I'm currently making a small application where I want the user to input some data, but there is an optional input. I want to use a checkbutton for that. If it is checked, the UI should show more input boxes and if it is unchecked, then the UI should hide them.
I'm using the newest version of anaconda-spyder and set the graphic backend in spyder to be tkinter
This is what I tried so far:
import tkinter as tkwindow=tk.Tk()frame_a=tk.Frame(window)frame_b=tk.Frame(window)frame_c=tk.Frame(window)entry1=tk.Entry(frame_a, width=10)entry1.pack()var1=tk.IntVar()checkbtn=tk.Checkbutton(frame_b, text="more options?", variable=var1, onvalue=1, offvalue=0)checkbtn.pack(side=tk.TOP)if var1.get() ==1: entry2=tk.Entry(frame_c, width=10) entry2.pack() frame_a.pack() frame_b.pack() frame_c.pack()else: frame_a.pack() frame_b.pack()window.mainloop()I assumed that the state of the checkbutton gets checked within the mainloop, but it seems to only get checked at the start of the program.
Alternatively if the checkbutton is unchecked the other option could be grayed out/not interactable, but still visible (i don't know if that makes it easier or not)
