问题 I am using Tkinter to build a Corona Travel History Questionnaire. The front end has options to select a particular date - " D-Day Cronoa Confirmed". Once the D-day is confirmed, the program is supposed to give fields for entering data on travel history. I am using tkcalendar module in Python. Problem: How to print the previous 30 days from a given date in python? Question: Can we do anything in tkcalendar to print the last 30 days from a selected date in the window itself? 回答1: Using the

问题 If you uncomment the options_frame_title you will see that it does not behave properly. Am I missing something? That section was just copied and pasted from the preview_frame_title and that seems to have no issues. from tkinter import * blank_app = Tk() blank_app.geometry('750x500+250+100') blank_app.resizable(width=False, height=False) main_frame = Frame(blank_app, width=750, height=500, bg='gray22') main_frame.grid(row=0, column=0, sticky=NSEW) main_title = Label(main_frame, text='App

问题 I made an application with tkinter which creates a list of checkboxes for some data. The checkboxes are created dynamically depending on the size of the dataset. I want to know of a way to get the input of each specific checkbox. Here is my code, which you should be able to run. from tkinter import * root = Tk() height = 21 width = 5 for i in range(1, height): placeholder_check_gen = Checkbutton(root) placeholder_check_gen.grid(row=i, column=3, sticky="nsew", pady=1, padx=1) for i in range(1,

问题 I want to add a hover feature on a Tkinter button where if the user hovers the mouse cursor then description text displays. I also want to add some delay for that description to appear so that it would not be intrusive. I can try using the "<Enter>" and "<Leave>" binding of the button to a function and make some "Label" appear in some corner of the app. But this approach may not be the most elegant. 回答1: Here is a small snippet using Pmw (python mega widgets) for the tool tips. Firstly start

问题 I am writing a python app to take some inputs from the user and call a shell script based on these inputs. This shell script can run for quite sometime, and I want to redirect the output it produces (in realtime) to tkinter. I managed to do that, but it only happens after the shell script is completely finished, not as soon as the shell script "echos" something for example. So main problem: 1. Output appears in the text widget only after shellScript.sh is exited (although if I run the same in
