RE: status bar to return to the centre after 1 minute of clicking a button ? - chano - May-21-2019

Hello,can you tell me how the statuss bar after i move with button to return it alone after 1 minute in centre.Thank you
import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()

progressbar = ttk.Progressbar(root, length=200, maximum=10, value=5)
progressbar.grid(row=1)

process = tk.IntVar(value=5)
def add_water():
    if process.get() < progressbar['maximum']:
        process.set( process.get() + 1)
        progressbar['value'] = process.get()

def sub_water():
    if process.get() > 0:
        process.set( process.get() - 1)
        progressbar['value'] = process.get()

add = ttk.Button(root, text='Water +', command=add_water)
sub = ttk.Button(root, text='Water -', command=sub_water)

label = ttk.Label(root, textvariable=process)

label.grid(row=0)

RE: RE: status bar to return alone on the centre - woooee - May-21-2019

We don't know what value is centre on your Progressbar. So generally I think something like this will work.
def return_to_centre():
    process.set(centre_value)

def add_water():
    if process.get() < progressbar['maximum']:
        process.set( process.get() + 1)
    else:
        process.after(1000*60, return_to_centre)  ## 60 seconds

You are much better off programming GUI's with classes, easier to organise and access attributes.
Using the after method allows the calling of a function after an amount of milliseconds.
I have a forum thread a bout using after https://python-forum.io/Thread-Tkinter-How-to-deal-with-code-that-blocks-the-mainloop-freezing-the-gui

The return of after gives an id that can be used to cancel a call,
that way if a button is pressed again before the call is made it will cancel the current one and a new after 1 minute call can be made.

See the following modified code.
import tkinter as tk

            self.after_cancel(self.after_id)

        self.after_id = self.after(delay_ms, self.reset_water)

    def add_water(self):
        progress_value = self.process.get()

            self.process.set(progress_value + 1)
            self.reset_after(60000)

    def sub_water(self):
        progress_value = self.process.get()
        if progress_value > 0:
            self.process.set(progress_value - 1)

You cant just paste my class methods into your function code, your code either needs turning into classes or my code needs re-organising into your functions
