How to enable/disable (cut, copy etc.) when text is selected/not
selected
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 onButton1Release(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', onButton1Release)
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(label='one', command=show1)
i.add_command(label='two', command=show2)
M.add_cascade(label='File', menu=i)
how to change item: 'two'
Use the entry config method of the Menu widget:
i.entryconfig('one', state=DISABLED)

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 *

textWidget.pack()
def onButton1Release(event):
if len(textWidget.tag_ranges(SEL)) == 0:

textWidget.bind('Button1-ButtonRelease', onButton1Release)
