root = tk.Tk() app = Application(root) The program would run as well as it did before. With all this in mind, what I'm interested in knowing is: What does calling root = tk.Tk() actually do (as in, what gets initialized) and why can the previous snippet work without it? Would I run into any pitfalls or limitations if I don't call Tk() and just built my application around the Frame class?
So appearantly many seems to have had this issue (me including) and I found the fault to be that Tkinter wasn't installed on my system when python was compiled. This post describes how to solve the problem by: Removing the virtual environment/python distribution install Tkinter with sudo apt-get install tk-dev (for deb) or sudo pacman -S tk (for arch/manjaro) Then proceed to compile python ...
I can't figure out if it's about root = tkinter.Tk() vs root = Tk(), or import tkinter vs from tkinter import *, or something entirely different. I can't find a successful combination. I'm using Ubuntu and Python 3.6.9.
The widgets in tkinter are highly and easily configurable. You have almost complete control over how they look - border widths, fonts, images, colors, etc. ttk widgets use styles to define how they look, so it takes a bit more work if you want a non-standard button. ttk widgets are also a little under-documented. Understanding the underlying theme and layout engines (layout within the widgets ...
package require tk frame .f button .f.b -text "Press me!" (note: Tkinter actually generates more complex names than .f and .f.b, but the concept is the same) The call method is the interface to this underlying tcl interpreter. It allows you to construct a tcl command and ask the interpreter to run it. It is a bridge between python and tcl. It is not typically used in application-level code ...
import Tkinter as Tk win = Tk.Toplevel() frame = Tk.Frame(master=win).grid(row=1, column=1) button = Tk.Button(master=frame, text='press', command=action) The method action is called when I press the button, but what if I wanted to pass some arguments to the method action? I have tried with the following code:
In case you are using a virtual environment on Windows, I have found a solution here. In a nuthsell: Copy the tcl/ folder from the Python root, e.g. C:/Python27/, to the root of the virtual environment, e.g. .venv/. Then Tkinter.Tk() shows a new window without throwing an exception. This was conducted with Python 2.7 on Windows 7, but still works in 2024. For instance, I encountered the same ...
For some reason, I can't use the Tkinter (or tkinter, on Python 3) module. After running the following command in the python shell: import Tkinter or this, in Python 3: import tkinter I got this ...
I have noticed that both of the instructions tk.Tk() and tk.Frame make a new window, so what is the difference between them? and what is the advantage of using one over the other ?
