Get data out of a tcltk function

由 依然范特西╮ 提交于 2019-12-18 06:19:20
问题 This is probably so simple I will cringe when the answer comes back but I am totally stumped. I have tried the manuals, tried searching the web, assorted examples and anything else I can think of. I am still stuck. I am trying to create a simple input for the user to add two values I can then use in the rest of the R script. I need the script to pause and wait for the input from the user and then continue along once it gets the input (like how the choose file function works). AFter reading a

Python 3 Tkinter - Messagebox with a toplevel as master?

由 ↘锁芯ラ 提交于 2019-12-18 04:52:46
问题 I've found that when a toplevel widget calls a messagebox dialog (like "showinfo"), the root window is showed up, over the toplevel. Is there a way to set the Toplevel window as the master of the messagebox dialog ? Here is a script to reproduce this : # -*- coding:utf-8 -*- # PYTHON 3 ONLY from tkinter import * from tkinter import messagebox root = Tk() root.title('ROOT WINDOW') Label(root, text = 'Place the toplevel window over the root window\nThen, push the button and you will see that

Tkinter: windows without title bar but resizable

问题 What I know is if I want to create a window without title bar, I can write root = Tk() ........ root.overrideredirect(1) But I would also like the window to be resizable. Is there any solution? (FYI: I am working on Windows machine, although I am not sure if it really matters. It will be perfect if there is OS-independent solution, but I am happy if there is at least a solution for Windows first.) 回答1: The problem is, the window is resizable, but when you turn on overrideredirect you lose any

问题 I don't know how to explain this, actually I'm looking for the explanation, so I'll just mention some steps to reproduce the issue. Hopefully someone will be able to understand and elaborate: Python 3.5.0 on Windows 8.1. (However this should be reproducible regardless of Python and Windows version.) Having Persian standard keyboard Installed. (It can be downloaded from here. Again I'm sure the problem is not limited to this specific keyboard and there are some characters in some other

问题 I have a general question about how to effectively load any kind of external package into R. I have found that many sources detailing this information are simply insufficient, but I will leave out mentioning those respective URLs. I have successfully loaded external packages into R before, but I am having difficulties loading the fgui package. In my specific case, I cannot load the library fgui into R Studio. First I download directly from CRAN with the command: install.packages("fgui", lib="

Why are multiple instances of Tk discouraged?

问题 Consider below example: import tkinter as tk root = tk.Tk() root.title("root") other_window = tk.Tk() other_window.title("other_window") root.mainloop() and also see below example that creates instances of Tk back-to-back instead of at once, so there's exactly one instance of Tk at any given time: import tkinter as tk def create_window(window_to_be_closed=None): if window_to_be_closed: window_to_be_closed.destroy() window = tk.Tk() tk.Button(window, text="Quit", command=lambda arg=window :
