Hi to all,
A long ago Raji akka teached pygtk to us, also i learned pygtk with eager at the time. But after that i didn’t worked it out regularly, fortunately i had to do some simple task in pygtk, I started it from scratch finally i did one Hello World program and Simple currency converter. May be these programs are simple, but it shows i too know pygtk 😉
1. Hello World program
#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk
class HelloWorld:
def hello(self, widget, data=None):
print "Hello World"
def delete_event(self, widget, event, data=None):
print "delete event occurred"
return False
def destroy(self, widget, data=None):
print "Completely quit"
gtk.main_quit()
def __init__(self):
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.connect("delete_event", self.delete_event)
self.window.connect("destroy", self.destroy)
self.window.set_border_width(50)
self.hobox = gtk.HBox(False, 0)
self.window.add(self.hobox)
self.b = gtk.Button("Hello World")
self.b.connect("clicked", self.hello)
self.hobox.pack_start(self.b, True, False, 0)
self.b.show()
self.a=gtk.Button(" Exit ")
self.a.connect("clicked", self.destroy)
self.hobox.pack_start(self.a, True, False, 0)
self.a.show()
self.hobox.show()
self.window.show()
def main(self):
gtk.main()
if __name__ == "__main__":
hello = HelloWorld()
hello.main()
Here is the screen shot:
To get the output…………?
* Copy and paste the code in text editor.
* save the filename with .py extenstion
* run the file with the following command in terminal python filename.py
* You will get a window like above 🙂
2. Simple Currency Converter:
import pygtk
pygtk.require('2.0')
import gtk
class Conversion:
def convert(self,widget):
self.t1=self.text1.get_text()
self.val=int(self.t1)
self.vali=self.val*44.75
self.text2.set_text(str(self.vali))
self.vale=self.val*0.68
self.text3.set_text(str(self.vale))
def delete_event(self, widget, event, data=None):
print "delete event occurred"
return False
def destroy(self, widget, data=None):
print "Completely quit"
gtk.main_quit()
def __init__(self):
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.connect("delete_event", self.delete_event)
self.window.connect("destroy", self.destroy)
self.window.set_border_width(60)
table=gtk.Table(4, 2, True)
self.window.add(table)
self.label1=gtk.Label("Enter USD Amount: ")
table.attach(self.label1, 0, 1, 0, 1)
self.label1.show()
self.text1=gtk.Entry(0)
table.attach(self.text1, 1,2,0,1)
self.text1.show()
self.label2=gtk.Label("Indian Value Is (INR): ")
table.attach(self.label2, 0,1,1,2)
self.label2.show()
self.text2=gtk.Entry(0)
table.attach(self.text2, 1,2,1,2)
self.text2.show()
self.label3=gtk.Label("Euro Value Is (EUR): ")
table.attach(self.label3, 0,1,2,3)
self.label3.show()
self.text3=gtk.Entry(0)
table.attach(self.text3, 1,2,2,3)
self.text3.show()
self.but1=gtk.Button("Convert")
self.but1.connect("clicked",self.convert)
table.attach(self.but1,0,1,3,4)
self.but1.show()
self.but2=gtk.Button("Quit")
self.but2.connect("clicked",self.destroy)
table.attach(self.but2,1,2,3,4)
self.but2.show()
table.show()
self.window.show()
def main(self):
gtk.main()
if __name__ == "__main__":
conversion = Conversion()
conversion.main()

As mentioned above do it here also.
* Copy and paste the code in text editor.
* save the filename with .py extenstion
* run the file with the following command in terminal python filename.py
* You will get a window like above 🙂
It will help to beginner to learn pygtk.
Thank You
