from e.g. Pythonwin while a
wxPython app is running.

( When I made a test with wxPython some years ago, it had no option to
step/share its Messageloop. Interaction was "crust"y and I didn't manage
to get smooth debugging (on Windows). )

There are Python bindings to most GUI toolkits (GTK+, Qt, fltk, wxWindows,
and Tk come to mind). You could use any of them. They're all usable in
GNU/Linux.

-- Tk is a mature, small, and simple toolkit. The Python binding
to Tk is called Tkinter.

-- GTK+ is what most Gnome apps use. The Python binding is PyGTK.
http://www.pygtk.org/

-- Qt is what most KDE apps use. The Python binding is called PyQt.

-- wxWindows is a lot like MS Windows MFC if I recall correctly.
The Python binding to wxWindows is called wxPython.

-- For a terminal-based text-mode character-cell display program, you
could use ncurses. http://www.amk.ca/python/howto/curses/

Whoops. Forgot fltk with the pyFLTK Python binding. fltk
is a fast, light, toolkit that's written in C++ but (again,
IIRC) feels more like C-with-classes (which isn't a bad thing).

It's a snap to incorporate a nice GUI Python shell with object browser
into any wxPython app - wxPython provides its PyCrust shell as a
package, which provides your choice of a widget you can embed or a
top-level window you can create. In one app I worked on I created a
menu item that launched such a shell window, so I could poke around
inside the app.

As far as actual debugging/stepping... I'm not sure. I haven' thad much
luck with Python debugging using anything but Wing IDE.

I'm assuming you mean disk space and not memory usage. A stock
wxPython (from a standard release) wil vary from platform to platform
but is generally about 2.5 megs. This can be brought down rather a lot
if you're willing to spend a fair amount of time learning the
wxWidgets and wxPython build systems and making custom builds but it's
not generally worth the time to me (and I know the build system and
could make customized builds if I wanted to)

I have a non-trivial wxPython application and, using py2exe in "single
executable" mode (thus all the dlls and the zipfile with the .pyc
files are included in the exe) it's just over 5 megs in size.
Can you debug & call functions interactively from e.g. Pythonwin while a
wxPython app is running.

I've never tried it with PythonWin and I don't know how PythonWin
hooks into Python to manage debugging). Both pdb and the debugger in
PyDev work fine for me, however. As another responder said it's
trivial (literally < 5 lines) to add an interactive Python shell to a
wxPython application, which is invaluable for debugging and testing.
( When I made a test with wxPython some years ago, it had no option to
step/share its Messageloop. Interaction was "crust"y and I didn't manage

I don't believe that wxPython exposes the low level C++ APIs that're
available to hook the wx message loop (it's an efficency issue, from
what I understand), but there are a number of other methods for
integration. The need to hook the message loop is far far less common
than the number of people who ask for it, so you'll forgive me if I'm
skeptical unless someone actually says why they want to.

it's kinda weird actually... I'm not 100% sure, but i think it relates
more to py2exe options, not neccessarily to wxPython. in any case the
least memory usage i've seen for an app that has at least some degree
of functionality is around 12k running on win2000. But a much more
complicated and larger app uses about 16k, while another small app uses
like 20k...

Note that wxWindows wraps native widgets, so a wxPython application
will use the native Windows widgets on windows, gtk widgets on
Linux/GNOME, Mac widgets on the Mac, etc.

I usually use wxPython for application development, but for my window
manager I'm using pygtk since it needs to be somewhat lower level and
portability to other platforms isn't a concern (turns out even that
isn't quite low-level enough for some things, so I drop down to
accessing the X event queue directly from C in a couple of cases).
