Resize sheet when user resize window about tksheet

[ragardner]

I think there are a few possible solutions, I'll start with the easiest

If you have put the Sheet() inside a frame using .grid() then you can try the code:

self.my_frame_name.grid_columnconfigure(<integer column that the Sheet() was put in>, weight = 1)
self.my_frame_name.grid_rowconfigure(<integer row that the Sheet() was put in>, weight = 1)

and don't forget to use sticky = when you use .grid()

Or if you used .pack() then you can try messing about with fill and expand as shown in this question:
https://stackoverflow.com/questions/28089942/difference-between-fill-and-expand-options-for-tkinter-pack-method

Try the above methods on other parent container frames as well and if you have set a specific width and height for the Sheet() you could try not doing that combined with the code above

I have also written some example code based on your image that might help, it seems to do what you want and might highlight what you need to change, but I'm not 100% sure it's applicable, give it a try:

from tksheet import Sheet
import tkinter as tk

app = tk.Tk()
app.grid_columnconfigure(0, weight = 1)
app.grid_rowconfigure(0, weight = 1)

main_frame = tk.Frame(app)
main_frame.grid(row = 0, column = 0, sticky = "nsew", padx = 10, pady = 10)

entry = tk.Entry(main_frame)
entry.grid(row = 0, column = 0, sticky = "ew", padx = 10, pady = 10)

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

sheet = Sheet(main_frame,
              total_rows = 1200,
              total_columns = 30)
sheet.grid(row = 1, column = 0, sticky = "nswe", padx = 10, pady = 10)
app.mainloop()

If these don't work or are not applicable let me know and I could get into .bind("<Configure>", ... stuff or alternatively if you pasted just the UI code I might be able to fix it
