You can find ttk.Progressbar at tkdocs
from tkinter import *
from tkinter.ttk import *
tk=Tk()
progress=Progressbar(tk,orient=HORIZONTAL,length=100,mode='determinate')
def bar():
import time
progress['value']=20
tk.update_idletasks()
time.sleep(1)
progress['value']=50
tk.update_idletasks()
time.sleep(1)
progress['value']=80
tk.update_idletasks()
time.sleep(1)
progress['value']=100
progress.pack()
Button(tk,text='foo',command=bar).pack()
mainloop()
It’s better to use threading and run your code in another thread.
Like this:
from tkinter import Button, Tk, HORIZONTAL
from tkinter.ttk import Progressbar
import time
import threading
class MonApp(Tk):
def __init__(self):
super().__init__()
self.btn = Button(self, text='Traitement', command=self.traitement)
self.btn.grid(row=0,column=0)
self.progress = Progressbar(self, orient=HORIZONTAL,length=100, mode='indeterminate')
def traitement(self):
def real_traitement():
self.progress.grid(row=1,column=0)
self.progress.start()
time.sleep(5)
self.progress.stop()
self.progress.grid_forget()
self.btn['state']='normal'
self.btn['state']='disabled'
threading.Thread(target=real_traitement).start()
if __name__ == '__main__':
app = MonApp()
app.mainloop()
