I have a GUI using Tkinter, it has a main screen and then when you press a button a popup window appears, where you select a checkbutton and then a email will get sent to you.
Not matter what I do, I cannot read the value of the checkbutton as 1 or True it always = 0 or False.
This is my code:
import tkinter as tk
from tkinter import *
import time
root = tk.Tk()
root.title('Status')
CheckVar1 = IntVar()
def email():
class PopUp(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
popup = tk.Toplevel(self, background='gray20')
popup.wm_title("EMAIL")
self.withdraw()
popup.tkraise(self)
topframe = Frame(popup, background='gray20')
topframe.grid(column=0, row=0)
bottomframe = Frame(popup, background='gray20')
bottomframe.grid(column=0, row=1)
self.c1 = tk.Checkbutton(topframe, text="Current", variable=CheckVar1, onvalue=1, offvalue=0, height=2, width=15, background='gray20', foreground='snow', selectcolor='gray35', activebackground='gray23', activeforeground='snow')
self.c1.pack(side="left", fill="x", anchor=NW)
label = tk.Label(bottomframe, text="Please Enter Email Address", background='gray20', foreground='snow')
label.pack(side="left", anchor=SW, fill="x", pady=10, padx=10)
self.entry = tk.Entry(bottomframe, bd=5, width=35, background='gray35', foreground='snow')
self.entry.pack(side="left", anchor=S, fill="x", pady=10, padx=10)
self.button = tk.Button(bottomframe, text="OK", command=self.on_button, background='gray20', foreground='snow')
self.button.pack(side="left", anchor=SE, padx=10, pady=10, fill="x")
def on_button(self):
address = self.entry.get()
print(address)
state = CheckVar1.get()
print (state)
time.sleep(2)
self.destroy()
app = PopUp()
app.update()
tk.Button(root,
text="EMAIL",
command=email,
background='gray15',
foreground='snow').pack(side=tk.BOTTOM, fill="both", anchor=N)
screen = tk.Canvas(root, width=400, height=475, background='gray15')
screen.pack(side = tk.BOTTOM, fill="both", expand=True)
def latest():
#Other code
root.after(300000, latest)
root.mainloop()
The popup works perfectly, and the email will print when entered but the value of checkbox is always 0.
I have tried:
CheckVar1 = tk.IntVar() - No success
self.CheckVar1 & self.CheckVar1.get() - No success
Removing self.withdraw() - No success
I only have one root.mainloop() in the script, I am using app.update() for the popup window because without this it will not open.
I have checked these existing questions for solution and none have helped:
Self.withdraw - Can't make tkinter checkbutton work normally when running as script
Self.CheckVar1 - TKInter checkbox variable is always 0
Only one instance of mainloop() - Python tkinter checkbutton value always equal to 0
I have also checked very similar questions but I wasn't going to post them all.
Any help is appreciated.
The problem is that you have two root windows. Each root window gets its own internal tcl interpreter, and the widgets and tkinter variables in one are completely invisible to the other. You're creating the IntVar in the first root window, and then trying to associate it with a checkbutton in a second root window. This cannot work. You should always only have a single instance of Tk in a tkinter program.
because of variable scope
try to put CheckVar1 = IntVar() inside the class
use it with self like this
self.CheckVar1 = tk.IntVar() # object of int
self.CheckVar1.set(1) # set value
variable=self.CheckVar1 # passing to the checkbutton as parameter
state = self.CheckVar1.get() # getting value

I am quite new with Tkinter and am trying to create a new window using this script while keeping the current window but i am get the error
_init_() missing 1 required positional argument: 'parent'. I am not really sure what the reason is but I am assuming that the command function for my button isn't working the way I want it.
The script currently looks something like this:
from tkinter import simpledialog
from tkinter import *
class Additional(simpledialog.Dialog):
def body(self, master):
#input fields
Label(master, text="Picture 3 Path:").grid(row=1)
#input fields for tags
#add as needed
self.e1 = Entry(master)
self.e1.grid(row=1, column=1, ipadx=150)
return self.e1 # initial focus
def apply(self):
first = self.e1.get()
self.ttag1 = (first)
class Initial(simpledialog.Dialog):
def body(self, master):
#input fields for username and passwords
Label(master, text="Usernames:").grid(row=1),
self.e1 = Entry(master)
self.b1 = Button(master, text = "Add More", bg= 'grey', command= Additional)
self.b1.grid(row=6, column=2, ipadx=75)
self.e1.grid(row=1, column=1, columnspan=2, ipadx=50)
return self.e1 # initial focus
def apply(self):
first = self.e1.get()
self.tag1 = (first)
root = tk.Tk()
root.withdraw()
d = Initial(root)
toor = tk.Tk()
toor.withdraw()
I have tried changing it up but it seems that it's not working right. Any ideas?
When calling the Additional class through the button command, you are not specifying what the parent root should be, and therefore the class fails to initiate. You can solve this by passing the master using a lambda
self.b1 = Button(master, text="Add More", bg='grey', command=lambda: Additional(master))
I been searching for methods to copy text to clipboard or copy the results from Tkinter gui but idk if there is a command or something
here is my code for now here the result comes in a messagebox can i copy it to clipboard
import tkinter.messagebox
import string
import random
def qs_msgbbox(): # qs_msgbbox
tkinter.messagebox.showinfo("Info", "For customer support or tip or rating contact:"
"dghaily725#gmail.com\npress the button for generated pass\nmsg will appear then copy\nthe generated password")
def gen_pass(k=9): # gen_pass
char = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890!##$%^&*"
password = ''
for i in range(9):
password += random.choice(char)
tkinter.messagebox.showinfo("Password", password)
root = Tk()
root.title("Password Generator")
lbl1 = Label(root, text="Generate Password", bd=2, relief=SUNKEN, height=5, width=50, bg='black', fg='white')
lbl1.configure(font=(70))
lbl1.grid(row=0, column=2)
lbl2 = Label(root, text='For more information press the Question mark', bd=2, relief=SUNKEN, fg='red')
lbl2.configure(font=(70))
lbl2.grid(row=0, column=0, pady=10)
btn1 = Button(root, text='Press to Generate', height=5, width=50, bg='grey', command=gen_pass)
btn1.configure(font=(70))
btn1.grid(row=1, column=2, padx=460, pady=50)
btn2photo = PhotoImage(file='question.png')
btn2 = Button(root, image=btn2photo, width=30, height=30, command= qs_msgbbox)
btn2.grid(row=0, column=1)
root.mainloop()
and also just a quick small question is it better to use classes or this form
Tkinter does have a function for that, simply just
from tkinter import Tk
root = Tk()
root.clipboard_clear()
root.clipboard_append("Something to the clipboard")
root.update() # the text will stay there after the window is closed
Hope I could help

The above answer is perfectly fine. Infact its the method to do it. I read the comments, He had mentioned that it could only take in string. That is completely false. It can also take in functions. For example..
import tkinter as tk
root = tk.Tk()
#creating a entry Widget.(Labels are fine as well)
entry = tk.Entry(root)
entry.pack()
#NOW if you want to copy the whole string inside the above entry box after you
typed in #
def copy ():#assign this function to any button or any actions
root.clipboard_clear()
root.clipboard_append(entry.get()) #get anything from the entry widget.
root.mainloop()
Hoping this was helpful
I use Tkinter for make a GUI. I have a window with 2 radiobutton ('Yes' and 'No'), but when I select one, it don't run the script :
root = Tk()
Button(root, text='TEST', command=root.quit).pack()
root.mainloop()
master = Tk()
v = IntVar()
Radiobutton(master, text='Yes', variable=v, value=0).pack()
Radiobutton(master, text='No', variable=v, value=1).pack()
Button(master, text='Exit', command=master.quit).pack()
master.mainloop()
print(v.get())
if v.get() == 0:
testy = Tk()
Label(testy, text='Bad').pack()
testy.mainloop()
else:
testn = Tk()
Label(testn, text='Bad').pack()
testn.mainloop()
If I don't have the first window, it works but with it, it don't.
Somebody know how to fix this problem ?
You have initiated several Tk() systems, but there should be only one.
If you want to get a new window then use Toplevel()
No code is executed after mainloop() except for events. The code continues to "flow" after mainloop only after closing the windows.
So here is your code with fixes:
from tkinter import *
root = Tk()
Button(root, text='TEST', command=root.quit).pack()
master = Toplevel()
v = IntVar()
def check_radio():
print(v.get())
if v.get() == 0:
Label(Toplevel(), text='Bad').pack()
else:
Label(Toplevel(), text='Good').pack()
Radiobutton(master, text='Yes', variable=v, value=0, command=check_radio).pack()
Radiobutton(master, text='No', variable=v, value=1, command=check_radio).pack()
Button(master, text='Exit', command=master.quit).pack()
root.mainloop()
Check carefully, I changed the parents of widgets and other changes.
Possible duplicate of tkinter radiobutton not updating variable, but seeing as this question was asked first the answer may make more sense here.
Make sure you are assigning a master to the IntVar like self.rbv=tk.IntVar(master) #or 'root' or whatever you are using):
import Tkinter as tk
import ttk
class My_GUI:
def __init__(self,master):
self.master=master
master.title("TestRadio")
self.rbv=tk.IntVar(master)#<--- HERE! notice I specify 'master'
self.rb1=tk.Radiobutton(master,text="Radio1",variable=self.rbv,value=0,indicatoron=False,command=self.onRadioChange)
self.rb1.pack(side='left')
self.rb2=tk.Radiobutton(master,text="Radio2",variable=self.rbv,value=1,indicatoron=False,command=self.onRadioChange)
self.rb2.pack(side='left')
self.rb3=tk.Radiobutton(master,text="Radio3",variable=self.rbv,value=2,indicatoron=False,command=self.onRadioChange)
self.rb3.pack(side='left')
def onRadioChange(self,event=None):
print self.rbv.get()
root=tk.Tk()
gui=My_GUI(root)
root.mainloop()
try running that, click the different buttons (they are radiobuttons but with indicatoron=False) and you will see it prints correctly changed values!
I'm running Python 2.7.9 on a Mac. I've been unable to figure out why it is when I run my programs that only the Entry Widgets highlight each time I hit the Tab key to move to the next widget. Following is some test code. When I run the script and hit the Tab key, the first entry field is highlighted. The next time I hit the Tab key, the second entry field is highlighted. However, when I hit the tab key to move to the Button Widget, the Button is receiving the focus but there is not highlight to visually indicate to the user the focus.
The OptionMenu widget is skipped altogether, which is also a mystery. Both the radiobutton and the checkbox receives focus, just like the button widget, and again no highlight is present.
I've tried a variety of .config() arrangements to no avail. What am I missing?
from tkinter import *
class App:
def __init__(self, master):
frame = Frame(master)
frame.grid()
#Tests to make sure that Button receives focus.
def yup(self):
print "yup"
entry1 = Entry(frame)
entry1.pack()
entry2 = Entry(frame)
entry2.pack()
button1 = Button(frame, text="Test")
button1.pack()
button1.bind('<Return>', yup)
var1 = IntVar()
c = Checkbutton(frame, text="Expand", variable=var1)
c.pack()
var2 = StringVar()
radio = Radiobutton(frame, text="Test", variable=var2, value=1)
radio.pack()
var3 = StringVar()
optionmenu1 = OptionMenu(frame, var3, "one", "two", "three")
optionmenu1.pack()
root = Tk()
root.geometry('400x400+0+0')
app = App(root)
root.mainloop()
It sounds like you need to configure OS X for "Full Keyboard Access" to allow Tab to focus on all UI controls (versus just text boxes and lists).
In Yosemite (10.10), this setting can be found under System Preferences > Keyboard > Shortcuts, and can be toggled with Control+F7. Note that has nothing to do with Python, and will occur system-wide.
EDIT
So after doing some more testing, there appears to be some issues with the actual highlighting of certain widgets using tk on a Mac. Below is a condensed version of your original sample with some minor modifications for simplicity.
import Tkinter as tk
import ttk # more on this in a minute
class App(tk.Frame):
def __init__(self, master):
tk.Frame.__init__(self, master)
self.master = master
entry1 = tk.Entry(self)
entry1.pack()
entry2 = tk.Entry(self)
entry2.pack()
button1 = tk.Button(self, text="Test", command=self.yup)
button1.pack()
def yup(self):
print("yup")
# ...
root = tk.Tk()
app = App(root).pack()
root.mainloop()
With full keyboard access enabled as previously mentioned, I can verify that the button does indeed receive focus: on the third tab, after the first two entry widgets, hitting <space> "clicks" the button and prints to stdout. However there is no visual indication that the button is selected.
Changing the button from a tk.Button to a ttk.Button "fixes" this, and does indeed show the normal "selection" frame around the button when tabbing through the UI.
button1 = tk.Button(self, text="Test", command=self.yup)
# change this to:
button1 = ttk.Button(self, text="Test", command=self.yup)
I have no idea why this is, and I don't know what the consensus about tkinter.ttk is, but I prefer ttk to "plain" tk as it seems to produce widgets which appear more "native" to OS X in my experience. Note I also removed the bind statement, and am reporting my result using the OS X default of space to activate UI elements with full keyboard access enabled.
More on ttk here. Note also that not all tk widgets have a ttk implementation, and that there are also some ttk widgets which do not exist in tk.
Lastly below find the "ttk" version of the original snippet.
import Tkinter as tk
import ttk
class App(ttk.Frame):
def __init__(self, master):
ttk.Frame.__init__(self, master)
self.master = master
entry1 = ttk.Entry(self)
entry1.pack()
entry2 = ttk.Entry(self)
entry2.pack()
button1 = ttk.Button(self, text="Test", command=self.yup)
button1.pack()
def yup(self):
print("yup")
# ...
root = tk.Tk()
app = App(root).pack()
root.mainloop()
Hope this helps.
Try changing the background and highlightbackground colors as below but the problem is possibly because of the way the program is indented --> run the second code block.
top=Tk()
## active background
Button(top, text="Quit", bg="lightblue", activebackground="orange",
command=top.quit).grid(row=1)
top.mainloop()
##--------------- note the 3 lines that have been changed ---------
class App:
## function was not indented
def __init__(self, master):
frame = Frame(master)
frame.grid()
entry1 = Entry(frame)
entry1.pack()
entry1.focus_set()
entry2 = Entry(frame)
entry2.pack()
button1 = Button(frame, text="Test")
button1.pack()
## function called incorrectly
button1.bind('<Return>', self.yup)
var1 = IntVar()
c = Checkbutton(frame, text="Expand", variable=var1)
c.pack()
var2 = StringVar()
radio = Radiobutton(frame, text="Test", variable=var2, value=1)
radio.pack()
var3 = StringVar()
optionmenu1 = OptionMenu(frame, var3, "one", "two", "three")
optionmenu1.pack()
Button(frame, text="Quit", bg="orange", command=master.quit).pack()
## function indented too far
#Tests to make sure that Button receives focus.
def yup(self, args):
print "yup"
root = Tk()
root.geometry('400x400+0+0')
app = App(root)
root.mainloop()
I want to open a MessageBox with several Checkboxes to choose some options.
The MessageBox works, but I cannot access the status of the checkboxes.
I can toggle the checkbox (access to the class works) but I am not able to get the status.
How can I get back the Checkboxes status in the main window?
How the program should work:
Main window can create ChooseBox
ChooseBox should give options to choose (here one Option for test example)
Mein window shall get status (tested here with the test button)
(working with python27 and windows - but on ubuntu it did not work neither)
#!/usr/bin/python3
# -*- coding: cp1252 -*-
from Tkinter import *
class ChooseBox(Tk):
def __init__(self):
Tk.__init__(self)
self.var = IntVar()
self.chk = Checkbutton(self, text="Option 1", variable=self.var)
self.chk.pack()
# Button to show the status of the checkbutton
button = Button(self, text='Show Stat',
command=lambda: self.Status(self.var))
button.pack()
def Status(self, var):
print var.get()
def message():
global Choose
Choose = ChooseBox()
Choose.mainloop()
def test():
global Choose
Choose.chk.toggle()
print Choose.var.get()
def main_wrapper(argv):
global Choose
root = Tk()
root.geometry("200x150+30+30")
Button_Frame=Frame(root)
Button_Frame.pack(side=BOTTOM, anchor=W, fill=X, expand=NO)
Button(Button_Frame, text='Make ChooseBox', command=message).pack(side=LEFT, anchor=W, padx=5, pady=5)
# Button to test access to the Box - here it toggles the Checkbutton and (should) prints the status
Button(Button_Frame, text='test', command=test).pack(side=LEFT, anchor=W, padx=5, pady=5)
Button(Button_Frame, text='Quit', command=root.quit).pack(side=RIGHT, anchor=E, padx=5)
root.mainloop()
if __name__ == '__main__':
main_wrapper(sys.argv)
You can not have two Tk() windows, the Tk window is unique and can only be called once. Instead replace the Tk in your choosebox with a Toplevel instead. Other than that I think it should work
