I'm programming a game sa my graduation project in school. Once the manager closes the game, I want the other users to have a pop up that the game is ended and a button to click on in order to continue.
I want the whole window (with all the widgets) to get darker (not totally black but darker). Everything besides the pop up and the "continue" button
Enyone has a clue what I can do? I searched on the Internet and found nothing :/
Not able to use ImageGrab on linux, here is my solution:
import tkinter as tk
import numpy as np
import time
import pyscreenshot as ImageGrab
from PIL import Image, ImageTk
def grab(widget):
box = (widget.winfo_rootx(), widget.winfo_rooty(), widget.winfo_rootx()+widget.winfo_width(), widget.winfo_rooty()+widget.winfo_height())
grab = ImageGrab.grab(bbox=box)
return grab
def darken(widget):
widget.overlay = ImageTk.PhotoImage(Image.fromarray(np.asanyarray(grab(widget))//2))
cvs = tk.Canvas(widget, width=widget.winfo_width(), height=widget.winfo_height())
cvs.place(x=0,y=0)
cvs.create_image(0, 0, anchor='nw', image=widget.overlay)
return cvs
root = tk.Tk()
def apply_dark():
cvs = darken(root)
b = tk.Button(root, text='Ok')
def d():
cvs.destroy()
b.destroy()
b.config(command=d)
b.place(x=50, y=10)
tk.Label(root, text='Label1').grid(row=0, column=0)
tk.Label(root, text='Label2').grid(row=0, column=1)
tk.Button(root, text='Button1').grid(row=1, column=0)
tk.Button(root, text='Darken', command=apply_dark).grid(row=1, column=1)
root.mainloop()
Fiddle around with this code. Of course this is in fact just a quick bodge (non-reliable, inefficient), but still - works for me.
Hope that's helpful!

I wonder if it's possible to insert an image or icon in the title of a Labelframe in tkinter ?
Maybe something like this lf = Labelframe(root, image='my_img'), the same as we can do with a button.
It would be very useful.
You can insert any widget as labelwidget option of LabelFrame.
If you want an image instead of text displayed in LabelFrame:
import tkinter as tk
from PIL import Image, ImageTk
w = tk.Tk()
w.geometry("400x500")
img_open = Image.open("example_1.png")
img = ImageTk.PhotoImage(img_open)
label_title = tk.Label(w, image=img) #important Do Not grid/pack/place it!
label_frame = tk.LabelFrame(w, labelwidget=label_title)
label_frame.grid(row=0, column=0)
#fill LabelFrame with something to make it visible
bt = tk.Button(label_frame, text="Press")
bt.grid(padx=20, pady=20)
w.mainloop()
Output:
Or like I said before you can use any widget.
An example label with image and a label with text.
import tkinter as tk
from PIL import Image, ImageTk
w = tk.Tk()
w.geometry("400x500")
img_open = Image.open("example_1.png")
img = ImageTk.PhotoImage(img_open)
frame_labelwidget = tk.Frame(w) #important Do Not grid/pack/place it!
label_image = tk.Label(frame_labelwidget, image=img)
label_image.grid(row=0, column=0)
label_text = tk.Label(frame_labelwidget, text="Teamwork")
label_text.grid(row=0, column=1)
label_frame = tk.LabelFrame(w, labelwidget=frame_labelwidget)
label_frame.grid(row=0, column=0)
#fill LabelFrame with something to make it visible
bt = tk.Button(label_frame, text="Press")
bt.grid(padx=20, pady=20)
w.mainloop()
Output:
Of course that makes less sense because you can have text and an image combined in tk.Label by using compound option.
I added it only for demonstration purpose, you can add any widget you want. Instead of label_text you could add an Entry, Canvas...
from tkinter import *
def printSomething():
inputValue=textBox.get("1.0","end-1c")
res=response(inputValue)
label = Label(root, text=res)
#this creates a new label to the GUI
label.pack()
root = Tk()
button = Button(root, text="Print Me", command=printSomething)
button.pack()
textBox=Text(root, height=2, width=10)
textBox.pack()
root.mainloop()
I have written a python code that returns text. and print that in tkinter label.while i try to execute it shows "None" in label.
It would probably be better to create the label in the global namespace once and then just update the label every time you press the button.
I also recommend using import tkinter as tk vs from tkinter import * as it provides better maintainability as your code grows and you do not end up overwriting built in methods.
I have updated your code and changed a few things to better fit the PEP8 standard.
import tkinter as tk
def print_something():
label.config(text=text_box.get("1.0", "end-1c"))
root = tk.Tk()
tk.Button(root, text="Print Me", command=print_something).pack()
text_box = tk.Text(root, height=2, width=10)
text_box.pack()
label = tk.Label(root)
label.pack()
root.mainloop()
Just changing your line:
res = response(inputValue)
to
res = inputValue
worked for me, creating a new label every time I pressed the button.
I've written a very simple app with python3, tkinter, but am seeing some strange behaviour with Entry(). I'm new to tkinter and python.
import os
from tkinter import Tk, Entry, filedialog
class MyGUI:
def __init__(self,master):
self.master = master
self.date_entry = Entry(master)
self.date_entry.pack()
self.date_entry.insert(0,"test")
self.master.mainloop()
root = Tk()
root.directory = os.path.abspath(filedialog.askdirectory())
my_gui = MyGUI(root)
When I run this code, the second to last line is what is causing the following problem:
When I try to edit the "test" text I cannot select it (no cursor or anything). However, if I click once away from the app (e.g. desktop) I can then edit it.
Does anyone know what the problem could be?
I was wondering if it's to do with a new app window being created by the filedialog, but I couldn't find an answer.
Thanks for your replies!
After testing this odd behavior a bit it appear as though as long as you add a button to get the directory the issue goes away.
I find it odd however and I will see if I can find anything that could explain why tkinter is acting like this.
This code should work for you:
import tkinter as tk
from tkinter import filedialog
class MyGUI(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self.date_entry = tk.Entry(self)
self.date_entry.pack()
self.date_entry.insert(0, "test")
self.directory = ""
tk.Button(self, text="Get Directory", command=self.get_directory).pack()
def get_directory(self):
self.directory = filedialog.askdirectory()
MyGUI().mainloop()
UPDATE:
I have recently learned that adding update_idletasks() before the filedialog will fix the focus issue.
Updated code:
import os
from tkinter import Tk, Entry, filedialog
class MyGUI:
def __init__(self,master):
self.master = master
self.date_entry = Entry(master)
self.date_entry.pack()
self.date_entry.insert(0,"test")
self.master.mainloop()
root = Tk()
root.update_idletasks() # fix focus issue.
root.directory = os.path.abspath(filedialog.askdirectory())
my_gui = MyGUI(root)
OK so i am trying to make a program that displays an image when pressing a button, and i am having trouble getting the images into the program
this is my full code:
# Nicolas Bart
import tkinter as tk
from PIL import Image, ImageTk
from tkinter import *
window = tk.Tk()
window.title('Bad Meme Generator')
window.geometry('500x500')
window.configure(bg='saddle brown')
meme_label = tk.Label(window, text='PRESS BUTTON FOR BAD MEMES:',
fg='blue4', bg='brown4', font=('comicsans', '20'))
meme_label.grid(pady=25, padx=25, column=0, row=0)
def button_command():
meme_window = tk.Tk()
meme_window.title('I Warned You')
meme_window.grid()
image = Image.open('pexels-photo-247932.jpg')
photo = ImageTk.PhotoImage(image)
label = tk.Label(meme_window, image=photo)
label.image = photo
label.place(x = 0, y = 0)
button = tk.Button(window, text='Dont Do It!', command=button_command,
padx=100, pady=75, font=('comicsans', '20'),
bg='brown4', fg='blue4')
button.grid(column=0, row=1)
warning_label = tk.Label(window, text="Really shit tier memes incoming:",
bg='brown4', fg='blue4',
font=('comicsans', '20'))
warning_label.grid(pady=75)
window.mainloop()
every time i run this program, when i press the button to open the image, it gives the error "AttributeError: type object 'Image' has no attribute 'open'"
the specific part of the program that is giving the error is:
def button_command():
meme_window = tk.Tk()
meme_window.title('I Warned You')
meme_window.grid()
image = Image.open('pexels-photo-247932.jpg')
photo = ImageTk.PhotoImage(image)
label = tk.Label(meme_window, image=photo)
label.image = photo
label.place(x = 0, y = 0)
any help would be appreciated. Thank you :)
This is a good example of why you shouldn't do from tkinter import *. Tkinter has an Image class, so by doing this import after importing Image from PIL you overwrite the PIL class with the tkinter class.
Since you're already importing tkinter the preferred way (import tkinter as tk), you don't need to import tkinter a second time. You need to remove the statement from tkinter import *.
You also make the mistake of creating more than one instance of Tk. I don't know if it contributes to the problem or not, but it's not something you should be doing. If you need additional windows then you should create instances of Toplevel.
I'm trying to change the color of a progress bar but the :
myProgressbar.configure(background="color")
It doesn't seems to work. I searched on the site, but didn't find an answer for the case of Tkinter.
Any idea ?
Thank you.
In python 2.7, you can do the same using theme. Here is the code:-
import Tkinter as tk
import ttk as ttk
root = tk.Tk()
frame = tk.Frame(root)
frame.grid()
s = ttk.Style()
s.theme_use('clam')
s.configure("red.Horizontal.TProgressbar", foreground='red', background='red')
ttk.Progressbar(frame, style="red.Horizontal.TProgressbar", orient="horizontal", length=600,mode="determinate", maximum=4, value=1).grid(row=1, column=1)
frame.pack()
tk.mainloop()
