I was running this code and it is supposed to be creating a window but it doesn't create any window in Pycharm. I am using Pycharm Community edition with Python 3.6. When I am running this code in IDLE, the window is generated.
import tkinter
from datetime import date, datetime
root = tkinter.Tk()
c = tkinter.Canvas(root,width =800, height =768, bg = 'black')
c.pack()
c.create_text(100,50, anchor = 'w', fill = 'orange', \
font = 'Arial 28 bold underline', text = 'My Countdown calendar')
Regular python shell and IDLE supports using tk without a mainloop. This is done by several hooks, installed when a tkapp object is being initialized, which handles Tk events while the shell is waiting for user input. However pycharm does not support this. So inorder to diplay your window using pycharm, you have to call
root.mainloop()
at the end.

I have prepared some tk application. It could be really simple like:
from tkinter import *
# create root window
root = Tk()
# root window title and dimension
root.title("Welcome to GeekForGeeks")
# Set geometry (widthxheight)
root.geometry('350x200')
# all widgets will be here
# Execute Tkinter
root.mainloop()
I have using some method to convert the app to the exe file.
What is important,
I'm not using and I cannot do it with pyinstaller py2exe etc. I also cannot use method with changing my app.py to app.pyw.
But my conversion to .exe is working correctly.
The question - is it even possible to hide/disable/resize(reduce the size) of my console window and make the application still working?
I'm not exactly sure how is it done in pyinstaller py2exe etc, so maybe is it possible to do it inside an application?
All right, to solve above problem install:
pip install pywin32
and add code before running your tk gui application:
import win32gui
import win32.lib.win32con as win32con
the_program_to_hide = win32gui.GetForegroundWindow()
win32gui.ShowWindow(the_program_to_hide , win32con.SW_HIDE)
Then you can run the main.py in console, the console will disappear and the gui app will be still visible.
In case when you use pyinstaller etc - you can convert the application without "--noconsole" argument.
When you run the .exe file the console will appear for a second, and disappear. But the gui app will be still visible and usable.
Hope it help somebody somehow :)
I think you should run your script using pythonw.exe instead of python.exe. See .pyw files in python program
Does this help if using Toplevel?
from tkinter import *
root = Tk()
root.title("Main Window")
root.geometry("200x200")
def launch():
global second
second = Toplevel()
second.title("Child Window")
second.geometry("400x400")
def show():
second.deiconify()
def hide():
second.withdraw()
Button(root, text="launch Window", command=launch).pack(pady=10)
Button(root, text="Show", command=show).pack(pady=10)
Button(root, text="Hide", command=hide).pack(pady=10)
root.mainloop()
I'm making a simple GUI using Python 3.7.3 and tkinter to open and close windows applications. I'm not able to find a way to close a running program using an onscreen button. I need the 'close' button to do something else as well, hence the simply using 'x' button (which is next to the minimize and maximize) won't work for my case.
from tkinter import *
import os, subprocess
root = Tk()
root.geometry("300x300")
def OpenCalc():
app1 = os.startfile("C:\Windows\System32\calc.exe")
def CloseCalc():
os.close(app1)
# or
# os.closefile("C:\Windows\System32\calc.exe")
b1=Button(root, text="Open Calc", command=OpenCalc).pack()
b2=Button(root, text="Close Calc", command=CloseCalc).pack()
root.mainloop()
Whenever I run the following snippet (on MacOs 10.13.1 using Python 3.6.1):
import tkinter
window = tkinter.Tk()
open_file = tkinter.Button(window, text="1", font=("Wingdings", 12))
open_file.pack()
Instead of showing the following glyph:
The program shows this:
Is there a way in which I can fix this so that the Wingdings font displays correctly?
(Note: The font shows up fine on Windows 10)
While building a basic app using the winapi with Python 2.7 (I'm on Windows 8.1), I tried to add a small Tkinter gui to the program. The problem is, whenever I close the app window, Python crashes completely (getting crash messages basically).
I have found reports of this issue in several places, but couldn't find a fix or solution. Here are some sources:
http://sourceforge.net/p/pywin32/bugs/443/#8bde
http://www.gossamer-threads.com/lists/python/python/134956 (this one is from 2002!)
It can be reproduced with as much as these 4 lines:
from Tkinter import Tk
import win32ui
root = Tk()
root.mainloop()
And closing the window after running it.
Does anyone know of a solution for this? Any recommendations for a workaround maybe?
A workaround is to invoke the Tkinter-win32UI app with pythonw. Python doesn't crash.
Tested with Python 3.6.3 on Win 10.
Make a button on the Windows and close your program by this button. Here's my script:
from tkinter import *
import win32ui
win = Tk()
frame = Frame(win)
frame.pack(padx = 10, pady = 10)
b1 = Button(frame, text = "Close", command = win.destroy)
b1.pack()
win.mainloop()
I looked through a tutorial on using Tkinter and saw that the following code:
>>> from Tkinter import *
>>> win=Tk()
This should produce a box with the title Tk and nothing else. However, when I try this code out no such box appears. I'm not getting any errors so I suspect it's working as intended. Is it possible that there are additional steps I have to take if I'm on a mac?
from Tkinter import *
root = Tk()
w = Label(root, text="Hello, world!")
w.pack()
root.mainloop()
This code runs automatically, however, in the guide it suggests that I use $ python hello1.py to run this code, which doesn't work. Any ideas on why this might be?
However, this larger block does not work:
from Tkinter import *
class App:
def __init__(self, master):
frame = Frame(master)
frame.pack()
self.button = Button(
frame, text="QUIT", fg="red", command=frame.quit
)
self.button.pack(side=LEFT)
self.hi_there = Button(frame, text="Hello", command=self.say_hi)
self.hi_there.pack(side=LEFT)
def say_hi(self):
print "hi there, everyone!"
root = Tk()
app = App(root)
root.mainloop()
root.destroy() # optional; see description below
The issue seems to have something to do with mainloop but I'm confused because at the same time that earlier block worked just fine with a root.mainloop() part.
Do you run this code in IDLE?
Try above code in terminal (not in IDLE), then it will work as expected.
So if you want to try and run it in Terminal you should follow the steps below
note- 'I find that running programs is Terminal that involve a tkinter Gui will often crash for me, however it may work for you'
1st - Open Terminal
2nd - Type 'python3.4' then press space bar once
3rd - Open a Finder window
4th - Go to where you saved your python file in the Finder window
5th - Once you have located the file in Finder, drag the file into the Terminal window
6th - Press enter, and enjoy your python program.
another note - 'It sounds like you need a better Python IDE, you should try out PyCharm it is a great Python IDE which you can code and run python programs in including tkinter stuff'
