Tkinter Textbox内容倒置问题：修改insert('end')仍无法解决

Hey there! Let's figure out why your Tkinter Text widget is showing content in reverse order and fix it up.

The Root Problem #

Looking through your code, nearly every Text_Box.insert() call uses '1.0' as the insertion position. '1.0' tells Tkinter to add new text at the very start of the widget (line 1, character 0). So every time you log a new event, it gets placed before all existing content—naturally making everything show up upside down. Even though you changed one line to use 'end', all the other insertions are still pushing new text to the top, so the issue sticks around.

The Simple Fix #

You need to replace all instances of Text_Box.insert('1.0', ...) (including that random '1.4' in the error handling block) with Text_Box.insert('end', ...). This ensures every new log entry gets appended to the end of the widget, keeping your events in chronological order.

Here's a snippet of how your corrected Friendly_Output function would look for key sections:

def Friendly_Output(line,number,times):
    # Begin Searching
    if "viewDidLoad() - Got a valid" in line and Error == False:
        UserFile.write("\nFound mac address here")
        Text_Box.insert("end", "\nFound mac address here")  # Updated to append at end
    else:
        pass

    if Error == False and "wifiScanTimerEvent(timer:)" in line:
        UserFile.write("\nPinged nearby wifi with NIC " + str(times) + " time(s)")
        Text_Box.insert("end", "\nPinged nearby wifi with NIC " + str(times) + " time(s)")  # Updated to append at end
    
    # ... Repeat this change for EVERY Text_Box.insert call in the function ...

    # Fix the error handling section too:
    if "0110" in line:
        UserFile.write("\nERROR: No Bluetooth device was found")
        Text_Box.insert('end',"\nERROR: No Bluetooth device was found")  # Replaced '1.4' with 'end'
    elif "0120" in line:
        UserFile.write("\nERROR: No Wifi or Poor Connection")
        Text_Box.insert('end', "\nERROR: No Wifi or Poor Connection")  # Updated to append at end
    # ... Fix all error-related insertions the same way ...

Bonus Quality-of-Life Tip #

If you want the text widget to automatically scroll to the latest entry as it's added, add this line right after each insertion (or wrap it in a small helper function to avoid repetition):

Text_Box.see('end')

This ensures users always see the most recent log without having to manually scroll down.

Make these changes, and your text content should display in the correct order immediately!
