No, it doesn't :-(

I used the following test code:

<code>
#! /usr/bin/python

from time import sleep
import sys,os,thread
from Tkinter import *

def one_th():
  sys.stderr.write('In the thread...\n')

if os.fork()==0:
  os.setsid()
  if os.fork()==0:
    sys.stdin=open('/dev/null','r')
    sys.stdout=open('/dev/null','w')

    thread.start_new_thread(one_th,())
    while True:
      sleep(60)
      try:
        rtk=Tk(screenName=':0.0')
      except:
        continue
      break
    Label(rtk,text='It works').grid()
    sys.stderr.write('Entering mainloop\n')
    rtk.mainloop()

  sys.exit(0)
</code>

I can see on root's console "In the thread...", and, after a while, "Entering mainloop", but
nothing shows up in user's screen.

Maybe it's simply impossible...

Does anyone know about a Tkinter extension to allow 90dgr rotated labels (or other text widget)?

Thanks,

Subject: [Tkinter-discuss] Ann.: Updated TkTreectrl wrapper
Message-ID: <20061204185229.77ccc6f7.klappnase@web.de>

Hi,

I have  uploaded an updated version of the Tkinter wrapper for the Tk
treectrl widget (http://tktreectrl.sourceforge.net).
The major change in this release is the introduction of a few new
widget classes:
_MultiListbox_ is a Treectrl widget set up to work as a (more or less)
full-featured and very flexible multi column listbox widget.
The _ScrolledTreectrl_ and _ScrolledMultiListbox_ classes use ideas
shamelessly stolen from Pmw.ScrolledListbox to add one or two static or
automatic scrollbars to the widgets. They both inherit from the
_ScrolledWidget_ class that is supposed to make it easy to add
scrollbars to any other Listbox or Canvas alike Tkinter widget.

Changes to the Treectrl widget:
I added the second (optional) _last_ argument to column_delete() (new
in treectrl-2.1.1) and fixed a few minor bugs.

The url is: <http://klappnase.zexxo.net/TkinterTreectrl/index.html>

Regards

Michael

here is an example of rotated text using BLT:

<code>
#! /usr/bin/python

from Tkinter import *

r=Tk()
g=Pmw.Blt.Graph(r)
g.axis_configure('x',hide=1)
g.axis_configure('y',hide=1)

g.marker_create('text',text='Finch Ave.',coord=(.3,.17),background='#ffffff')
g.marker_create('text',text='Martin Ross St.',coord=(.3,.72),background='#ffffff')
g.marker_create('line',coord=(.1,.7,.48,.7,.48,.2,.2,.2))
g.marker_create('line',coord=(.1,.75,.48,.75,.48,.92))

I was trying to disable Radiobutton widget, with passing

Tkinter.Radiobutton(...,state=Tkinter.DISABLED) and Tkinter.Radiobutton(...,state=DISABLED) and  but no success. In first two cases there is no error message but radiobutton doesn't get disabled...
In the third case I got Python error saying DISABLED is not defined.

Is there any known issue/problem with disabling Radiobutton widget?

======

It sounds like you may not be importing Tkinter in the "usual" way.

from Tkinter import *

is what I usually use and then things like  state=DISABLED  will work.

from Tkinter import *
Root = Tk()
RadButVar = StringVar()
RadButVar.set("2") <- set to which button should be initially "on" if any
Rb1 = Radiobutton(Root, text = "TestBut1", variable = RadButVar, value = 
"1")
Rb1.pack()
Rb2 = Radiobutton(Root, text = "TestBut2", variable = RadButVar, value = 
"2")
Rb2.pack()
Root.mainloop()

The above works and I can put  state=DISABLED  in either or both of the 
Radiobutton lines and get predictable results.

I can also do things like  Rb2.config(state = DISABLED)  later in the 
program and it works, however, if a radiobutton is selected when you change 
the state to DISABLED it will stay selected until the user selects another 
one of the associated radiobuttons.

Message-ID: <45784B45.6030809@codebykevin.com>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'm trying to use pybwidgets in an application I'm developing; the
BWidgets listbox supports insertion of images alongside text, and is
nicer than the alternatives I've looked at (various tree widgets, for
instance).

I've found what I think is a bug. When the BWidgets listbox is placed
inside a panewindow, it does not properly display the
selectforeground/selectbackground colors--in fact, it provides no visual
feedback at all that a listbox item is selected.

The following code illustrates the problem. The listbox does respond to
button events; when an item is selected, text is printed to the text
widget. But there is no visual selection feedback in the listbox itself.
Can someone review this, test it, and let me know if I'm doing something
wrong, or if this is in fact a bug? Thanks.

thing), you can generally rest assured that you'll be almost always fine 
when you do a full namespace import of Tkinter module.

Harlin Seritt

=======

Yeah, I forgot to mention that using something like  from Tkinter import * 
can get you into trouble if you happen to do something like name a variable 
"Radiobutton".  To see a list of things you shouldn't name variables and 
functions you can start the Python interpreter, enter  'from Tkinter import 
*'  and then  dir()  and it will list everything...although you also have to 
then enter commands like  dir(__builtins__), etc.  to get the complete list.

Is there a way to get the complete list of used keywords with one command?

In my programs my variables always start with an upper case letter and my 
functions always start with a lower case letter (that's just backwards to 
normal human beings) which has seemed to keep me out of trouble for about 
300,000 lines of code.  I usually do things like

from time import sleep, gmtime, time

instead of using  from time import *.  I guess it's only Tkinter where I 
import *.

I've always disliked the "from xxx import *" paradigm, specifically because
it makes it harder to recognize where certain symbols come from. As the Zen
of Python teaches us, "Namespaces are one honking great idea!"

As an alternative I use "import Tkinter as T". This doesn't increase the
typing burden much --- Button(...) becomes T.Button(...) --- but it always
allows me to recognize any symbols belonging to Tkinter's namespace.

Just my two cents.

Re: [Tkinter-discuss] Tkinter-discuss Digest, Vol 34, Issue 5I have a "form" in my program that has a Text() field with a little text, some Buttons with pictures, and some Labels inserted into it.  If I just do a Text().get(0.0, END) all I get is the text.  Is there a way to get, pardon my C, a pointer to the Labels so I can cget the text from them?

A picture of my form: www.greschke.com/unlinked/images/getem.jpg

I specifically want the 7-digit number in the light blue areas (the Labels).  I can keep a list of the numbers as I insert the Labels, but the user may edit some of them out of the list (like with the keyboard), so then my list wouldn't match.

Thanks!

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'm trying to get an alphabetical list of the available fonts on my
system for use in a Tkinter application.

This code returns an unsorted tuple of the fonts:

fonts = tkFont.families()

To get a sorted list, I've assembled the following snippet, based on
code in idlelib:


fonts=list(tkFont.families())
fontlist=fonts.sort()
print fontlist

However, this code doesn't work. "print fontlist" returns the output
"None" in my console, and no list of fonts is displayed in my application.

Any ideas on what I'm doing wrong?

Yer gonna kick yourself. :)

fonts = list(tkFont.families())
fonts.sort()
print fonts

.sort() just sorts in place.  It doesn't return anything.

Subject: [Tkinter-discuss] tkFileDialog: shuts down root window
Message-ID: <8000939.post@talk.nabble.com>


Hello,

I'm using python tkinter to create a GUI.  I wish to collect 4 files from a
user so for this part I created a GUI that has a Label, Entry  and Button. 
To get the file I use tkFileDialog askopenfilename.  My problem is that
after a few file selections using the tkFileDialog, the root window is
destroyed (the whole program just dissappears). 

I have created a simpler example and was able to reproduce the same thing
with this.  I've just started using tkinter so I have no idea what I may be
doing wrong.  If anyone has any ideas please let me know.

If you run the following code, just click the Browse button, and select a
file.  The file selected is displayed in the Entry field.  Click the Browse
button again and select another file or the same file.  Do those steps
several times and for me after the sixth or seventh time the window shuts
down.  If I restart the program, it may only take one or two times for the
root window to be destroyed.

BTW, I'm using python 2.4 on Windows XP.  Does anyone have any ideas why
this may be happening?

I don't have Pmw on this machine, but if I comment out the "import Pmw" 
line, the program works perfectly fine for me (Python 2.4.3, XP, running 
from the command prompt).

- do you still get the same problem if you remove the Pmw import ?

- how do you run the program ?

Hello, Thank you for the reply.

I commented out the Pmw import and still have the same results.

I usually run the program through  Eclipse with the Pydev plugin.  But I
also have tried running it by bringing up a window console and I have the
same result.  So I don't think it is a problem is with the IDE.

This morning I ran the program on a different computer and still was able to
reproduce on a different computer.  One thing to note is that this morning
the computer is a P4 2.8 Ghz machine.  It took much longer to destroy the
root window.  (The first time I would say 20 times, but after the first
time, it only took 4 or 5 times to do it a second time)  The other computer
is a P4 1.8 Ghz, it takes fewer times.  Could it be a race condition?

Thank you again for your response.

In this context:

from Tkinter import *

Root = Tk()

def about():
    # Whatever
    return

def progQuitter():
    # Whatever
    return

def makeMenu(Win):
    global Fi   # or most likely a dictionary that achieves the same thing
    global Hp
    global Top
    Top = Menu(Win)
    Win.configure(menu = Top)
    Fi = Menu(Top, tearoff = 0)
    Top.add_cascade(label = "File", menu = Fi)
    Fi.add_command(label = "Quit", command = progQuitter)
    Hp = Menu(Top, tearoff = 0)
    Top.add_cascade(label = "Help", menu = Hp)
    Hp.add_command(label = "About", command = about)
    return

makeMenu(Root)
Root.mainloop()

I want to write a function like

    def disableMenu("File", "Quit")
        # Finds the Quit item in File cascade and sets its state to DISABLED
        return

How would disableMenu() entrycget() through the menu items to find the index 
of the "Quit" item?  How do I get a list of the cascades ("File", "Help" - 
just looping through Top.entrycget(i, "label") seems to do that) and then a 
list of the items in those cascades ("Quit", "About")?

As an aside

    print Fi.entrycget(1, "label")

seems to work, but (2, "label") doesn't.  It says "-label" is an unknown 
option.  I guess I don't know what I'm doing. :)

Thanks!

Bob

I should have said that entrycget(2, "label") doesn't work on a longer menu
(in my real program) not this example snippit.

Ahha!  I know how to reproduce this!  I was starting to think it was the
Eclipse IDE but I did a reboot and ran from the windows console to make sure
it wasn't

to repeat:
1) Right after reboot, I opened a window console, did a cd to my python
directory and entered "python <mytestcodemodulename>.py" to open the ui
window
2) click the browse button 
- file browser opens with my list of .csv files
4) here is the trick - DOUBLE click the file you want in the list.  
- with the double click you don't need to click the Open button, the double
clicked file is entered in Entry field and tkfiledialog window closes
5) click the Browse button in the UI again and here is where I get some
different behaviors.  Some times after clicking the browse button the second
time, I can wait, (for me it took about 15 seconds), and then the root
window is destroyed.  Other times, the root window is destroyed immediately,
other times I need to do the browse, double click, browse, double click
three or four times.  But seems that I can consistently repeat this with at
max four of these browse, double click cycles.    


It seems that all I have to do is have one double click in the tkfiledialog
to kill my whole app.  Can anyone else reproduce this? 

Thanks again.

This is an ignorant question, so thanks in advance for your patience.

I'm trying to code a card game, and I have lots of little .gif's used to 
display card images as follows:

from Tkinter import *
import Image, ImageTk
...
class Card(object):

  def display(self, canvas, x, y, angle)
     im = Image.open(self.URL)
     im = im.rotate(angle)
    self.image = ImageTk.PhotoImage(im)
    canvas.create_image(x,y,image=self.image)

...

The idea is to show four hands of 13 cards, each hand facing inwards.

Oddly, when I display them, the right hand gets truncated.  The 
dimensions of the canvas print out as 265x378.  I can fix it by 
assigning height and width of the canvas manually, but it made me 
wonder: why doesn't the canvas autosize?

Thanks,
Jeff Cagle

Probably because it is not wanted in many cases that the size of the widget
increases when new items are added. Imagine a situation, where the bounding
box of all canvas item exceeds the screen dimensions. Or maybe you do not
want to resize the widget at all but use scrollbars instead.

For your problem it might be the best choice to check out the maximum
possible size of the canvas and apply this manually.

I hope this helps

Michael

I believe I have the missing piece to this puzzle.  This only happens when
selecting files from the Desktop.  If I'm selecting files from any other
location it is fine.

To repeat:
1) in the code that I submitted, change the initialdir to your python dir:
e.g. 'C:\\Python24'
2) run code  -  window appears
3) click Browse button  -  filedialog appears
4) click Desktop button on left hand side of file dialog  - changes to
Desktop location 
5) select a file from list and click Open (you can also double click on file
to select it doesn't matter) - path is displayed in Entry field
6) click Browse button again
7) click Desktop button again
8) Now here it is - slowly move cursor to a filename in the list - as soon
as cursor is over file the application shuts down.

My observations: 1) It takes two times selecting a file from the desktop for
this to happen.  2) It seems to happen on the second time as soon as the pop
up displays the file info (i.e. if you move cursor over a file, a pop up
appears with file type, date and size info).  3) This only happens when
selecting from desktop.  I can select files without any problems from any
other location.

You should determine whether this error happens with wish.exe as well as
with Python's Tkinter module.  If it does, please submit a bug report to 
    http://sf.net/projects/tktoolkit

Yes, this happens on wish.exe as well.
to repeat:
1) start Dos console and cd to C:\Tcl\demos\Tk8.4
2) at prompt enter: wish widget.tcl  - widget demonstration window opens
3) scroll to Common Dialogs and select 2. File selection dialog
4) click browse button in dialog
5) click Desktop button on left hand side of dialog
6) double click any .txt file - file path entered in entry field
7) click browse button again
8) click Desktop button again
9) just move cursor over a .txt file

The dialog is destroyed.  Note: this happens in XP, I wasn't able to
reproduce on Win 2000.
I will go ahead and log a bug.
