问题 I'm trying to add a menu into the UI but it doesn't show up. I copied everything directly from effbot.org/tkinterbook/menu.htm but it still isn't working. I'm using Python 3 and macOS 10 if that's relevant. from tkinter import * master = Tk() master.geometry('300x300') master.title('Table') def hello(): print("hello") menubar = Menu(master) menubar.add_command(label = "Hello!", command = hello) menubar.add_command(label = "Quit!", command = master.quit) master.config(menu=menubar) master

问题 So I've written a python script that uses the PIL library to format a png passed to it. I want to make the script more user friendly and after looking around I saw the Tkinter library which seemed perfect. Basically the script has five variables that I need to pass to it for it to run.

I've used

问题 from the following code, I could update the line by clicking the "replot" button. I have to use both set_data() and also plot a new plot, otherwise the old plot is still here. However, I want the program automatically to update the curve inside of animate(), I use a 5 secs control to trigger replot() function, but it fails. if I do not use blit=True, just use blit=False, then everything is fine. Then my question is how to update the curve in animation triggered by condition, and also need to

问题 I recently read on of the answers written by respected Bryan Oakley(Tkinter adding line number to text widget) where he showed a sample code about solving the problem. When I tried working on that code & it worked correctly till I copy or paste something, i.e. I press Ctrl+C or Ctrl+V . It closed the tkinter window with the following error: _tkinter.TclError: text doesn't contain any characters tagged with "sel" Here is the code: import tkinter as tk class TextLineNumbers(tk.Canvas): def _

问题 I have a tree view in one of my tkinter app and i wanted to know if it really is possible to actually, just copy a selected field on right-clicking by the user.
