tkinter-entry

问题 I've written a very simple code with python tkinter , it contains an input box. I'd like to keep the value inserted by the user to myself, in case I need to use it later. Here's the code: import tkinter as tk root=tk.Tk() root.geometry("600x400") def submit(): name=name_entry.get() return name name_label = tk.Label(root, text = 'Username', font=('calibre', 10, 'bold')) name_entry = tk.Entry(root, font=('calibre',10,'normal')) sub_btn=tk.Button(root,text = 'Submit', command = submit) name

问题 I am trying to run a function concurrently over multiple files in a gui using tkinter and concurrent.futures Outside of the GUI, this script works fine. However, whenever I translate it over into the GUI script, instead of running the function in parallel, the script opens up 5 new gui tkinter windows (the number of windows it opens is equal to the number of processors I allow the program to use). Ive looked over the code thoroughly and just cant understand why it is opening new windows as

问题 Right now I'm working on a project that will ask for a runner's name, 1 mile, 2 mile, and 5 miles times and generate data based off that. The requirement is to have enough entries for 7 runners but I thought I'd add the ability to add any number of runners by using exec() . However, when trying to read data from the variables defined within them, I get a NameError: name 'entry2' is not defined but not for entry0 and entry1 , so I was wondering if anyone could help me out on these. In case it

问题 I'm trying to make a tkinter GUI with a certain amount of buttons and entry fields that is specified by the user, so in this code below for example if the user specifies the variable number to be 3 I want there to be 3 entry boxes and , and I want to set it up so that if I type a value into the first field and click the button next to it, I want that button to read the value from the entry field next to it. I also need to assign each entry field to a variable that will be created through the

问题 I've searched everywhere on the web but unfortunately no where did I find an answer to this question: after setting a tkinter Entry() widget's textvariable to a textvariable. the text variable does not update after I have typed text into the entry. code below: def saveFileName(self): if(self.save_file_name != ""): self.window.destroy() self.name_not_set = False print("saving...") else: print("notsaving...entry empty") pass def cancel(self): self.name_not_set = False self.exit = True self

问题 So I have Entries which have some values assigned to them from a CFG File. I want to modify the CFG file when the Entry is updated, live, without a submit button; Using <Key> binding will work but will take only the previous value, not the current one, as the last key pressed is not taken into consideration as a value, but as a key-press . For example: class EntryBox: def __init__(self, value, option, section, grid_row, master_e): self.section = section self.option = option self.box = Entry

问题 I want to make the program that I made can run i make code like this def cafe_food(self): friedrice_items = tk.Entry(F_FItems) friedrice_items.config(width=7, borderwidth=4, relief="sunken", font=("calibri", 10,"bold"),foreground="white", background="#248aa2") friedrice_items.place(x=81, y=1) def Total_Biil(self): friedrice_price = 10 pizza_price = 20 if friedrice_items.get() != "": friedrice_cost = friedrice_price * int(friedrice_items.get()) else: friedrice_cost = 0 if pizza_items.get() !=
