Subject: [Tkinter-discuss] python 3.1 - tkinter 8.4 - no tile?
Message-ID: <AANLkTimc7uCmguGTPRPWM8F+gy+RCJ+4VC25GkX7=3gT@mail.gmail.com>

Hello. I'm beginning to explore Python 3 and tkinter (using Mac OSX 10.6).
Following the directions in (http://wiki.python.org/moin/TkInter) I verified
that
>>> import tkinter
>>> tkinter._test()
does indeed open a little window as expected. So there is SOME fashion of
tkinter and TCL/TK installed on this machine.

Next I attempt to run the "First (Real) Example" in (
http://www.tkdocs.com/tutorial/firstexample.html), but get the error,

    File
"/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/tkinter/ttk.py",
line 47, in _load_tile  master.tk.eval('package require tile')

Looking at the ttk.py file I find it checks tkinter.TkVersion < 8.5, and in
fact tkinter.TkVersion yields 8.4.

Performing the following google search,

     site:mail.python.org 'package require tile'

I observe that this same error has been mentioned 66 times over the last few
years and with several versions of Python and different platforms. (It seems
odd, when this problem has been arising since 2004, the latest version 3.1.2
of Python is still distributed with tkinter 8.4 and yet no tile package. But
I digress.)

The usual advice is to install the tile package from sourceforge. So I tried
to do this but encountered several problems, beginning with, where, ie what
folder? Doesn't really matter, as I find that its ./configure script looks
for a C compiler -- and the Apple Developer package is not installed on this
system. I looked around in /bin and /usr but there doesn't seem to even be a
lowly cc anywhere.

I'd appreciate any suggestions to get past this stone wall.

Thanks,

Dave Cortesi

You're correct that ttk didn't come built-in to Tk until 8.5--hence the 
need for the Tile package with 8.4. I believe the most recent Tile 
package is 0.8 or 0.8.2, at the site you referenced.

As for a compiler, install Apple's developer tools (Xcode and friends) 
and you'll have a working gcc. The dev tools are an optional install on 
the DVD, or can be downloaded from Apple.

Kevin, thanks for taking the time to reply.

I have Xcode installed on one of my macs, but not on the laptop where I
meant to experiment with Py 3 and Tk.

I had hoped, since Tk is the default, expected, distributed-with-python GUI
framework (so says the python wiki) that it would "just work." On the
contrary, it appears that to make it work, I will have to install Xcode, and
figure out how to do an install of this package. And there are several
unknowns in that install, for OS X, beginning with, where in /Library to put
it, or if not in /Library, where? Wherever, I also have to edit my .login to
set PYTHONPATH appropriately so it can be found.

It seems to me this all amounts to quite a steep barrier for someone to
climb, just in order to try out the supposed default GUI.

To me, the really puzzling question is, since this has been the case for
several years (based on the history of the same error being encountered
repeatedly), why is the very latest Python apparently being distributed with
tkinter 8.4 but without tile?

I believe that the system build of Python 2.6 on Snow Leopard (the one 
installed by Apple) is linked against Tk 8.5, which includes the ttk 
widgets. You'd still need to install the Python ttk wrapper module from 
http://code.google.com/p/python-ttk/, but that's easier than building 
the Tile module from scratch. Just download the code, and run "sudo 
/usr/bin/python setup.py install" and you should be in business.

The maintainers of the Mac build of Python from Python.org (not the same 
as the system install of Python included by Apple) decided to keep their 
build of Python linked to 8.4 for backward compatibility--that build of 
Python has to support several versions of OS X. While they do distribute 
Tkinter, they don't include the Tcl/Tk libraries that Tkinter depends 
on--those are installed by Apple. Apple's installation of Tcl/Tk 8.4 
doesn't include Tile for whatever reason, hence, Python's ttk module 
won't work.

Hi i have the following problem with Python Tkinter.
I switch to switch the image background (which i used Tkinter.Label with
image arg to display on the GUI).

How can I do that? the callback function which i have created doesn't seem
to work...
some advice?

below is my code:


import Tkinter as tk
from PIL import Image, ImageTk

root = tk.Tk()

# having problem with switching the image
def callback(event):
    global root
    root.panel1.pack_forget()
    root.panel1.image = image2
    root.panel1.pack()


def app():

    root.title('FIT 2022 Assignment 1')

    # pick an image file you have .bmp .jpg .gif. .png
    # load the file and covert it to a Tkinter image object
    imageFile = "c:\\test1.jpg"
    image1 = ImageTk.PhotoImage(Image.open(imageFile))
    imageFile2 = "c:\\test2.jpg"
    image2 = ImageTk.PhotoImage(Image.open(imageFile2))


    # get the image size
    w = image1.width()
    h = image1.height()


    # position coordinates of root 'upper left corner'
    x = 0
    y = 0


    # make the root window the size of the image
    root.geometry("%dx%d+%d+%d" % (w, h, x, y))


    # root has no image argument, so use a label as a panel
    panel1 = tk.Label(root, image=image1)
    panel1.pack(side='top', fill='both', expand='yes')
    panel1.image = image1
    panel1.bind("<Button-1>", callback)


    panel1.pack()
    root.mainloop()


app()

I wish to do a multi threading program such that user can still use the console to control this GUI.
Can I ask u how can i write a command to force the GUI to switch image instead of relying on the <button-1> event.

thanks to Firat,

his code is as the following: 
import sys
import Tkinter as tk
from PIL import Image, ImageTk

class ImageViewer(object):
    def __init__(self):
        self.imagelist = [image1, image2]
        self.create_widgets()
        self.ind = 0

    def create_widgets(self):
        self.label = tk.Label(image = self.imagelist[0])
        self.label.pack()
        self.label.bind("<Button-1>", self.change_image)

    def change_image(self, event):
        self.ind += 1
        self.label.update()
        try:
            self.label["image"] = self.imagelist[self.ind]
        except IndexError:
            pass


root = tk.Tk()

image1 = ImageTk.PhotoImage(file = "test1.jpg")
image2 = ImageTk.PhotoImage(file = "test2.jpg")


w = image1.width()
h = image1.height()

x = 0
y = 0

root.geometry("%dx%d+%d+%d" % (w, h, x, y))
app = ImageViewer()

root.mainloop()

Hello;

Is it possible to have a set of buttons, all calling to the same function, recognize which of the buttons was the one that call the function? 

'Cause what I want to do, is create a set of buttons, where I will not know how many buttons will be created, that will depend on the input of the user. Once the user have this, he will click one of those buttons, and depending on which button was press, the program will erase that part of the input that the operator gave.

Hi Guido,

 One solution to your problem, using lambda to define the function call.

from Tkinter import *

def killBut(but):
    but.pack_forget()

tk = Tk()

but1=Button(tk, text="B1")
but1['command']=lambda b=but1: killBut(b)
but1.pack(side=LEFT)

but2=Button(tk, text="B2")
but2['command']=lambda b=but2: killBut(b)
but2.pack(side=LEFT)

tk.mainloop()

I am not sure what you want to achieve; in case you want the user to be
able to use the keyboard insted of the mouse, you can simply use
bindings to Key events instead of <Button-1>, like <Control-n> for a
"next image"-callback and <Control-p> for "previous image". You can even
apply such bindings to the toplevel window as a whole, so the users
will not have to set the keyboard focus to a particular widget.

If you want to control the window from a different application, you can
try to add a signal handler using Python's signal module (however,
this may not be supported on all platforms).

Or do you want the application to automagically switch the image after
a given amount of time? Then you can use a simple after() loop, like:

    def switch_image():
        ImageViewer.change_image()
        root.after(5000, switch_image)
    root.after(5000, switch_image)

In this example the change_image() method of course needs to take care
that after displaying the last image from the images list it will start
over again with the first one.

I hope this helps

And, in yet another direction, I wonder if the original questioner is
confused about the relation between "multi threading" and GUI 
responsiveness (and concurrency, and so on).  It's possible <URL:

Subject: [Tkinter-discuss]  Entry Widget that can't enter into at first.
Message-ID: <29449209.post@talk.nabble.com>


What basically happens is if I use the application all features work fine
except the entry widget I have created. I cannot add text or even get the
cursor to appear in the entry field.

 What is odd is I have a askyesno button for quiting. If I hit "no" and
return to the application, I can then enter text and move the cursor with
the tab to other features and buttons in my gui.

How do I get the entry box to work?  

The problem might be tied to windows, frames and parents (which I still
don't fully understand even though I have built 5 gui's now).  The relevant
code is abridged as below:

if __name__ == '__main__':
    root = Tk()
    root.title('Artifact Pointer')# adapted from_PyView 1.0')
    Label(root, text="Point to Artifacts Observed").pack()
    SlideShow(root, picdir=picdir, artdir=artdir, bd=3, relief=SUNKEN)
    root.mainloop()

preceeded by:

class SlideShow(Frame):
    def __init__(self, parent=root, picdir='.', artdir='.', msecs=3000,
**args):#msecs is legacy
        Frame.__init__(self, parent, args)
        self.parent = root
        self.makeWidgets()

and under def makeWidgets I have:

self.vent=StringVar()
Entry(self,textvariable=self.vent).pack()


I have tried some variants and have read several forums and Lutz and still
am not getting this sorted out.  It is odd to me that it works, but only
AFTER, I hit no under askyesno button.

I have some elements on the screen (Labels, most importantly) which content
has to be updated every iteration of the algorithm run, e.g. "Iteration ="
[i] for i in range(n). I've tried using mainframe.update_idletasks()
and Label(mainframe.update_ideltasks(),textvariable=var).grid(column=1,row=1),
but without success so far. In MATLAB this command is drawnow.

I believe I understand your description.

For a "quick fix", I recommend you experiment with update() (as 
opposed to update_idletasks()) applied to mainframe.

For better long-term maintainability, though, you almost 
certainly should "return to the event loop" on each iteration
of your run (there are also multi-threading approaches, but 
they're somewhat trickier to code correctly).

thanks, in one of these articles it says. 'Be careful - Tkinter in not
re-entrant'. MAybe this is the problem? So far I've tried

(1) Label(mainframe.update_idletasks(),textvariable=best,bg='#321000',fg='#000fff000',font=("Helvetica",x1)).grid(column=1,row=1)

and

(2)
mainframe = Frame(root)
mainframe.grid(column=1000, row=1000, sticky=(N, W, E, S))
mainframe.columnconfigure(0, weight=1)
mainframe.rowconfigure(0, weight=1)
mainframe.update()

Neither worked, of course, otherwise I woudln't be posting it)

I'm not using any classes

If I am not mistaken you want something like this:

1) http://paste-it.net/public/i2de44d/ (with threads and classes)

2) http://paste-it.net/public/f5e340e/ (without threads and classes)

Note that without threads, we need to use the update() method. However,
without threads you will experience some degree of "blockage" in the
application anyway.

Hi,

  Its always better if you provide code which can be run. Reduce
out all irrelevant code. (often this process shows you the problem
in your code).

If you have an askyesno dialogue open, that hogs the keyboard,
so you cannot type to another window while it is open.

update() is *not* essential:  after() provides a non-threading alternative.

I entirely agree with your main point, though, that you have two codings
which supply the desired functionality.

I agree. If you would not like to use update(), you can use after() in your
code with pretty much the same functionality:

thanks guys, this does seem to work...nevertheless, since I'm quite new to
both python and gui design, one more question: how would I do the same, but
launching the counter at the click of the button? I tried (from Firat's last
example)

def increment(*args):    var.set(var.get()+1)    root.after(1000, increment)


but1=Button(text="click me", command=increment)
but1.grid()

Ok, it actually seems to work, apart from one thing: what if I need to
update an array, rather than a single element? I mean, each iteration I
store an array, then use it the next iteration (naturally, the first array
is generated randomly). This worked for the counter:


   1. def run(*args):
   2.     n=0;master=mainframe
   3.     best.set('test # %d' % (n))
   4.     n += 1
   5.     if n <= 10:
   6.         mainframe.after(1000, run, n, master)




but when I do the same for a matrix, I get the computer either hung or some
errors. Ususally, I run a loop for G generations within the function, but in
this example the
algorithm itself restarts G times. Any ideas how to handle this?

Sorry for being messy, it's just the ONLY thing that I can't make work here,
everything is is just fine)

thanks

I am not sure whether my understanding of your problem is correct, but if I
am not wrong you want something like this:

thnx a lot, Firat, I sorted it out a few minutes b4 reading yr post)

i just needed 2 loops: one for the counter (while j<G) and then within this
loop to check if j is still <G to set the values for the Labels and simply
mainframe.update(). Somehow it didn't work earlier, probably something was
wrong with my identation or something. So thanx a lot!

Subject: [Tkinter-discuss]  Multiple windows,
 accessing variables across them won't work for me (Using Tkinter)
Message-ID: <29503063.post@talk.nabble.com>


Hi!
I've been working on this app last days, and can't get passed this problem:
I've created two windows, (one is created by a button click in the first
window), and from the other window I want to change some variables defined
in the first window.

I'm guessing either I haven't understood the whole parent thingy, or messed
up somewhere there.

The source code is:
(there's some translations and explanations below)


#!/usr/bin/python
# -*- coding: utf-8 -*-

from __future__ import division
import Tkinter


class enhetsomvandlare_tk(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()


    def initialize(self):
        self.grid()

        self.LV = Tkinter.StringVar()
        label = Tkinter.Label(self,textvariable=self.LV,
                              anchor="w",fg="white",bg="blue")
        label.grid(column=0,row=0,columnspan=1,sticky='EW')
        self.LV.set(u"Lbs to Kg")

	global enhet
	enhet = "lbstokg"


        self.entryVariable1 = Tkinter.StringVar()
        self.entry = Tkinter.Entry(self,textvariable=self.entryVariable1)
        self.entry.grid(column=0,row=1,sticky='W')
        self.entry.bind("<Return>", self.OnPressEnter)
        self.entryVariable1.set(u"")

        self.entryVariable2 = Tkinter.StringVar()
        self.entry = Tkinter.Entry(self,textvariable=self.entryVariable2)
        self.entry.grid(column=1,row=1,sticky='W')
        self.entry.bind("<Return>", self.OnPressEnter)
        self.entryVariable2.set(u"")



        raknaknapp = Tkinter.Button(self,text=u"R?kna ut!",
                                command=self.Onraknaknapp1)
        raknaknapp.grid(column=2,row=1)

        Change_units = Tkinter.Button(self,text=u"Change Units",
                                command=self.OnChange_units)
        Change_units.grid(column=1,row=2)


        self.grid_columnconfigure(0,weight=1)
        self.grid_columnconfigure(1,weight=1)
        self.grid_columnconfigure(2,weight=1)
        self.resizable(True,False)
        self.update()
        self.geometry(self.geometry())




    def Onraknaknapp1(self):
	if enhet == "lbstokg":
		lbs = float(self.entryVariable1.get())
		kg = lbs / 0.455
		self.entryVariable2.set(kg)

	elif enhet == "kgtolbs":
		kg = float(self.entryVariable1.get())
		lbs = kg * 0.455
		self.entryVariable2.set(lbs)



    def OnChange_units(self):

	class Change_units_tk(Tkinter.Tk):
	    def __init__(self,parent):
	        Tkinter.Tk.__init__(self,parent)
	        self.parent = parent
	        self.initialize()

	    def initialize(self):
	        self.grid()

	        self.LV2 = Tkinter.StringVar()
	        label = Tkinter.Label(self,textvariable=self.LV2,
	        	                      anchor="w",fg="white",bg="blue")
	        label.grid(column=0,row=0,columnspan=2,sticky='EW')
	        self.LV2.set(u"Choose Unit...")

		kgtolbs = Tkinter.Button(self,text=u"Kg to lbs",
                                command=self.Onkgtolbs)
        	kgtolbs.grid(column=0,row=1)

		lbstokg = Tkinter.Button(self,text=u"Lbs to kg",
                                command=self.Onlbstokg)
        	lbstokg.grid(column=1,row=1)

	        self.grid_columnconfigure(0,weight=1)
	        self.grid_columnconfigure(1,weight=1)
	        self.grid_columnconfigure(2,weight=1)
	        self.resizable(True,False)
	        self.update()
	        self.geometry(self.geometry())

	    def Onkgtolbs(self):
		self.LV.set("Kg to lbs")
		global enhet
		enhet = "kgtolbs"

	    def Onlbstokg(self):
		self.LV.set("Lbs to kg")
		global enhet
		enhet = "lbstokg"


	if __name__ == "__main__":
	    app = Change_units_tk(enhetsomvandlare_tk)
	    app.title("What unit?")


    def OnPressEnter(self,event):
        self.LV.set( "Hej" )



if __name__ == "__main__":
    app = enhetsomvandlare_tk(None)
    app.title("Robert's Enhetsomvandlare")
    app.mainloop()



(Some things are swedish, so I'll translate them to make this easier to
understand)
Legend for my code:

enhet = unit
LV = Labelvariable
raknaknapp = calculatebutton
R?kna ut = calculate






Now as soon as I get the crossover thing to work I'll start adding more
math, functions and other things to it to make it useful. But right now I
want to get rid of this error message:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1413, in __call__
    return self.func(*args)
  File "/home/robert/Desktop/programmering/python/12 enhets
omvandlare/12.py", line 118, in OnChange_units
    app = Change_units_tk(enhetsomvandlare_tk)
  File "/home/robert/Desktop/programmering/python/12 enhets
omvandlare/12.py", line 78, in __init__
    Tkinter.Tk.__init__(self,parent)
  File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1646, in __init__
    self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
TypeError: create() argument 1 must be string or None, not classobj

OR

when i have the line:
 app = Change_units_tk(enhetsomvandlare_tk)
changed to:
 app = Change_units_tk(None)
I will get the error message:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1413, in __call__
    return self.func(*args)
  File "/home/robert/Desktop/programmering/python/12 enhets

    self.LV.set("Kg to lbs")
  File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1725, in __getattr__
    return getattr(self.tk, attr)
AttributeError: LV

Which is the one I really don't get...



Anyways, I've searched the net for some help, but couldn't find anything
really helpful. (I know I probably missed it, but this was easier... :P)

Help is appreciated, (I'm a first time poster).

Have a nice day! :)

Hello,

In Tkinter, when you want to create a secondary window you do not have to
implement a whole new class. What you need to do is just create a new
toplevel. Furthermore, never use "globals" within a class.

I made some modifications to your code. You can find the modified version of
your code in here:

Subject: [Tkinter-discuss] Canvas.postscript() fails to render some fonts
	properly
Message-ID: <20100823222319.76ee2caa.klappnase@web.de>

Hello all,

I am stuck here with a strange  problem creating postscript from a
Tkinter Canvas (the OS is debian linux).
I found that Canvas.postscript() fails to render some fonts correctly and
uses something like helvetica or courier (I guess) instead. From what the
canvas man page says, I thought I should try to add a fontmap to the
postscript() command, but I cannot seem to get it working, and I am not
sure if it is because of improper use of the fontmap option or if
something else is wrong. 
>From the few Tcl resources I could find I tried to set up a minimal tcl
example, trying to find out how the "fontmap" works, because I could not
find any useful Python resources:

canvas .c -width 300 -height 300 -bg white
pack .c
set fonty [font create -family "comic sans ms" -size 16]
.c create text 20 20 -font $fonty -text "ich wollt ich waer ein huhn" -anchor nw
set fontMap($fonty) [list "comic sans ms" 16]
update idletasks
.c postscript -file "~/test.ps" -fontmap fontMap

However this produces an obviously broken postscript file that cannot be opened.
If I omit the -fontmap option, the file can be opened, but I get a font like
helvetica or so.

Does anyone have a clue on this?

Regards

Michael

Hello,

Unfortunately there are not enough documentation about Python-tk postscript
manipulation. Information is scattered here and there.

A sample code could be like this:

In addition to my previous e-mail, I want to add the following link in which
there are some explanations and an example code for creating postscript.
However the following is only useful if you are into Tcl/Tk:

Hi,

  Its always better if you provide code which can be run. Reduce
out all irrelevant code. (often this process shows you the problem
in your code).

If you have an askyesno dialogue open, that hogs the keyboard,
so you cannot type to another window while it is open.

Mick


>>> >>>>>>>>>>>>>>
>>>>>I have attached a stripped down version of the code.  [I do realize
that the askyesno takes priority.]

The code is intended to bring in an image and place it on a canvas, and
allow the user to mark locations on the image with their mouse.  You will
need a small jpg or other to run the code when requested by askfilename. 
The entry field is to allow for extraneous comment.  I am having trouble
with this entry field. 

I cannot 
1) enter content into the entry field without first trying to quit and then
cancelling - I cannot expect the user to do this because it is not
intuitive.  I should be able to enter the entry field immediately if I want
to.
2) I cannot seem to get the radio button to default to something I want..
instead it has all buttons marked when the gui comes up.

I cannot reproduce this here, as soon as the file dialog is closed I can
click into the entry and type something in.

You need to define a value for the radiobutton's variable, otherwise all
buttons will be "off" when instantiated, so simply add something like

    self.var.set('key1')

to makeWidgets() .

I hope this helps

Actually, I can reproduce the error described by the original poster... I am
not exactly sure about the true dynamics of the solution, but after_idle()
method seems to solve the problem in a way. Perhaps, for one reason or the
other, the program cannot return to the main window properly even though the
open dialog is terminated.

Therefore:
[code]
    def __init__(self, parent=None, picdir='.', artdir='.', **args):
        Frame.__init__(self, parent, args)
        self.parent = parent
        self.makeWidgets()
        self.pack(expand=YES, fill=BOTH)
        self.makeBindings()
        self.opens = picdir
        self.artpics = artdir
        self.drawn  = None

        #note the use of after_idle()
        self.begin = self.after_idle(self.onOpen)

        self.pick = 'TBD'
        return
[/code]

this example does basically the same as my tcl snippet; it works ok with
verdana, but for some reason fails on comic sans ms and some other fonts,
but I cannot see why some fonts work and some don't. For example, also
"bitstream vera sans mono" fails wheras "andale mono" works. Maybe I
should mention that all these fonts are displayed correctly in the
canvas. For the "working" fonts I do not even need to pass a fontmap to
postscript().

I have already seen these, however they don't help me much, because of
the strange problems described above. So I am still not sure if it's
improper use of the fontmap or some other weird problem with either Tk or
maybe my system's postscript engine.

Hello,

It seems to me that for the most part, you are having issues with font names
that have spaces between the words making up the font name. For example:
"DejaVu Sans Condensed"

If there are spaces between words, you should define self.font as a tuple:

self.font = ("DejaVu Sans Condensed",)

Note the trailing comma in accordance with the rules of creating a
one-element tuple...

Although it is not mandatory, you would better use the exact same cases
(uppercase vs lowercase) for the fonts as seen from the output of:

[code]
root = Tk()
root.tk.call("font", "families")
[/code]

Please try this way, and tell me if it solves the problem.

Hello,

I found some useful stuff at:
http://www.tcl.tk/man/tcl8.4/TkCmd/canvas.htm(Find "-fontmap" there)

The above document recommends a notation like: *
-*-Courier-Bold-R-Normal--*-120-

*I think this notation will be like this for those fonts that have spaces:

*"-*-DejaVu Serif Condensed-Bold-R-Normal--*-120-*"

I know that, otherwise Tk will complain "expected an integer but got
'sans'" or so :)

I thought it might have something to do with the spaces first, too, but
as I mentioned "andale mono" or "penguin attack" work, wheras "clean" or
"avantgarde" don't.

I already used the font names this way, here I get all lower case variants
of all font names (like "dejavu sans") from tkFont.families().
I am really baffled with this (o.O)

I tried some more with the fontmap, I changed the font in your example
into:

    self.font = tkFont.Font(family="courier", weight='normal', size=43)

and changed the first lines of create_ps() into:

    root.tk.call("set", "fontMap(%s)" % self.font, ('verdana-bold', 43))
    self.ps = self.canvas.postscript(fontmap='fontMap')

however if I change "verdana-bold" into "verdana" or "verdana-normal" it does
*not* work and the postscript uses "courier" (as seen on the screen).
I was not able yet to add a font name containing white space to the fontmap though :(

Regards

Michael

Gentlemen, I recommend you mention what operating system (or perhaps,
more to the point, what windowing system) is giving you these results.
Errors or inconsistencies in Tkinter are particularly likely to arise
in platform-specific code having to do with window managers.

Hello,

It looks like that postscript() function cannot render every font with no
obvious reason. "Renderable" fonts are rendered correctly regardless of
whether they contain spaces or not... However it seems that, alternatively,
we can achieve what we want through the Image, ImageDraw and ImageFont
modules. All we need to know is the name of the .ttf file to which the font
name corresponds.

Here is the code: http://paste-it.net/public/t66c5c0/

Please note that I wrote this code on an XP machine. Considering that you
are on Debian, this little how to might be of help to you for configuring
TrueType fonts:

I tested the original poster's code on Ubuntu Karmic Koala (GNOME). As soon
as the file dialog is closed, the entry widget is ready for typing. So it
seems that this problem is specific to Windows OS.

By the way, I created a new record for this issue with Cameron Laird's

I guess you are right, and using the fontmap option does not seem to make
any difference; when I use e.g. times in the canvas and override it
through the fontmap with verdana, I get verdana in the postscript. If I
use e.g. "clean" instead of verdana I get something that looks like
courier. So it looks like the good news is that I don't need to bother
trying to get the fontmap working when the font name contains white
space :)

Nice, i did not know that this is possible, but unfortunately this is no
option for me. I want that my app can be run on any linux machine, so I
would have to ship my own fonts to know where exactly the files are.

I wonder if there is some way to determine from within Tkinter which
fonts can't be used with postscript; if yes I could simply remove these
from the menu where the font can be selected, I could live very well with
that. What's bad is that the font that is printed is not the one the user
sees on the screen.

Regards

Michael

In Tk documentation, it reads:

"(...) Tk attempts to guess what Postscript font to use. Tk's guesses
generally only work for well-known fonts such as Times and Helvetica and
Courier (...)"

source: http://www.tcl.tk/man/tcl8.4/TkCmd/canvas.htm (see "-fontmap"
section)

So if you would like to be on the safe side, you are only limited to Times,
Helvetica and Courier...

In GNU/Linux, as you know, fonts are generally in /usr/share/fonts.
Therefore you can take this path as the base for your application's font
folder.

Also I believe that distributing your own fonts is not a bad idea. If I were
you, I would just collect all the fonts I need into a folder, and distribute
that folder with my application. This way, I would always know where and
what the fonts are... For instance, suppose that you collected all your .tff
files in a folder named "freefont", and you know that there is a .tff file
named "FreeSansOblique.ttf" in that folder:

http://paste-it.net/public/ke2fa61/

There are some interesting websites giving away free fonts over the net. For
example:

http://www.webpagepublicity.com/free-fonts.html

I tested some of these fonts in my code (under Ubuntu), and they all work.

Good Luck!
Firat

I have seen this in the description of the fontmap option, but it seems a
little outdated to me, as there is no difference between using fontmap or
not and even obscure fonts as "penguin attack" are found, no matter if
they are written upper or lower case. I also got the
same impression from a comp.lang.tcl search for "fontmap", where tha vast
majority of matches was older than 6 or 7 years; it looks like Tk's
guessing capabilities have improved :)

 Not necessarily, for example might people install third-party fonts
into /usr/local or /opt or into their /home directory.

The downside is, that people then cannot use their system-wide installed
fonts which they might prefer...

Anyway, I think I will just keep it like it is for now.
If I weren't such a "comic sans ms" aficinado maybe I had never noticed
this and no one complained so far, so I guess people can live with it,
too. It just would have been nice to have a bug free UI.

Thanks again

I am the original poster.? I can confirm that I am using a Windows XP operating 
system.? I do not have ready access to another OS (right now).

I tested the original poster's code on Ubuntu Karmic Koala (GNOME). As soon as 
the file dialog is closed, the entry widget is ready for typing. So it seems 
that this problem is specific to Windows OS.

Hello Kevin,

I downloaded the python ttk wrapper and ran the command as you 
suggested... but I'm not having any luck importing ttk (Mac OS X 10.6.4, 
running the supplied python 2.6.5).

Any suggestions?

TIA,

Hello all,

I did now some further investigation on this topic and I thought I
might share what I found here, for the archives :)

It seems that in fact the problem is the name of the postscript font
created by Tk. Tk itself treats all font names case insensitive, so
"cOMiC SanS mS" is equivalent with "comic sans ms". Postscript however
appears to be quite fastidious about the spelling of a font name. Even
worse, it looks like the requested spelling of a font can differ from one
postscript interpreter to another.
Tk itself creates postscript font names always the same way: the first
letter capitalized, the rest lower case, as in "Courier". If the name
contains white space, each "word" is capitalized and the white space
removed, so e.g. "comic sans ms" becomes "ComicSansMs". This behavior is
hard coded in tkFont.c . In my example the postscript interpreter insists
on "ComicSansMS" though and therefore fails to print the font correctly.
This is where the fontmap option comes in, passing the exact postscript
font name to the fontmap like:

   set fontMap($fonty) {"ComicSansMS" 16}
   .c postscript -file "~/test.ps" -fontmap fontMap

the "comic" font works as expected.
However the bad thing is that this does not mean that it will work on any
system, e.g. the same postscript file that works on my debian linux system
did *not* work on my windows2000 box with a newly installed ghostscript
(latest version).
However if it is for personal use only, it seems to be better to directly
add entries to the postscript fontmap (on unix systems usually
/usr/share/ghostscript/<version>/lib/Fontmap )
In my example this entry simply looks like:

/ComicSansMs			/ComicSansMS	;

or, probably better, add custom entries like this to a file MyFontmap in
the same folder and add a line

(MyFontmap) .runlibfile

to Fontmap, so the private entries won't be lost after an update.

Monte, do you have python 3.1 or 2.6.5. I had a mac as well, and when I try to use ttk didn't work. They way I solve was to copy the ttk.py file inside of the site-packages, which in my case is inside of:

Library/Frameworks/Python.framewors/Versions/2.7/lib/python2.7/site-packages

Than, what I will recommend is to install from the source, not the installer disk image. If you install from the installer disk image, once you try to use ttk, you will see that the Tk and Tcl connected to ttk are version 8.4, which will not work.

If you need details instructions on how to install from the source let me know.

I hope this helps. Regards!

Guido Carballo

Hello Guido,

I recently (yesterday) went through and cleaned out the 'other' stuff 
I'd accumulated over a period of tinkering; currently I have the default 
Python that ships with 10.6.x, and then a 'fresh' install of MacPython 
2.6.5 from python.org via the disk image file I downloaded from there. 
I'd debated about whether to use MacPython or Activestate Python, which 
sounded like it supported the newer versions of tk better, but it also 
sounded like in order for that to work I'd have to download and install 
Activestate Tcl as well... maybe that's the simplest option...?

Are you saying that in order to use ttk with MacPython I need to compile 
python from the source code?

Is there some particular reason why the folks @ python seem to resist 
upgrading to tkinter 8.5 & tile/ttk?  I thought it had been out for 
*years* now (well before python 2.6, anyways)... why do I need to jump 
thru all these dang hoops to use what seems like it should be the 
current version of things?  Sorry for the vent... I realize I'm very new 
to this and probably lack perspective and all that, but I'd really like 
to know.

Thanks,

Monte

Monte;

I don't know that. Maybe somebody from here might be able to answer that, but I don't know. I'm kinda new into Tkinter as well. I have less than a year using it.

What I told you was what worked for me. And yes, what worked for me was installing source, which I download from here:

http://www.python.org/download/

I don't understand as well, why the Mac Os x Installer Disk Image don't come already with Tk/Tcl 8.5, specially since the Windows installer already comes with all that ready, but well. I would even suggest that Python should come with ttk.

Those anybody knows what Python doesn't comes already with ttk? Why the Mac installer doesn't have Tk/Tcl as part of the installation?

But anyway Monte, in the mean time, try what I suggest. For me works just fine. As I told you before, if you need detail instructions on how to install Python and ttk from source, let me know.

Regards!

Guido Carballo

ttk is standard, I believe, in 3.1, and perhaps 2.7? (Someone correct me 
here.)

The Mac installer doesn't include Tcl/Tk because the Mac already ships 
Tcl/Tk, both 8.5 and 8.4 on Snow Leopard.
