Why not? It can certainly do what you want. As can virtually
any other GUI toolkit. But programming GUIs is much harder
than programming the console regardless of toolkit choice.

Here is a sample Tkinter program that displays text in
different colors:

###
from Tkinter import *

n = 0
top = Tk()
t = Text(top, width=25, height=2)
t.pack()

# set up tags for the colors
colors = ['red','blue','green']
for col in colors:
t.tag_config(col, foreground=col)

def addWords():
n = 0
for word in "Hello ", "bright ", "world ":
t.insert(END,word,colors[n])  #use the color tags
n +=1

Button(top,text="Add words",command=addWords).pack()

top.mainloop()
##

Most other GUIs will be similar.

[Tutor] GUI for ANSI colors

[Freedom Peacemaker]

Hi tutor,
I'm trying to put my script with randomly colored letters (ANSI escape
code) into GUI but cant find any. I've tried tkinter but it isn't good
choice. Then i was searching for capabilities of PyQt4 again without
success. Thats why im writing this message. Is there any GUI that can print
word with randomly colored letters?

>  Why is nothing showing up?

Because you have defined the GUI inside a class. But you
never instantiate that class so the code never gets executed.

However, there are several other issue that you should
think about...


import tkinter

class AddressGUI:
 def __init__(self):
 self.main_window = tkinter.Tk()

 self.top_frame= tkinter.Frame()


Your widgets, including Frames should always have
an explicit parent defined. Things can get awfully
confused otherwise and debugging what's happening
is a pain. So use self.main_window as your parent
for these frames.


 self.mid_frame= tkinter.Frame()
 self.bottom_frame = tkinter.Frame()

 self.name_label= tkinter.Label(self.top_frame,\
  text='Steven Marcus')

 self.name_label.pack(side='left')


 self.value = tkinter.StringVar()
 self.address_label = tkinter.Label(self.mid_frame,\
text='274 Baily Drive Waynesville, 
NC 27999')

 self.address_label.pack(side='left')

 self.show_button = tkinter.Button(self.bottom_frame,\
   text="show info",\
   command=self.showinfo)
 self.quit_button = tkinter.Button(self.bottom_frame,\
   tect ='Quit',\
   command=self.main_window.destroy)


Personally I'd probably use quit() rather than destroy(). The latter 
leaves the objects in memory, and the evebnt loop running, only removing 
the window widgets. quit() closes the event loop and

shuts things down a bit more thoroughly in my experience.



 self.show_button.pack(side='left')
 self.quit_button.pack(side='left')

 self.top_frame.pack()
 self.mid_frame.pack()
 self.bottom_frame.pack()

 tkinter.mainloop()


Its usually better to start the mainloop outside the application class.
Not least because it makes reuse easier. But also because it offers 
better control of initialisation/ finalisation actions.



 def showinfo(self):
 name = 'Steven Marcus'
 address = '274 Baily Drive Waynesville, NC 27999'
 info = name + address

 allinfo = AddressGUI()


And a recursive call to the app inside an event handler is a
recipe for confusion. You will have multiple instances around
in memory with potentially multiple event loops (see note on
destroy) above. Especially since you don;t even store a reference
to the new app instance. The allinfo variable gets deleted when
the method completes.

In general its a good idea to byui8ld your program in small
chunks.  Get a basic GUI with windows to display then add
the widgets one by one and test them as you go. Its much easier
to debug things when you only have a small amount of new code
to look at.

I, too, like wxPython, but I don't recall it having any explicit support

Still under development, true - but all but a few of the controls are up

(Not I - I'm still using 2.7 - but I've been following developments with

So wxPython Phoenix 1.0 doesn't get released until all controls are up

therefore could not recommend using it to someone who's trying to put a 
Hebrew Dictionary database together.  Much better IMHO to use something 
that's already proven in the field.

Python or Perl do much the same thing. Python is easier to read 
(although being a Python group I'm biased...)



the major features I hope to incorporate into the application:
 א) Hebrew keyboard application that will easily switch back and
forth between English and Hebrew character sets.  Key assignments will
be user defined or easily reprogrammed so that both standard and custom
configurations can be made: (ie similar to
http://www.lexilogos.com/keyboard/hebrew.htm )


I've no idea how you support that in a GUI. It may well be beyond the 
scope of this list too. I suspect that once you identify your target GUI 
framework that their support forums will be better suited to answer.



 ב) Dual screen editor for simplified search and replace (hebrew
with nikkud, with option to ignore the nikkud/vowels to find
shoreshim/roots) feature.  One window will be the compiled dictionary.
The second window will be any Hebrew text (Torah, Siddur, etc...).  The
application will--hopefully--automatically search the "dictionary" based
upon the current cursor and add the English definition of the Hebrew
word with a click or two.  (I'm learning Hebrew, as I go, studying every
week, if not every day.)


This sounds very advanced for a first project (but then, so is a device 
driver!) Certainly probably beyond this lists scope.



 ג) Obviously, a menu bar with tools and other standard GUI bits and

Yep, that kind of stuff we might help with. But again the GUI support 
forum is likely to be better still.

I'm running an older Debian Linux, that doesn't upgrade very well.  Is
there anybody willing to help me at least get started or point me in the
right direction?


We don't really provide 1-1 mentoring. You ask questions on the list and 
the list members answer. You might be very lucky and find someone who is 
familiar with your problem domain, but its a long shot.



Knowledge of Hebrew would be a *huge* plus, but isn't required in any
...  Thus, leafpad would be a reasonable model for the editor.


Again thats a pretty specialized set of skills on top of Python. You 
might try the main Python mailing list/nesgroup. You have a bigger 
audience there to find someone suitable to help you.

[Tutor] GUI

[D.Edmons]

Hi,

Background:
I've compiled both python2 and python3 and am starting to learn them 
well enough to do a GUI application that requires UTF-8.  I've done 
quite a bit of maintenance programming (fixing bugs, minor updates, etc) 
but the only major application I've written was a disk driver for RT-11X 
on Linux using FUSE (quite a project, considering that I had no 
specification!).


Anyway, I suspect that I'll have to use python3 to take advantage of the 
UTF-8 (is there a __FUTURE__ option for python2?).  I've done some very 
minor GUI stuff, but what I need is an application that will do Hebrew 
(left <-- right) that actually attempts to "get it right".  Also, I'm 
creating a Hebrew Dictionary database and my GUI will have to work with 
it (ie. it is the whole purpose of this exercise).

there anybody willing to help me at least get started or point me in the

database for five years now (using sqlite 3.7.3 and UTF-8 text). 
Knowledge of Hebrew would be a *huge* plus, but isn't required in any 
way.  I'm currently reading the Tutorials I've gleaned from the Python 
homepage.  I've never written more than trivial GUI applications.


I currently use leafpad for my UTF-8 editor.  Though it is a little 
buggy--this should be fixed if I can get my libraries uptodate--it 
handles the UTF-8 text as well as I expect it to, whereas others don't. 
 Thus, leafpad would be a reasonable model for the editor.


(btw, I got this e-mail link from the Website Tutorial which is supposed 
to be included in the distro--I haven't checked.)

I personally like GTK quite a lot. You can use a GUI designer like

PyQt or PySide offers QtDesigner. Which is a drag and drop builder.

[Tutor] GUI development with Python 3.4.1

[Juan Christian]

I need to develop a GUI for my Python pogram, I already read the
GuiProgramming page (https://wiki.python.org/moin/GuiProgramming). For me,
the best so far was 'gui2py'.

The problem is that I need a simple "C#/Java-ish" GUI builder, that is easy
and simple, coding all the GUI by hand is boring, I prefer to focus on the
logic, on the actual program code, than coding the GUI.

Anyone here already used 'gui2py' (https://github.com/reingart/gui2py)? Any
other good alternatives?

[Tutor] GUI for python Google App Engine

[Surya K]

Hi there,

I just wrote a small game in python and would like to make it a facebook app.
These are the things I wish to know:
1. How to write GUI for my app. I believe, PyQt or Wx wouldn't work in Google 
App Engine.2. How to integrate my app with facebook. I went through facebook 
documentation but couldn't get it clearly..
this is what I require as per the game:
Two players join a game and each player inputs a character..

Any small tutorials that would teach me would be appreciated.. 
Right now I don't want to learn about GAE or Facebook API in detail. I just 
want to build my app.

Do you have any experience with 3d programming? If you've already familiar
with OpenGL, you can use the pyglet framework that gives you OpenGL
bindings.

Of course, if you already have a way to do the 3d part, then your GUI
framework really doesn't matter - Tkinter is probably the easiest one to
use, wxPython give you native-looking widgets (if you're using Windows, your
apps will look like other Windows apps), PyGTK+ is great if you plan to use
the Gnome window manager under Linux, and PyQT is good for KDE and contains
everything but the kitchen sink. Also you'll be using your left pinky /all/
the time because everything you use has "q" in it.

If all you need to do is display an image and track where the mouse
click/drags are happening, I'd probably use Tkinter.

At the terminal, sudo apt-get install idle.

When you need software, search in Synaptic (Package Manager) or google

Re: [Tutor] GUI + python program

[Patrick Sabin]

You have a lot of options:

GUI: Any major gui toolkit will do the job. It's probobly easiest to 
stick with tkinter.


HTML Template: Use a template language, e.g. mako or django templates
Pdf Templates: Reportlab is an option.

File Access: Of course you could just open a file and write to it, but 
it probably gets messy. I would recommend using a database. Sqlite is 
maybe a good choice, or sqlalchemy.

I think the thing that helped me most was in my assembly class where I
actually created an event-driven painting program using non-blocking calls
to check the keyboard, etc.

That may be part of why GUI programming was so easy for me to pick up (and
as an extension, threading).

Try not to think of it as class based. Languages like Java tend to

Tkinter is, like most GUI toolkits heabvily based on objects itself.
But then, so is Python. Strings, files, lists etc are all objects in 
Python.

If you can use those you can use Tkinter.

Is there something about class based programming that GUI apps

GUIs are conceptially made up of objects - buttons, menus, windows,
scroll bars etc. There is a very natural mapping from the visual 
objects

(widgets/controls) that you see on-screen and the code objects of the
toolkit. The whole ethos of OOP is that each object is like an 
independent

mini-program responding to events/messages from other objects.
GUI windows reflect that model - a dialog box acts like a mini app
within the parent app and sends data back to it...


Does anyone have or know of a good tutorial or explanation of class

Try my tutor. It has topics on both OOP and GUIs.
And before doing the GUI one also  read the event-driven topic because
GUIs are, without exception, event-driven frameworks. Most folks find

There's nothing really wrong with a lot of functions, and that also
highlights one of the great advantages of Python - you can still program
procedurally or using any other type of paradigm, more or less.

Perfect, really. You can quickly throw a nice little GUI together with few
problems. And there are other people doing some rather
nice
things
with Tkinter.

I'm not aware of any specific tutorials, but I'll try to answer your
question and give a bit of an explanation.

First, if you're used to writing plenty of functions, you're about halfway
to OOP. The only real difference between what you do already (using
functions) and using classes is on a conceptual level. Classes can be
defined as a collection of data and functions that operate on that data.

Think back to a program that you've written with several related functions.
Perhaps you wrote something with several records that you may have stored in
a list or array or some such. So you may write a function called
get_new_record() that gets data for a record, either from the user or
somewhere else. Then you might have an update_record() function that
modifies a given record. And perhaps even a delete_record(). You could think
for a few minutes and come up with the rudimentary functions, I'm sure.

Now, instead of thinking about them as either lists inside a list or a
series of data elements stored in a list, imagine those records really are
"things" - objects that can stand alone. And you can tell that record that
you want to modify it, or you want it displayed some certain way, or any
number of things. The hardest part about OOP is deciding how much
responsibility an object really should have. Anyhow, that's all OOP is -
just taking the related functions that you would normally write and sticking
them inside a class. So instead of:

['somename', 'somedata', 'anothername', 'more data', 'no name', '']

you could have

[record1, record2, record3]

which you could modify the __repr__/__string__ methods to print out however
you want.

If you haven't made the link yet, GUIs tend to be objects because it's just
easier to think of them that way. If you have a (real life) bottle, you can
open the lid, close the lid, put stuff in, take it out, or throw it in the
garbage. It's a lot easier to think of a text entry box as something you can
put text in, or get text out of, or .

It's a different way of thinking about programming that begins feeling
entirely natural because we, as humans, are used to talking about things
that can do stuff and we can do stuff with. You might have hedge clippers
that have certain attributes - number and sharpness of blades, for instance.
They also have a function that you can .open() them and .close() them. But
if you close them with something inside they will .cut() the object you
place inside the clippers.

Alan Gauld (frequent contributor of this list) has a tutorial on OOP at
http://alan-g.me.uk/ that has some pretty solid examples about class-based
programming.

Of course, this discussion wouldn't be complete without telling you that it
is quite possible (using Tkinter especially) to actually adhere to
procedural programming. You could do something like this:

import Tkinter as tk

def buttonclicked():
print "Yay, you clicked me!"

root = tk.Tk()
button = tk.Button(root, text='Click me!', command=buttonclicked)
button.pack()

root.mainloop()

If you're more comfortable with procedural programming you can certainly do
it that way, but you'll probably find it a lot easier to spend some time
getting used to the concept of OOP and writing your GUI programs in a
class-based fashion.

Honestly it depends on how "pretty" you want it to look. Tkinter is the
ugliest GUI toolkit, but it's the easiest one to create simple GUIs.  To
create a window with a button with the text "hello world" that quits when
you push the button:

import Tkinter as tk

root = tk.Tk()
btn = tk.Button(root, text="Hello World", command=root.quit)
btn.pack()
root.mainloop()

And it's as simple as that. There are some fairly powerful widgets, but
nothing quite as advanced as you'll find in other frameworks. However, the
other frameworks do a have the benefit of a lot more power, so it really
comes down to what you want and what you need. If you need a simple GUI with
maybe a list or some text entry and some buttons, and maybe a menu, Tk is
the way to go.

If you want an advanced GUI with all sorts of pretty widgets and drawing
capabilities and bells and whistles, wx or GTK (my personal fave) are all
great options.

Of course, it's also my personal opinion that every python programmer should
learn Tkinter - it's a quick and easy way to throw up a GUI - so if you need
to just slap something together, it's right there. Plus it introduces you to
layout managers and callbacks, both of which are super useful programming
GUIs down the road.

Wayne

I spent some time a couple of years back looking at different GUI
builders for Python. Frankly I didn't like any of them. Nothing comes
close to the tools used in VisualBasic or Delphi etc.

Things may have improved in recent years and there are a few 
commercial
tools that I didn't look at but for my limited GUI programming needs I 
find

I'm just as well hand coding the GUI.

Just a personal view, others may differ. And if you intend to do a lot 
of
GUI work (especially if you get paid for it!)  then it may be worth 
paying for

something that really does a good job.

I have only ever used wx with the XRCed program, but I really like it.
Learning xrc is pretty straightforward, and there are some good
tutorials for it. It also has the advantage of keeping the code
generating your gui separate from your program, so code management is
easier. I have heard xrc/python compared to css/html regarding code
separation. For a really simple gui it is probably not too important,
but if you do larger projects later on it will probably make life
easier.

configure is better when you need to change more than one attribute of a

If you prefer you can use configure() all the time.

Hi Alan and Kent,

Thank you for helping me. This is a lot simpler than the solution I had in 
mind. The button names in my program always start with "button_", so I wanted 
to use locals() in a list comprehension to compile a list of the buttons. But 
then I'd still have the names and not the instances. 

But when is the configure() method more appropriate to change e.g. the button 
status?

[Tutor] GUI Buttons

I'm using Tkinter to program my very frist GUI.
Each button grays out after it has been used so the user knows what next 
steps to take.
Now I want to define a Reset button to 'ungray' all buttons 
(state='normal').

How can I programmatically create a list of all available buttons?


Just add your buttons to a list when you create them
Then in your reset method do

for button in ButtonList:
   button['state'] = NORMAL

The two most common Python GUI frameworks are Tkinter (in the
standard library) and wxPython - an add on. Both have a canvas
widget that will cater to your requirements fairly easily.

Another approach might be to investigate pygame since it excells
at graphics. There are a couple of other options too but I suspect
a simple canvas widget is nearly all you need and Tkinter or
wxPython will both procvidfe that.

There are several tutorials (and at least 1 book) for either option.

The GUI programming topic on my tutorial will give you the very
bare bones and show an example in both frameworks for
comparison.

I don't *think* the turtle module allows loading a jpg as a background, but
definitely allows you to draw a line.

Tkinter's canvas
PyGTK's DrawingArea
Pygame
pyglet
matplotlib
and even just using the PIL (Python Image(ing?) Library)

could all accomplish parts if not all of your goals.

I think I'm ready to start working with some simple graphic output.
Currently, I've got the basics of a Python program that calculates full
tours of a honeycomb structure, going through each cell exactly once. The
output from the program shows the paths as coordinates of each cell; what
I'd like to do is create a simple window that would show the tour in
graphical format, and using keystrokes to go through all of the tours that
have been collected. I'm already accounting for eliminating duplicates by

"northernmost" row of hexes, but the ending point to be any of the edge
hexes. I'm trying to identify duplicates by reflexive symmetries as well,
but I'd like to get the visualization component up first.

So why don't you put your menu in your game?

Consider the following:

# Lamegame.py - probably the lamest game ever!

print "Welcome to Lame Game!"
raw_input("Please type something and press enter: ")
print "You win!"

So there's a game. Now let's add a menu:

# lamegameimproved.py - the lamest game, now with a menu!

import sys

print "Welcome to Lame Game!"
print "\nMenu:\n"
print "(Q)uit"
print "(P)lay"
choice = raw_input("Your Choice? (P or Q): ")

if choice.lower() == 'q':
sys.exit(0)
elif choice.lower() == 'p':
# add original code here

See? Quite simple. Even with pygame it shouldn't be a whole lot more complex
than that. And that's really the most simple example I could think of and
it's really not very good. For instance you could put the original code into
a "game" function and then call it if the choice was P.

Wayne

So you have a pygame window that is just a menu? and when you select  it will try to run another python script? Your description of your

advice.



When you say "menu" and "different window" that could mean a host of things. If

Readable doesn't mean it have to be colored and line numbered, although
this is more readable than the previous one -- at least on a newsreader
that supports HTML -- it's better to keep messages in plain text (i.e.
not only unformatted text but change the newsreader's settings to pure,
plain text)

All right to the problem, the problem is not related to pygame at all;
it's in your subprocess.Popen() call. The traceback says that
subprocess.Popen cannot find the executable/script that would be run.

A quick look at the traceback:
subprocess.Popen(["D-Day", "Destruction.py"])

That line is executing an executable/script named "D-Day" and pass an
argument "Destruction.py" to it. Probably not something you wanted to
do. What you want to do is something like:

subprocess.Popen(["D-Day\Destruction.py"])

or perhaps:
subprocess.Popen(["python", "D-Day\Destruction.py"])

depending on whether the file association is setup correctly and whether
the shell's search path is set to search python's install directory.

As far as I can tell, since your error formatting was lost, is that Popen
can't find the the file.

The other problem is that what you're thinking of really makes no sense.
Pygame doesn't need (and shouldn't) run a program "inside" the window. You
should have all of your game processes available to the main program and
when you want to start the game it should just be a part of it - not a
subprocess.

Have you tried asking on the PyGame forums/mailing lists? 
I'm sure such things exist. This forum is for general Ptython 
programming, specifically for learners. While we are happy 
to try to help I don't know that we have many pygame experts 
here.


The second thing I am trying to do is initiate my game also 
made in pygame to start off a button that a programmed 
called Destruction.py


I have no idea how pygame works for buildng GUIs but usually 
you tie a button to a python function not a program. Are you 
sure that is not what you should be doing?


The error was what had happened was that the module 
i made for pygame is not initiating my game properly 


The other error you made was posting unreadable emails to 
the list. We are keen to help where we can but don't force 
us to manually unpick a steam of text. Please senmd plain text 
- your email system should have a setting to allow that.

I dont know what you are using for email but it seems to be
scrambling your messages. I assume what you want is:


one button that initiates the Team.py file
one button that links to read a hs.txt
one button that initiates 800x532 png image in a new window
one button that quits pygame window


Now, I'm no expert on pygame but can you tell us more
specifically what you are finding so hard about putting
your 4 buttons on the image?

It is creating the button objects or is it linking them to  the functions?
Or is it displaying them using the image?

The more specific your question the more likely that someone
will answer it.

Re: [Tutor] GUI with Designer

[Chris Hengge]

Well, I use SPE which comes with wxGlade and XRC. For the small amount of gui I've done with python I think SPE offers the best IDE coder experience (coming from a VS world). The tools make sense to me.wxGlade is a GUI designer written in Python with the popular GUI toolkit 
wxPython,
that helps you create wxWidgets/wxPython user interfaces. At the moment
it can generate Python, C++, Perl and XRC (wxWidgets' XML resources)
code.XRC(wxWidgets' XML resources) is nice because it allows you to abstract your interface design (think of any program that uses XML to format skins). Overall, I think everyone using python should give SPE a try, even without gui programming its a great tool for writing code. It's free, and written in python using wxPython.. Stani (the Dev) is a great person for helping out with questions on using his package, he puts out regular updates and fixes. He's got some help from a few other people so its packaged in .exe, .rpm and standalone .zip formats. It's also on the standard repo's for Ubuntu. 
If you like it, be kind and toss the guy a few bucks for his efforts. If you do, you will get your name mentioned on the SPE news page and get a nice copy of his user manual (pdf).If you want to know more about SPE, check out:

I am wanting to get into some GUI coding with Python and have heard about PyQT and wxPython. Now I am definately not looking for some type of holy war but can anyone give me a good reason to pick one over the other.

 
Also I would like to have a designer with it or a seperate designer that could be used with either. I plan on coding in Windows XP.

Yep, yep.
I confess, I didn't look too closely at that, and I guess I heard one 
should use backslashes whenever a command goes to a new line,
and I assumed it was always true, and never tried without them!
You're right, of course, John, and I apologize to the OP.  Alan had the 
correct answer to the problem.
Listboxes don't take a command argument.

Hope that helps!

Because whitespace is important in python,
you can't arbitrarily put newlines into your text.
Your program is getting confused because it doesn't know what ',

Try putting a '\' before your newlines.

This is like asking which programming language is best,
or which editor/IDE to use. Everyone has their own favourite.

My personal view is:

If you have used any GUI before then use wxPython - it looks
better and has more widgets.

But if you have never used a GUI toolkit before use Tkinter,
its easier to learn (and use IMHO) and has much more documentation.
Once you know Tkinter moving to wxPythobn is relatively
straightforward because the underlying prionciples of all GUIs
are the same.

And of course Tkinter is based on Tk whicgh is also available
for Perl and Tcl/Tk and Scheme. So its worth learning for its
portability too.

You can start with my GUI intro topic which teahches Tkinter
but finishes with a wxPython example so you can quickly switch
if you want to.

BTW I strongly recommend startiung out with the raw toolkit
and manual programming to understand how itall hangs
together. Later you can pick up a GUI Builder like
Glade/Blackadder/SpecTix etc. But its best to understand
what these tools are doing first IMHO...

Tkinter is (IMO) easier to learn.  In particular, check out "Thinking
in Tkinter" (google for it); it's an excellent way to learn Tkinter.

Tkinter is also very basic.  wx has many more widgets and controls
available.  wx also looks a lot better.  But the documentation for wx
isn't very good.  wxpython has been evolving -- it started out as a
direct python port of some C++ libraries, and
has been becoming more pythonic as time goes by.  So if you go looking
for example code, you could find something written in the modern,
pythonic style, or you could get something written in the traditional,
C++ style.  Until you learn to recognise the latter and transform it
to the former, you may find learning from the web difficult.

Both Tkinter and wxpython should work across all platforms.

However, you really should spend a few bucks buying the recently 
published "wxPython In Action" book by Noel Rappin and Robin Dunn (the 
designer of wxPython).  It will save you lots of time.

You also might like to check out wxGlade which is a FOSS GUI designer 
for wxPython.  It will play happily with your chosen editor.  I have 
tried most of the available GUI designers and liked this one the best 
although is is a little brittle.

http://wxglade.sourceforge.net/

Another _very_ promising system is Dabo but this is not quite ready for 
prime-time.  I think that Dabo is going to be a dynamite system for 
building GUI db apps.

Re: [Tutor] GUI

Tkinter is simpler to use, wxPython is far more powerful but a bit
harder to learn. It's based on the C++ library wxWidgets, and
sometimes the abstraction leaks a bit, but this is just my opinion.

Check out pythoncard though, it simplifies wx development
dramatically; even has a drag and drop interface; but you can still
use wxPython method calls and objects directly if Pythoncard doesn't
do what you want.

Re: [Tutor] GUI

[Liam Clarke]

Hmm? How so? I'm using a whole lot of raw wxPython mixed with
Pythoncard for a project, and the entire process sits at 7Mb RAM usage
idle. WinXP btw.

Considering my small command line appns to start/stop Windows services
written in C use just over 1Mb, 7Mb isn't overly bad.

The other good thing about wxPython is stuff like Pythoncard and Wax,
although development on Pythoncard seems to have slowed right down,
Kevin Altis got busy, I guess; Wax is nice looking but... not very
well documented... It's great being able to use Pythoncard for the not
overly complicated stuff, but with the wxPython still lurking beneath
the surface.

It's a dual license. If you use Qt in non-commercial software, the GPL
applies and you pay no licensing fees. If you use Qt in commercial
software, licensing fees are due to TrollTech.

Any reason why you must use PyQt?

Not that it's a bad toolkit but there is less expertise in using 
it so unless you already use it from another language 
- like C++ - its going to be a lot harder to learn than Tkinter 
or wxPython which are the two most commonly used GUI 
tookits.

Both Tkinter and wxPython are free, Tkinter comes with Python, 
wxPython is a searate download. wxPython tends to look nicer 
and has some fancier widgets. You pays yer money etc...

If you just wqant to wrap up some scropts Tkinter is probably slightly
easier to use (IMHO), but it doesn't look as nice.

wxPython looks better and is only slightly more complex. But it does have
a couple of GUI builder options in the shape of Glade and PythonCard.
If you want to build full blown GUI apps then WxPython is the way to go.

But search the archives, this gets debated at least every 6 months or so :-)

I have only used Tkinter so far, so I cannot say much about wx.

Tkinter's biggest disadvantage is that some advanced widgets are missing, like
a spreadsheet widget or a html viewer. There is also no built-in drag&drop 
support.
A lot of these things are available by installing extension modules, though.

If you don't need any of these Tkinter is worth a try; it is well documented, 
stable
and easy to learn, and the biggest advantage over other toolits, it is included 
in
the standard python distribution.

If you want to use Tkinter you should also have a look at Tix, which is now 
included
in python's windows installer (and also in any recent linux distro) and which
adds a lot of nice extra widgets to Tkinter, like Combobox and Tree widget.

A good place to find out more about Tkinter is the wiki: 
.

I hope this helps

Michael

I am developing applications that need to run without work on both windows and

I have been looking at wxpython and tkinter.
