progressbar in Tkinter with a label inside
progress-bar, python, tkinter
Solution
I added the label inside the progressbar by creating a custom ttk style layout. The text of the label is changed by configuring the style:
from tkinter import Tk
from tkinter.ttk import Progressbar, Style, Button
from time import sleep
root = Tk()
s = Style(root)
# add the label to the progressbar style
s.layout("LabeledProgressbar",
[('LabeledProgressbar.trough',
{'children': [('LabeledProgressbar.pbar',
{'side': 'left', 'sticky': 'ns'}),
("LabeledProgressbar.label", # label inside the bar
{"sticky": ""})],
'sticky': 'nswe'})])
p = Progressbar(root, orient="horizontal", length=300,
style="LabeledProgressbar")
p.pack()
# change the text of the progressbar,
# the trailing spaces are here to properly center the text
s.configure("LabeledProgressbar", text="0 % ")
def fct():
for i in range(1, 101):
sleep(0.1)
p.step()
s.configure("LabeledProgressbar", text="{0} % ".format(i))
root.update()
Button(root, command=fct, text="launch").pack()
root.mainloop()
Problem
Is It possible to improve my progressbar in Tkinter-Python adding a label in the middle (ex: reading file)? I tried to find a elegant coding solution but without a real result ``` from Tkinter import * import ttk import tkFileDialog import time class MainWindow(Frame): def __init__(self): Frame.__init__(self) self.master.title("ProgressBar example") self.master.minsize(200, 100) self.grid(sticky=E+W+N+S) top = self.winfo_toplevel() top.rowconfigure(0, weight=1) top.columnconfigure(0, weight=1) self.start_ind = Button(self, text='Start indeterminate', command=self.start_ind, activeforeground="red") self.start_ind.grid(row=0, column=0, pady=2, padx=2, sticky=E+W+N+S) self.pbar_ind = ttk.Progressbar(self, orient="horizontal", length=300, mode="indeterminate") self.pbar_ind.grid(row=1, column=0, pady=2, padx=2, sticky=E+W+N+S) def start_ind(self): for i in xrange(50): self.pbar_ind.step(1) self.update() # Busy-wait time.sleep(0.1) if __name__=="__main__": d = MainWindow() d.mainloop() ```
