You have to methodically determine on an event by event basis what is
going to cause selection and what isn't, then update the menus
accordingly. It takes a lot of testing. An alternative is polling
whether text is selected at the moment but is a waste of CPU cycles and
is unnecessary.
Best is to let the system clipboard handle copy-paste as it was designed
to do. You are opening a can of worms trying to micromanage your
application.

Bind the Button1-ButtonRelease event to a function which checks the
length of the SEL tag of the text widget. If it is zero length, disable
the appropriate menu entries, if it is non-zero, enable the appropriate
menu entries.
Simple example:
from Tkinter import *
root = Tk()
textWidget = Text(root)
textWidget.pack ()
def onButton1Releas e(event):
if len(textWidget. tag_ranges(SEL) ) == 0:
print 'No text selected. Disable appropriate menu entries'
else:
print 'Some text selected. Enable appropriate menu entries'
textWidget.bind ('<Button1-ButtonRelease>' , onButton1Releas e)
root.mainloop()

thx, but what i dont know is how to change state on menu item.
I dont know how to access that menu item later.
I know on button like
B = Button(root)
B.pack()
and later i change with B.config(blabla )
but on menu i have more items like
M = Menu(root)
i.add_command(l abel='one', command=show1)
i.add_command(l abel='two', command=show2)
M.add_cascade(l abel='File', menu=i)
how to change item: 'two'
Use the entry config method of the Menu widget:
i.entryconfig(' one', state=DISABLED)

As you add more items, say text lines, in Text widget, it gets too
slow and almost impractical to use on. Take idle for example. If the
text gets bigger(e.g. print
urllib.urlopen('http://www.amazon.com').read() ), it becomes too
sluggish to use as an "interactive" shell.
I have tried wxPython and it seems to have the same problem (from my
experience using PyCrust).
Is there any way to speed up Text widget, or should I look for another

i wrote a very simple tkinter demo program that uses menus, buttons,
labels, entries, frames and secondary toplevels.
it is a python version of a java program made by a colleague.
the user can create ("Scrivi") a record with his second name, first name
and date of birth, save ("Salva") the record to a file or read in

These work fine on Linux
s.const = {}
s.const = '%c' % (0xb0)
s.const = '%c' % (0xf7)
s.const = '%c' % (0xd8)
On WinXP the symbols for division and angle work fine.
But the symbol for degrees, a little circle, produces
a vertical bar in Tkinter Text box or Canvas.

Hi there,
I've got a tree control in Tkinter (using the ESRF Tree module) but I
can't get it to layout how I want it.
I'd like to have it so that it streches north/south (anchored to the top
and bottom), is of a fixed width and is anchored to the left hand side.
Here's my code (its derived from one of the examples from the ESRF web
site):

Hi all,
I'm a programming dabbler trying learn Python, and I've got a few
questions.
Mainly: Where can I find a good open-source library or tutorial
(preferably free) that explains how to easily manipulate text in a
tKinter window? Basically, I want to be able to do anything that HTML
can do (or close to it) but without the HTML. :-)

Hello:
Below I have included a stripped down version of the GUI I am working on.
It contains 2 dialog boxes - one main and one settings. It has the following
problems, probably all related, that I am hoping someone knows what I am
doing wrong:
1) Pressing the Settings.. Button multiple times, brings up many instances
of the Settings Panel. I just want it to bring up one. Is there an easy
way to do that?

Hi,
I'm writing a small text editor type application with Python 2.5 and
Tkinter. I'm using the Tk text widget for input and output, and the
problem is that when I try to save its contents to a .txt file, any
Scandinavian letters such as "äöå ÄÖÅ" are saved incorrectly and show up
as a mess when I open the .txt file in Windows Notepad.
It seems that the characters will only get mixed if the user has typed
them into the widget, but if...
