Let's walk through the issues in your current code and fix them to get your progressbar working exactly as you want:

Key Problems in Your Existing Code #

• You're incorrectly using self.after(100, self.textFileCreation()) — the parentheses mean you're running the function immediately instead of passing it as a callback to after().
• The self.process variable isn't initialized, so it might start from an unexpected value when you launch the progressbar.
• The progress update loop doesn't cleanly stop once the maximum value is hit.

Step 1: Initialize Progress Variables #

Add this to your class's __init__ method to ensure we always start from 0:

def __init__(self, master):
    # ... your existing initialization code ...
    self.process = 0  # Initialize progress counter to 0
    self.progressbar = ttk.Progressbar(self, orient="horizontal", length=300, maximum=100, mode="determinate")
    self.progressbar.place(x=250, y=225)

Step 2: Fix the Progress Update Function #

Here's the corrected textFileCreation function with proper auto-stop and post-completion logic:

def textFileCreation(self):
    # Update progress value
    self.process += 10
    self.progressbar['value'] = self.process

    if self.progressbar['value'] >= self.progressbar['maximum']:
        # Progress complete: run your post-completion actions
        msg_success = f"The file {self.dataName}.ctm has been created in the folder: {self.dataDirectory}"
        messagebox.showinfo("success", msg_success)
        create_file(self.dataPath, self.dataName, self.dataDirectory)
        # Reset progress for future launches
        self.process = 0
        return
    else:
        # Schedule next progress update (no parentheses after the function name!)
        self.after(100, self.textFileCreation)

Step 3: Reset Progress Before Launching #

In your launchCallBack function's else block, add lines to reset the progressbar so each launch starts fresh:

else :
    # Reset progress counter and bar before starting
    self.process = 0
    self.progressbar['value'] = 0
    self.textFileCreation()

What This Fixes #

• The progressbar now increments smoothly every 100ms until it reaches 100.
• Once it hits the maximum, it automatically stops updating, shows the success message, and runs your create_file function.
• Every time you click the launch button, the progress starts from 0 instead of picking up where it left off.
