[Tkinter] How to get the result of a ping to show in tkinter?

[joe_momma]

thanks Yoriz and Deadeye for your examples. Yoriz I guess your using windows because to get it to work on linux I changed:

        result = os.popen("ping "+self.entry.get()+" -n 2")
        for line in result:
            self.insert_text(line)
 

to:

        result = os.popen("ping "+self.entry.get()+" -c 2")
        for line in result:
            self.insert_text(line)

no output other wise
DeadEye I got an attribute error:

Output:
File "/home/pi/tk_ping.py", line 53, in __init__
    self.ip.trace_add("write", self.validate)
AttributeError: 'StringVar' object has no attribute 'trace_add'

and changed this line in your __init__:

self.ip.trace_variable("w", self.validate)

then I got a type error:

Output:
File "/home/pi/tk_ping.py", line 102, in ping_thread
    stdout = check_output(['ping', '-c', '3', self.ip.get()], encoding="utf8")
  File "/usr/lib/python3.5/subprocess.py", line 316, in check_output
    **kwargs).stdout
  File "/usr/lib/python3.5/subprocess.py", line 383, in run
    with Popen(*popenargs, **kwargs) as process:
TypeError: __init__() got an unexpected keyword argument 'encoding'

so I deleted the keyword encoding and everything worked:

stdout = check_output(['ping', '-c', '3', self.ip.get()],)

fyi, Joe
