Question

I’m doing a basic GUI to provide some user feedback after some shell commands, a little interface for a shell script really.

Showing a TK window, waiting for a os.system call to complete and updating the TK window multiple times, after each os.system call.

How does threading work with tk?

That’s it, thanks!

Answer 1

Just a basic example of what I did, with credit to Constantinius for pointing out that Thread works with Tk!

import sys, thread
from Tkinter import *
from os import system as run
from time import sleep

r = Tk()
r.title('Remote Support')
t = StringVar()
t.set('Completing Remote Support Initalisation         ')
l = Label(r,  textvariable=t).pack() 
def quit():
    #do cleanup if any
    r.destroy()
but = Button(r, text='Stop Remote Support', command=quit)
but.pack(side=LEFT)

def d():
    sleep(2)
    t.set('Completing Remote Support Initalisation, downloading, please wait         ')
    run('sleep 5') #test shell command
    t.set('Preparing to run download, please wait         ')
    run('sleep 5')
    t.set("OK thanks! Remote Support will now close         ")
    sleep(2)
    quit()

sleep(2)
thread.start_new_thread(d,())
r.mainloop()
