Python

Building GUI with Python and Tk

Post author By masnun

I have been looking for a decent GUI toolkit to develop some desktop programs. I worked with Java. Didn’t like the idea of typing that much to develop a app. Used php with WinBinder and PHP-GTK. Liked the first one, but the binary I have won’t load the winbinder extension. To use it, I will have to go back to php4. Again I don’t like the idea of using php4 for GUI while using php5 for web development. So again I had to make a swtich. This time I went for wxPython for Python 2.6.0. Alas, though wxPython used to work fine on my XP, it no longer runs on Windows Vista.

Finally, I deceided to work with TK which comes pre-installed with Python. The IDLE, Module Docs and other GUI tools which comes with a standard Python installations are most often developed using TK on Python.

I liked TK quite a bit because the process of developing TK GUI apps are damn easy and great fun. While learning TK, I converted my old console twitter publisher to a TK powered GUI app. Here’s the sourcecode:

Python 3 Source Code:

import tkinter
root = tkinter.Tk();
root.title("maSnun")
mainFrame = tkinter.Frame(root)
topFrame = tkinter.Frame(mainFrame)
resFrame = tkinter.Frame(mainFrame)
topFrame["height"] = 50
topFrame["width"] = 400
inputBox = tkinter.Entry(topFrame)
okButton = tkinter.Button(topFrame)
okButton["text"] = "OK"
okButton["fg"] = "white"
okButton["bg"] = "black"
label = tkinter.Label(resFrame)
label.pack({"side":"top"})
label["text"] = ""
def ok_act():
	global label,inputBox
	import sys;
	from urllib.request import urlopen,Request;
	import base64;

	username = "username";
	password = "password";
	url = "http://www.twitter.com/statuses/update.xml";
	status = inputBox.get();
	data ="status="+status;
	req = Request(url);
	req.data = data;
	req.headers['Authorization'] = 'Basic %s' %  (base64.b64encode((username + ":" + password).encode())).decode();
	# req.headers['User-Agent'] = 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.20) Gecko/20081217 Firefox/2.0.0.20';
	urlopen(req);
	label["text"] = "Tweet Published!!"
	label.pack({"side":"top"})


okButton["command"] = ok_act
inputBox.pack({"side":"left"})
okButton.pack()
topFrame.pack({"side":"top"})


topFrame.pack({"side":"top"});
resFrame.pack({"side":"top"})
mainFrame.pack()
root.maxsize(400,400)
root.minsize(400,400)
root.mainloop();

import tkinter

root = tkinter.Tk();

root.title("maSnun")

mainFrame = tkinter.Frame(root)

topFrame = tkinter.Frame(mainFrame)

resFrame = tkinter.Frame(mainFrame)

topFrame["height"] = 50

topFrame["width"] = 400

inputBox = tkinter.Entry(topFrame)

okButton = tkinter.Button(topFrame)

okButton["text"] = "OK"

okButton["fg"] = "white"

okButton["bg"] = "black"

label = tkinter.Label(resFrame)

label.pack({"side":"top"})

label["text"] = ""

def ok_act():

global label,inputBox

import sys;

from urllib.request import urlopen,Request;

import base64;

username = "username";

password = "password";

url = "http://www.twitter.com/statuses/update.xml";

status = inputBox.get();

data ="status="+status;

req = Request(url);

req.data = data;

req.headers['Authorization'] = 'Basic %s' % (base64.b64encode((username + ":" + password).encode())).decode();

# req.headers['User-Agent'] = 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.20) Gecko/20081217 Firefox/2.0.0.20';

urlopen(req);

label["text"] = "Tweet Published!!"

label.pack({"side":"top"})

okButton["command"] = ok_act

inputBox.pack({"side":"left"})

okButton.pack()

topFrame.pack({"side":"top"})

topFrame.pack({"side":"top"});

resFrame.pack({"side":"top"})

mainFrame.pack()

root.maxsize(400,400)

root.minsize(400,400)

root.mainloop();

It’s very comfortable to work on TK. Write less, do more. A good set of widgets and a powerful language like Python as the backend… It’s simply cool 🙂

Simple Console Clock for Windows with Python

The code is self explanatory:

Python 3 Source Code:

from threading import Timer # import the Timer class
import os # import os library
import time # import time library
def main(): # define the main function
	os.system("cls") # Windows: Clear the console (Remove last printout)
	print("Time: "+time.ctime(time.time())) # Display the time
	t = Timer(1,main) # Instantiate the Timer() object with 1 sec interval -- Recursive
	t.start() # Start the timer

if __name__ == "__main__": # Check if the script is being executed from console
	main() # Start the program

from threading import Timer # import the Timer class

import os # import os library

import time # import time library

def main(): # define the main function

os.system("cls") # Windows: Clear the console (Remove last printout)

print("Time: "+time.ctime(time.time())) # Display the time

t = Timer(1,main) # Instantiate the Timer() object with 1 sec interval -- Recursive

t.start() # Start the timer

if __name__ == "__main__": # Check if the script is being executed from console

main() # Start the program

It displays a clock on Windows Command Prompt and updates it every second. It mainly demonstrates the Timer object of threading library.

PHP-GTK: App to update Twitter

2 Comments on PHP-GTK: App to update Twitter

People who have been in touch for a while might have noticed how much twitter addict I have suddenly become. Today, I wrote a php-gtk program to update my twitter status. I developed it using php-gtk2 and cURL.

I was having a lot of troubles developing it. I was using “thread safe” php while GTK is “nts (non thread safe)”. I managed a non thread safe php5 but problems raised with the cURL library. The required dependencies for cURL and mysql were not available with that package. I had to copy those specific files from another package. Again, I was getting confused as the app failed to load cURL repeatedly though I had it enabled in php.ini. Later I found out that when I copied the dependencies, I have also copied a “php-cli.ini” which was substituting the default php.ini since php was running in the CLI mode.

Finally it’s done. I am still a beginner at php-gtk. I didn’t write the program from scratch. I copy-pasted some codes from my other projects and php-gtk manual. But this program is going to be a good source of inspiration for me. I really like php-gtk. I am gonna dig a bit deeper whenever I get some time to spare.
