I'm learning Tkinter now and have upgraded few programs I've made in CLI
in the past.
What is bothering me now is what I should look at when I want new
content in a window when button is 'Next' is clicked. In some programs
we're clicking button next and new content appears in same window.
I've used so far Toplevel(root) and new window was appearing on top the
main one but I'd like to find out about solution without creating new
windows. Is it a Canvas used for it?
I'd be glad if you could direct me because I don't know even what to
look for.
The trick is to put the "pages" on top of each other and then show the
appropriate one, something like this:
import tkinter as tk
def on_next_page():
# Brings page 2 to the top.
frame_2.tkraise()
def on_previous_page():
# Brings page 1 to the top.
frame_1.tkraise()
def on_finish():
# Closes the dialog.
root.destroy()
root = tk.Tk()
# Page 1.
frame_1 = tk.Frame(root)
tk.Label(frame_1, text='Page 1').pack()
tk.Button(frame_1, text='Next', command=on_next_page).pack()
# Page 2.
frame_2 = tk.Frame()
tk.Label(frame_2, text='Page 2').pack()
tk.Button(frame_2, text='Previous', command=on_previous_page).pack()
tk.Button(frame_2, text='Finish', command=on_finish).pack()
# Put the pages on top of each other.
frame_1.grid(row=0, column=0, sticky='news')
frame_2.grid(row=0, column=0, sticky='news')
# Bring page 1 to the top.
frame_1.tkraise()
tk.mainloop()
