Create a canvas and a vertical scrollbar
canvas = ttk.Canvas(root, width=root.winfo_screenwidth(), height=root.winfo_screenheight())





Create a frame inside the canvas
master_window = ttk.Frame(master=canvas, )
master_window.bind(" Configure ", lambda e: on_frame_configure(canvas))

Pack the frame into the canvas and center it horizontally
canvas.create_window((root.winfo_screenwidth() // 2, 0), window=master_window, anchor="n")
canvas.grid(row=1, column=1, rowspan=6, padx=0, pady=0)
scrollbar = ttk.Scrollbar(master=root, orient="vertical", command=canvas.yview)

root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)

Track the entries in a dictionary keyed by the row number

Reset the scroll region to encompass the inner frame
canvas.configure(scrollregion=canvas.bbox("all"))

Create a new Entry widget for the given row

def generate_workers():
global worker_entries # Declare global at the start of the function

Destroy all previous widgets in the generated frame
for widget in generated_frame.winfo_children():

Reset the max_entries dictionary and worker names list
max_entries.clear()
worker_entries.clear() # Clear the list to avoid old entries
workers_data.clear()
workers_list.clear() # Clear the worker data list
Clear the worker data list

Generate labels and entries for each worker

untested_label = ttk.Label(master=generated_frame, text="❌", font="Calibri 15")
