tkinter progressbar - linked to function?

Working example - you can see current value and max value in both types progressbars.

--

You can use self.var_ind.set() or self.var_det.set() in your function (inside class MainWindow) to update progressbar.

--

If your function is outside class you have to call it with self.var_ind or self.var_det as argument.

 your_function(self.var_det)

and inside function use it

 def your_function(progress):     progress.set(10) # set new value     progress.set( progress.get() + 23 ) # add 23 to current value

I use var_ind.set() and self.var_det.set() in BEGIN, SET 23, END to set new value.

--

If you have to set max in progressbar you will need add self.pbar_ind or self.pbar_det as argument too.

 your_function(self.var_det, self.pbar_det)

and inside function use it

 def your_function(progress, bar):     bar.config(maximum=200) # set max to 200     bar.step() # add 1 to current value     bar.step(23) # add 23 to current value     progress.set(10) # set new value     progress.set( progress.get() + 23 ) # add 23 to current value

EDIT: new example with more buttons:

(To create example I used part of code from Gianni Spear question Using the same progressbar in tkinter for several computation in Python)
