Subject: [Tkinter-discuss] ANN: WCK for Tkinter 1.1 alpha 1 (september 5,
	2004)
Message-ID: <chf6ri$pc1$1@sea.gmane.org>

The Widget Construction Kit (WCK) is an extension API that allows
you to implement custom widgets in pure Python.  The WCK can be
(and is being) used for everything from light-weight display widgets
to full-blown editor frameworks.

The Tkinter3000 implementation of the WCK supports all recent
versions of Python and Tk/Tkinter.

The 1.1 alpha release adds the ability to change widget controllers,
and also adds an experimental native graphics driver for Windows.

I am parsing an XML file using xml.sax and xml.sax.handler
But the program does not run succesfully as there are some special characters in the XML file. Where can be the problem? How can I find the special characters and escape them. Can I convert them into Unicode? Can anybody point to a good document? Thanks alot...

		handler = docHandler()
		parser.setContentHandler(handler)
		parser.parse(doccorpus)
		print 'file parsed successfully'
	except:
		print position

this is a Tkinter mailing list, not an XML mailing list.  post your question
to comp.lang.python, or the Python xml-sig mailing list.

I haven't posted to this news group and I usually look all over for
other options rather than bother other people.  I have been looking
everywhere for any information on how to install the link between Python
1.6 (unfortunately) and Tcl on SCO Openserver Unix (5.05 version).  I
see all the makefile information in the python library, but it seems to
be missing a library reference.  I down loaded the files from SCO's
skunkware section.  Silly of me to think it would actually work.  Also
tried on Unixware as well.  Has anyone had any experience with SCO?  I
thank you in advance for any help, even if there is not help.  I do have
2.2 source, but it has problems compiling on Unixware. Thanks.

you need the right Tcl and Tk libraries; I don't recall what version 1.6 used,
but 8.0 or 8.1 should probably work.  you can get 8.0 and newer here:

    http://www.tcl.tk/software/tcltk/choose.html

you can probably figure out the preferred version by looking at the README
and/or the Modules/Setup file.

if you have the libraries, make sure that the Setup file points to the right locations.

however, Python 1.6 is a totally broken release (it's basically an early 2.0 alpha,
released for contractual reasons). if newer versions don't work for you, you're
probably better off with 1.5.2 (which works with Tcl/Tk 8.0).

    http://www.python.org/1.5/

you could also try to build 2.1 or 2.0

    http://www.python.org/2.1.3/

I looked again.  I have version 2.2 on Unixware and 1.5.2 on the
openserver.  I also have TK 8.0pw and 8.1.1 installed on the openserver.
Apparently the total source isn't there from SCO's distro for linking in
TK as I don't see any references to making tk in the module libraries.
I'll put the 'real' source for 2.2 on my openserver.  I've tried to link
the 2.2 from source and run into problems.  Also the version of TCL on
sco is their own special version that can do gui or ncurses depending on
if DISPLAY is defined.  Has anyone used that?  I'm sure it's not
compatible probably.  Anyway, I'll uninstall all of that and try using
your source to set up one that works. If I still have trouble, you may
hear from me again.  I hope that's alright.  Thanks for the quick reply.

I'd like to be able to change font size in my Tkinter app.   I've attached a
sample app below that allow for this. Problem is, the method is run when the
menus are drawn, but doesn't run afterward.  How do I stop the font sizes from
changing when the app is started up?  One way might be a lambda function, but is
there any other cleaner solution? Thanks!

I found out how to stop my font-changing method to be called when I draw the
menus.  I simply created a lambda function to pass the new font size to
font-changing method.  

I've also confirmed that the method does actually change the default font size
for my application.  

Now my only problem is how to get everything to be redrawn, so that the new font
size becomes visible.  Any help is appreciated.  The latest version of my test
app is below.

thanks
Stewart

hi again:

Giving further thought to the problem of how to have a live change of font sizes
in a Tkinter app, I tried using a Tkinter.StringVar.  The modified test app is
below.  It works, as least insofar as it correctly gets and sets the var, but I
still see any visible changes. Somehow I need to force a re-draw of the entire
app. any ideas?

I guess if this is not possible, I could simply write out the new font size to a
.ini file, ask the user to restart the app, and read that .ini file when I start
up. Seems kinda kludgy, though.

Hi Stewart,

maybe the easiest would be to put all the widgets that use the font in a list and then do something like:

for widget in widgetlist:
    widget.configure(font=newFont)

when the user changes the font.

I think the usual way to do this is to use an option database which allows to override default tk options
like fonts and colors (in case you want to change the default font for the whole app). Entries in an option database
look like this:

*font : Helvetica -12
*Entry*background : white
*Listbox*background : white
*Listbox*exportSelection : 0
*selectBackground : #a0a
*selectForeground : white
*Scrollbar*Width : 12

If you store this in a file "optionDB" in the application's directory you can access the options with option_readfile():

root = Tk()
root.option_readfile(sys.path[0]+"/optionDB")

The options apply to all children of root that are created after option_readfile() is called, however
I don't think it's possible to apply changes to the option database to widgets that already exist this way.

I hope this helps

Michael

I want to change all my menu entries to use the new font.  But,I don't see how
to get the right name for those items to use in the list since each menu entry
doesn't have a discrete object name, like say a button would
(btn=Tkinter.Button, so you could have widgetlist=[btn,lbl,btn2].  I read
something about using component() to achieve this, but the exact implementation
escapes me - the example I saw related to notebook tabs rather than menu entries.

thanks for this useful detail.   I'll give it a try on Monday.  I did try a
similar idea, putting the current font name into another module which I called
basefont.py.  I built a test app and was able to change the font this way (the
user has to quit and restart the app, but that's okay).   The strange thing is,
when I copy the methods into my real app, it doesn't work due to a scoping
problem in the lambda function I use. I'll post the details on that on Monday. 

thanks
Stewart

You could try this little snippet...:

 from Tkinter import *

class WidgetWalker:
     def __init__(self, parent):
         self.parent = parent

     def __call__(self):
         self.walk(self.parent)

     def update(self, widget):
         try:
             widget["font"] = "Helvetica 18"
         except:
             pass

         try:
             widget["fg"] = "pink"
         except:
             pass

     def walk(self, top):
         self.update(top)
         for child in top.children.values():
             self.walk(child)




if __name__=="__main__":
     root = Tk()
     f = Frame(root)
     l = Label(f, text="Label")
     l.pack()
     b = Button(f, text="Button", command=WidgetWalker(root))
     b.pack()
     inf = Frame(f)
     l2 = Label(inf, text="Label 2")
     l2.pack()
     inf2 = Frame(inf)
     l3 = Label(inf2, text="Label 3")
     l3.pack()
     inf2.pack()
     inf.pack()
     f.pack()
     root.mainloop()


It relys on the children dictionary every Tkinter widget has.


Cheers
Martin

You'll have to use the "entryconfigure" method of the menu object.

Here's a program that changes the font of all entries of a menu:

import Tkinter

def set_menu_font(m, f):
    for i in range(m.index("end") + 1):
        t = m.type(i)
        if t in ("tearoff", "separator"): continue  # no font= option
        m.entryconfigure(i, font=f)

t = Tkinter.Tk()
m = Tkinter.Menu(t)
t.configure(menu=m)
m.insert_cascade("end", label="File", underline=0)
m.insert_cascade("end", label="Edit", underline=0)
m.insert_cascade("end", label="Help", underline=0)

b = Tkinter.Button(t, command=lambda: set_menu_font(m, ("Helvetica", 24)),
                    text="Font 1")
c = Tkinter.Button(t, command=lambda: set_menu_font(m, ("Courier", 12)),
                    text="Font 2")
b.pack(side="left")
c.pack(side="left")
t.mainloop()

I posted a question on this topic a few days, and got three interesting, and
quite varied, approaches to a solution from Jeff Epler, Martin Franklin and
Michael Lange.  One of the approaches apparently works under Linux, but wouldn't
work (for me) under Windows, at least not yet.  I had the most success adopting
Martin's approach, which is contained in modified form in the code sample below.
Note that my sample app makes use of Pmw, which you can get from
http://pmw.sf.net.   My app allows the user to change the font face or the font
colour interactively.  I leave it as an exercise for the reader to be able to
change the font face as well (e.g. from Helvetica to Roman or Courier).  

This list is invaluable for me, because I'm coming across material that seems to
be absent from any of the information sources I have so far for Tkinter.  

thanks again!

cheers
Stewart

Stewart,

I got your code running good work!  However it doesn't update the fonts
of the menu items.

At least not on my Windows machine - Win 2000 Python 2.3.3

For that I had to add some of Jeffs code see below

The best thanks, folks, is to memorialize discoveries and creations in
the Tkinter Wiki <URL: http://tkinter.unpythonic.net/wiki/RecentChanges >
associated with this mailing list.  While I make occasional abortive
efforts to transfer knowledge there, it'll work a WHOLE lot better when 
several more of us are doing so.

Subject: Re: How to change font sizes in a Tkinter app?

My menu manpage says this about menus on Windows:
       When  Tk  sees  a System menu on Windows, its items are appended to the
       system menu that the menubar is attached to. This menu has an icon rep-
       resenting  a  spacebar,  and can be invoked with the mouse or by typing
       Alt+Spacebar.  Due to limitations in the Windows API, any font changes,
       colors,  images, bitmaps, or tearoff images will not appear in the sys-
       tem menu.
maybe this limitation applies to all menus, or the initial -font
setting cannot change, or there is some OS-specific limitation that is
not documented.  This is the price you pay for a native-looking menu
on Windows...

I just ran this on Windows XP SP2, Python 2.3, Tk 8.4 and indeed my
program doesn't work---the font doesn't change size.  But neither does
setting a font in the first place.  When the menu with entry fonts set
is posted by a menubutton, I get that font on Windows.
    mb = Tkinter.Menubutton(t, text="Menu")
    mbm = Tkinter.Menu(mb)
    mbm.insert_cascade("end", label="File", underline=0, font=("Helvetica", 24))
    mbm.insert_cascade("end", label="Edit", underline=0)
    mbm.insert_cascade("end", label="Help", underline=0)
    mb.configure(menu=mbm)
    mb.pack(side="left")

So I guess that items on the main menu bar have the same caveat as those
on the System menu.  It's unfortunate that this isn't documented by the
Tk folks.

In fact, I've used this as an excuse to create the page
    http://tkinter.unpythonic.net/wiki/Widgets/Menu
Feel free to add to it if you have more to say!

Above does work - but I thought we were supposed to move away from  
Menubutton's

(Can't remember where I read that though)

Sorry Jeff not sure I follow are you saying this :

import Tkinter

t = Tkinter.Tk()
mb = Tkinter.Menu(t)
mbm = Tkinter.Menu(mb)
mbm.insert_cascade("end", label="File", underline=0, font=("Helvetica",  
24))
mbm.insert_cascade("end", label="Edit", underline=0)
mbm.insert_cascade("end", label="Help", underline=0)
t["menu"] = mb

mb.add_cascade(menu=mbm, label="Menu")
t.mainloop()


does not show a different font on your Windows system?

I confess I'm confused by that as well.   When I check your code sample, I see
that the 'File' menu item is indeed in a larger font size.   And indeed, if I
modify that sample (see below) to add a font specification for every item in the
menu, they all take a new font - except for the top-level menu item ("Menu").
Perhaps that's what Jeff means. 

With the app that I posted a little while ago, every level of my menubar takes a
new font *except* for the system menu - but since the system menu is not
normally used in running an app, I don't mind that.

I don't have a Windows machine to test on at the moment, and it's
possible that I botched my test code in the message.  What I
observed was that
* If a menu is the -menu of a Toplevel, font settings are ignored on
  Windows
* If a menu is the -menu of a Menubutton, font settings are obeyed
  on Windows

I did not test the case for "cascade"s of the menubar, but I suspect
that *will* show the changed font on Windows.

Now this gets curioser and curioser.  When I add your code in, the top-level
menu entries (File, Options) no longer change fonts. (Maybe I copied or indented
your code wrong?).  If I leave my test app as-is, all of the menu items' fonts
change.  I'll attach my app as an attachment so it retains its formatting,
though a text version is below, for those that don't get attachments.  My code
for the update method comes first, with yours as a new method update2; switching
the names will run your version instead of mine.   Do you get the same results
as I do when you run this app?

BTW I'm running Win2k and Python 2.3.4, nearly the same configuration as yours.

Stewart,

Unchanged your code does update the font of the Menu-bars items
(I.E The words "File" + "Options") but not the menu items.

I just had a thought perhaps it's a different Pmw version..... ahhh
yes I've got an old 0.8.3 Pmw Bundle in my dumping ground directory!
This version of Pmw uses Menubuttons (under the covers|) perhaps the
latest is different...

I will need to download and install (should have done that years ago)

Incidentally I am also using Python 2.3.4 - I Must have upgraded in my
sleep ;-)

Will let you know after the upgrade...

Cheers,
Martin.

And on that note I just updated the Widgets Page to include a mention of  
the
new widgets in Tk 8.4, now that I have broadband at home I hope to be able  
to provide more information to the Wiki :-)

I also added a short note regarding TkTable


As for the recipe (WidgetWalker) where abouts should it go - It ain't a
new Widget;-)

Well now I'm stumped... really running your code unchanged with Python  
2.3.4
on Windows 2000 with Pmw 1.2 it only changes the Toplevel Menu Font
"File" and "Options" none of the menu items change font at all

Then, again unchanged, using update2 method does the oposite - it changes
the fonts of all the menu items but not the toplevel menu's themselves


Now I put the update code into the update2 method (as I think it was in
my earlier reply) and it changes all fonts for all menu's and all menu
items.


Lets call it update3 ;-)

     def update3(self, widget):
         try:
             widget["font"] = self.newFont[self.size]
         except:
             pass
         try:
             # for each menu item try setting the font
             for i in range(widget.index("end") + 1):
                 t = widget.type(i)
                 ## unless it's a tearoff or separator
                 if t in ("tearoff", "separator"):
                     continue
                 widget.entryconfigure(i, font=self.newFont[self.size])
         except:
             pass



I had a quick look at the Pmw source code for it's MenuBar and it still
uses Menubutton under the covers, however I noticed a MainMenuBar mega
widget that does not...  I think part of all the confusion lies with
the Menubutton vs Menu widget in Tkinter...  As I said in an earlier
post I thought Menubutton was depricated - I can't remember when or
where I read that - I thought it was in Guido's old tkinter demo code
that used to ship with the python source code (anyone got an old distro?)
but my memory's not what it used to be (2 kids will do that to a man)


Clear as mud ;-)

Cheers
Martin

Bingo!  Jeff has been right all along - I just wouldn't listen ;-)

If the Toplevel menu is a Menu object then the font option is ignored
on windows it's items font may be set though.

If however Menubutton is used then the font option is honoured.

Pmw.MenuBar uses Menubutton


> post I thought Menubutton was depricated - I can't remember when or

As for that I guess my brain really is fried!

[snip useless babble from myself]


So Stewart what was the question again? ;-)

I'll bet you can't find this kind of useful detail in most of the tutorials. 
And it's exactly those little details that trip you up when attempting something
new.  Which is why a recipe collection of how-tos for typical tasks is a good idea.

Thanks Jeff,  Done.

I also attempted to re-word you explanation of the whole Menu episode ;-)
I added a ExampleCompoundButton and wanted to include an image.  I could
like from my own website but I guess it would be faster to have a local  
link.

In fact I did want to add images of the new 8.4 widgets too.

Message-ID: <20040920.193900.10145.187701@webmail07.nyc.untd.com>


Hello everyone.  I have an issue that is causing me many anxious moments.  So, at long last, I feel I need to refer to the experts.

I am trying to create a Pmw.NoteBook instance that the user names as he/she creates it.  Specifically, I am trying to enable the user to name the NoteBook instance in its own entryfield, similar to creating a new Tree node in Windows Explorer or a new Windows folder or shortcut icon, for example.  Secondly, I am having a hard time associating the input string name with the NoteBook instance.  Unfortunately, I have gone through many cycles trying to make things work, and the code has broken each time, so I have included just the base code that (almost) works.  Any ideas on this one?

Thanking you in advance,


Christopher Nethery

Hi Chris,

Each notebook "page" is created using an instance of tkinter.Frame and
tkinter.Button (according to the reference page for NoteBook).

So your first problem would be that "buttons" can't be typed into - you need
to replace the Button component of each page with an EntryField -> which
changes to an grayed out entryfield (or something similar) once the user has
supplied the name. 

So (re)searching back into the class hierachy reveals that classes derived
from Pmw.MegaArchType's can have the "default" components from which they
are built "overridden" (refer to the "pyclass component option" section of
Pmw.MegaArchType). There are some "clues" here as to what you might have to
do - perhaps examine the code of NoteBook and then create a class that
inherits from NoteBook - which uses an entry widget of some form in the
construction of a new page and then either changes it to "Button" or "greys"
it out so it can't be changed after the user has supplied the name.
Certainly that is how I would proceed - inherit from NoteBook and create a
new class that offers this "feature" - you'll then have a nice re-usable
component that you could share with the rest of us :-) 

At first glance it is a non-trivial exercise i.e. more time than I have left
in my lunch hour to nut this one out :-) So goodluck with your journey.

Peter

Peter,

Thank you for some direction on this one.  And, you're right, this will make a great GUI enhancement, once it's completed.  I'd be happy to post the finished product in the forum, once finished, although I imagine I may need some more pointers here and there until it's complete.

Chris,

I snipped all your code sorry but here is my first stab at the problem you  
outlined



 from Tkinter import *
import Pmw



class MegaNoteBook(Frame):
     def __init__(self, parent):
         Frame.__init__(self)

         addButton = Button(self, text="Add Page", command=self.addPage)
         addButton.pack()
         self.noteBook = Pmw.NoteBook(self)
         self.noteBook.pack(fill="both", expand="yes")


     def addPage(self):
         ## method to add a page to the notebook - I need to change the  
'button' tab
         ## property of the nbotebook
         thisPage = self.noteBook.add("NewPage")
         ## find the button widget for this page bind to
         thisTab = self.noteBook.tab("NewPage")
         ##it's text put up an entry field so the user can edit it
         self.update()
         x, y = thisTab.winfo_rootx(), thisTab.winfo_rooty()
         entry = MegaEntryField(x, y, self)

     def setNewPageName(self, name):
         print name

class MegaEntryField(Toplevel):
     def __init__(self, topx, topy, megaNoteBook):
         Toplevel.__init__(self)
         self.overrideredirect(True)
         self.geometry("+%d+%d" %(topx, topy))
         self.megaNoteBook = megaNoteBook
         self.entry = Pmw.EntryField(self, entry_width = 7,  
command=self.renamePage)
         self.entry.setentry("NewPage")
         self.entry.pack() ## ?? should size accordingly

     def renamePage(self):
         name = self.entry.get()
         self.megaNoteBook.setNewPageName(name)
         self.withdraw()

Thanks Chris,


Just a few words of warning regarding the Pmw.NoteBook
it keeps track of its pages using both a list and dictionary
I know from past experience changing the name of a NoteBook
page causes a lot of headaches, I think (although I can't find
the code) I ended up keeping track of 'new vs old' page names
in my own code.


Cheers
Martin

Subject: [Tkinter-discuss] py2exe and Pmw - help please
Message-ID: <C59AEFCA2D33284B8EE3C0A8C8C9004A10848D@kiwi>


I'm sure you've had this query before, and I did try lots of googling,
but I still haven't got there...

I have a program which uses Tkinter and Pmw, and it works fine in the
interpreter.  I have used py2exe
succesfully on non-gui programs.  And I have created Pmw.py using
bundlepmw.py.  But, wherever I put
Pmw.py (and PmwBlt.py and PmwColor.py), I get the same message on
running the executable as if I hadn'd
bothered hooking up Pmw at all:

Traceback (most recent call last):
  File "newproj.py", line 21, in ?
  File "Pmw\__init__.pyc", line 28, in ?
WindowsError: [Errno 3] The system cannot find the path specified:
'C:\\data\\Software\\Python\\newproj\\v2_1\\dist\\library.zip\\Pmw/*.*'

So, where do I put the Pmw files when I use py2exe?  And also, once I've
made my executable, what do I do
with all the dll, pyd, and zip files when I use my executable on another
computer?

I'm using Python 2.3 and Windows XP for the compilation, and various
flavours of Windows for running the
executable.  And here's my setup.py:

#--------------
from distutils.core import setup
import py2exe

import sys
sys.argv.append("py2exe") #Avoids having to use the command line

setup(
    version = "2.1",
    description = "Creates default file structures for new
projects/tenders",
    name = "newproj",

    ## packages = ["Pmw"],

    # targets to build
    windows = ["newproj.py"],
    )
#--------------

Any help would be most welcome.
David

Subject: [Tkinter-discuss] passing parameters to a lambda function in
	Tkinter menubar
Message-ID: <1096071967.4154bb1f13449@midtoad.homelinux.org>



Here's a problem I keep running into. It occurs when I try to pass parameters to
a menubar item's command property using a lambda function. Probably it's a
scoping problem, but I don't see how to resolve it (except not to pass parameters). 

Essentially the problem is this: if you simply call a method as the command
callback when you are creating a GUI, that command will be executed right away
when the GUI is drawn - at least, if you pass that method any arguments.  

One way to get around this is not pass arguments to the callback methods.  I
thought another way might be to use a lambda function, and pass it the
arguments. That works if the lambda calls another class, but if it calls a
method in the same class, I get name errors. 

In the attached mini-app, which uses Pmw, the File > Close menu selection uses a
lambda function that passes a parameter to another class with a __call__ method.
It works properly.

However, the Options > Set size To menu choice, which uses a lambda function to
pass the size string to a setFont method, does not work.  It looks as though the
lambda function doesn't know it's part of the Demo class, so it can't find the
self.setFont method.  If I replace 'self' with the name of the class, Demo, I
instead get an error saying 'unbound method must be called with class instance
1st argument'.

Can anyone shed any light on how make this latter method work? It would greatly
clean up my app.

thanks
Stewart

the lambda isn't part of the class, it's a function object.  to be able to
find the right self, bind it just like you bind the size value.

            menuBar.addmenuitem('Size', 'command', 'Set size to ' + size,
                                command = lambda self=self, ss=size: self.setFont(ss),
                                font=self.font,
                                label = size)

according to the "functions are cheap, lambdas are hard to read" rule,
this is better written as:

            def setfontsize(self=self, size=size):
                self.setFont(size)
            menuBar.addmenuitem('Size', 'command', 'Set size to ' + size,

doh!  That seems so obvious when you explain it.  Naturally, though, that
concept doesn't appear in any documentation I've read about lambda functions.

This is great! It allows the code to be read more easily, while still allowing
me to pass arguments through the callback.  This great little tip should be on
the tkinter wiki site (note to self).

I think you're thinking of this in terms of syntactic scope.  While
that's a healthy instinct, the approach I find most successful in
explaining Tkinter's event orientation is to teach developers to 
categorize variables in terms of "define-time" (or "bind-time") vs.
"run-time" ("execute-time" or "use-time" or ...).  IT CAN EASILY 
HAPPEN THAT ONE BINDING INCLUDES BOTH.  I'm too weary now to write
this up for the Wiki.  I invite you to do so, though.

Subject: [Tkinter-discuss] Tkinter screen saver?
Message-ID: <twig.1096170347.39245@cs.brynmawr.edu>

Tkinter discussion,

I'm wondering if I can get Tkinter to make a window that covers the whole
screen so that we can have a Python-based screen saver?

It looks like I can't move a Tkinter window so that the title bar doesn't
show. For example, I see that Tkinter cleverly assumes that if I set a window
geometry with negative x and/or y, it positions it from the bottom/right. But
if I keep making the negative number bigger, I can get it to go off of the top
of the window; I always get the title bar on the screen. Maybe this is my
window manager's fault?

Also, I can't make a window bigger than the screen size minus the width of the
borders.

Anyone have any ideas on getting something that approximates a canvas that
covers the whole screen in Python? Thanks for any pointers,

-Doug

try this:

from Tkinter import *

root = Tk()
root.config(bg="red")

w, h = root.winfo_screenwidth(), root.winfo_screenheight()
root.overrideredirect(1)
root.geometry("%dx%d+0+0" % (w, h))

root.mainloop()

</F>

Great! Had missed "overrideredirect". For anyone that is interested, 
this project is really a program that runs on a hall computer LCD 
display. It will no doubt change (become more dynamic/customizable), but 
it currently displays images from a directory and has a ticker that runs 
across the bottom. You can see the current source at:

http://bubo.brynmawr.edu/cgi-bin/viewcvs.cgi/DisplayProject/display.py?rev=HEAD&content-type=text/vnd.viewcvs-markup

Suggestions/comments always welcome.

Thanks again,

-Doug

I guess one question would be how do you import Pmw in your application.
I have created a Tkinter + Pmw py2exe application I didn't do anything
special.  I too had a Pmw.py and PmwColor.py bundle both these files are
are in a sub-directory (and package) called Pmw, this package also has
a __init__.py file.  The contents of the __init__.py file are:-


# __init__.py Pmw Package

 from Pmw import *


The setup.py I used looked like this:-


# setup.py
 from distutils.core import setup
import py2exe

setup(windows=["MyApplication.pyw"])


And it just worked....

Inside the main application module I import Pmw like so:

import Pmw


So again nothing special....

Sorry I can't be of more help....

Thanks Martin, that worked.  In fact I had been here before, amongst
other variations.  But the trick was to
delete the "dist" folder before running setup.py.

I need to be able to enable or disable menus in a Tkinter app that uses a Pmw
menubar.  I easily found a sample app (first sample below) that shows how to
disable a Tkinter menubar, but I'm using the Pmw widget set, so this sample
won't work as listed.  So I went looking for clues, and it took quite a while to
find them!  Eventually I found something, and with some experimentation, got it
to work. My sample app is attached (second sample below).  

The trick is to reference menu entries by an index number (0 for the first
entry, 1 for the second, etc.).  You can also enable or disable cascading menus
this way (though I haven't tried disabling individual entries in a cascaded
menu).  The non-obvious part is that if you want to disable, say, the 'Options'
menu, you have to enter 'Options-menu' in the following line:
self.menuBar.component('Options-menu').entryconfig(0,state='disabled')

Hope this helps someone!

cheers
Stewart

Hi All,

		   if self.showletter()=='complete':
                    return 'break' # or just return?

Here is the problem...   self.showletter()
should return 'complete' if the word is
complete so this function does not continue

		   return 'complete'


Above neds to resurn 'complete' (or somthing)
to calling function

If anyone is interested in having this code drop me a line...

	Failed!"
Message-ID: <DFCB7C708B1AA94FABFBF6E1F7E9845474A23C@iiex2ku01.agere.com>

Hi : 
I am facing the following problem in the interaction between Python,
Tkinter and TCL. Can anyone please give me some ideas on how to solve it
? 
I have a hardware, which can be controlled using TCL commands. I am
writing a python script which calls the relavant TCL commands and in
turn controls the hardware. I am using Tkinter as an interface to the
Python and TCL scripts. 
The python script runs very well, without any problem. But, at the end
of the run, a window pops up with an error message. The message is as
follows: 
"Debug Assertion Failed !!! 
Program : F\Python23\python.exe 
File : dbgheap.c 
Line : 1044 
Expression : _CrtIsValidHeapPointer(pUserData)..." 
My Python script looks something like this : 
import Tkinter 
root = Tkinter.Tk() 
root.tk.eval('source tcl_file.tcl') 
userName = 'abc' 
root.tk.eval('Init_hardware %s' %(userName)) 
My TCL functions : 
proc Init_hardware {userName} { 
load "hardware_name.dll" hardware_name_pkg 
# This line actually initializes the hardware 
hardware_name init -user userName 
} 
Any ideas will be highly appreciated. 
Thanks in advance.

This is not necessarily a Tk bug.  This message is a low-level message
from the Windows C runtime. 

You can find nearly 400 references to this message by searching google
    http://www.google.com/search?q=_CrtIsValidHeapPointer+dbgheap.c
    http://groups.google.com/groups?q=_CrtIsValidHeapPointer+dbgheap.c
Most of the messages are unrelated to Python or Tk.  Some of the messages
imply it's a DLL or MSVC++ version mismatch.  Others imply it's an
application or library bug (such as a double free or use-after-free bug).
It's possible that this bug is in your "hardware_name.dll".

The bug probably shows up at shutdown because at this time lots of memory
is freed, and if the memory is a double-free type error this is a very
likely time for it to appear.

If you can recreate this problem without using an extra dll, or with a
simple DLL that is "clearly correct", we'd be interested in hearing
more.  If not, there's little we can do, because it strongly implies
that the bug is in "hardware_name.dll".
