import os
import Tkinter
gui = Tkinter.Tk()
gui.geometry("300x200")
messagebutton1 = Tkinter.Button(gui,text='Process Completed')
messagebutton1.place(x=80,y=80)
This is my example.I need to close this "process Completed" message button by clicking.What is the syntax for that.can you please guide me.
Use destroy method to close Tk.
import os
import Tkinter
def close():
gui.destroy()
gui = Tkinter.Tk()
gui.geometry("300x200")
messagebutton1 = Tkinter.Button(gui,text='Process Completed', command=close)
messagebutton1.place(x=80,y=80)
gui.mainloop()
My code works perfectly for image saved in same directory.

What changes should be made in this code if i want to take image from external source ie
Image:
source: "http://example.com/myimage.jpg"
Obviously this does not work. Please help.
Try using AsyncImage instead. From the documentation:
To load an image asynchronously (for example from an external
webserver), use the AsyncImage subclass:
aimg = AsyncImage(source='http://mywebsite.com/logo.png')
This can be useful as it prevents your application from waiting until
the image is loaded. If you want to display large images or retrieve
them from URL’s, using AsyncImage will allow these resources to be
retrieved on a background thread without blocking your application.
I am trying to make a scrollable label which has some text so here is my code
Here is my main.py
from kivy.app import App
import socket, sys, threading, os, time
class ExampleApp(App):
def build(self):
pass
if __name__ == "__main__":
ExampleApp().run()
Here is my example.kv file
ScrollView:
Label:
text:"hello world"*1000
I am facing issues with this....some one please post answer for this
I have a python script which has the functionality of sending an email to a user. I executed this script and it is working fine. In another python script I have only a button, so when I click on this button I want the other python script which sends a email to be executed.I have written the following code:
#!/usr/bin/python
import sys
import os
import Tkinter
import tkMessageBox
top=Tkinter.Tk()
def helloCallBack():
os.system('SendEmail.py')
B=Tkinter.Button(top,text="hello",command= helloCallBack)
B.pack()
top.mainloop()
I get the following error when I click on the button:
sh: 1:SendEmail.py:not found.
Could you let me know what is the reason for this error and how it can be resolved.Thanks.
I was able to figure out a way to call another python script on button click:
instead of using os.system('SendEmail.py') we need to use os.system('python SendEmail.py')
import sys
import os
from tkinter import *
window=Tk()
window.title("Running Python Script")
window.geometry('550x200')
def run():
os.system('opencv_video.py')
btn = Button(window, text="Click Me", bg="black", fg="white",command=run)
btn.grid(column=0, row=0)
window.mainloop()
If your SendEmail.py is in the same location, use os.system('SendEmail.py'). If it's in a different location, use os.system('python SendEmail.py').
#!/usr/bin/python
import sys
import sys
import os
import Tkinter
import tkMessageBox
top=Tkinter.Tk()
def helloCallBack():
os.system('python SendEmail.py')
B=Tkinter.Button(top,text="hello",command= helloCallBack)
B.pack()
top.mainloop()
use the keyword "python" to run the command
As an amateur, I am not really qualified to give advice. This is how I did it.
I want to do this kind of thing too. I have about 16 little python programs which make html, sets of checkboxes, sets of radiobuttons, text input fields, html tables etc.
In another thread here a comment was quite deprecative of using os.system calls. Not sure why, but I thought I would try another approach.
I've just started learning tkinter, so I am making each of my 'makehtml' functions run in a window.
Now I want a master window with buttons. Click a button and another window opens, say the checkboxes window, or any of the other windows for making html.
I made a module: guiHTML.py All my 'makehtml' functions are in there.
Import guiHTML in the master window.
import os, sys
# to import the files we need the paths
path = '/home/pedro/myPython/myModules/'
# append the paths
sys.path.append(path)
import tkinter as tk
from functools import partial
import guiHTML
Then, in the master window make a function like this for each button:
def openCheckboxes():
#call the checkboxes function defined in the guiHTML module
guiHTML.checkboxes()
Then, in the checkboxes button just put this:
btn3 = tk.Button(frame1, text='insert checkboxes', command=openCheckboxes)
btn3.grid(columnspan=2, column=0, row=2, sticky='w', pady=10)
Click btn3 and the checkboxes window opens.
This works for me, but I don't know if it is a good way to do this. I only began with tkinter a month ago.
If there is a better way to do this, I'd be glad to hear it from you experts!
#!/usr/bin/python
import sys
import os
import tkinter as tk
root = tk.Tk()
def helloCallBack():
os.system('call.py')
#Keep_both_files_in_the_same_Folder
b1=tk.Button(root, text="Calendar",bg="white",command=helloCallBack)
b1.pack()
root.mainloop()
I need to connect two python script class to each other and transfer values.
It seems that I made some mistakes to initialize the class objects and passing the
values please note the way I followed and somebody please kindly advise me on where I am getting wrong.
what is wrong with this line of code
def TransferTreeVal(objSubS):
objCM=MainScript.clsMain()
print "Transfer value"
Some more detailed code
##MainScript.py
import os
from Tkinter import *
import Tkinter as tk
import ttk
class clsMain():
def __init__ (objCM):
root['width']=500
root['height']=400
root['bg']='brown'
objCM.MethodDisplay()
def MethodDisplay(objCM):
print "display windows"
root=tk.Tk()
objCM = clsMain()
root.mainloop()
##SubScript.py
import os
from Tkinter import *
import Tkinter as tk
import ttk
import MainScript
class clsSubS():
def __init__ (objSubS):
root['width']=500
root['height']=500
root['bg']='brown'
objSubS.DispWin()
def TransferTreeVal(objSubS):
objCM=MainScript.clsMain()
print "Transfer value"
root=tk.Tk()
objSubS = clsSubS()
The main thing you are doing wrong is that you are importing files that have executable code in them. When you import SubScript.py, it is going to execute the code at the bottom which creates an instance of Tk. However, your main script also creates an instance of Tk and you should only ever have a single instance in a running program.
Normally, if you have a class you want to import, but you also want to use it as a standalone script, you "hide" the standalone script code behind a check like this:
if __name__ == "__main__":
root = tk.Tk()
objSubS = clsSubS()
With that, the code will only get executed if you do python SubScript.py. Also, when you import SubScript, that code will not run.
