1. title Hello World!

This Python Recipe is currently being written Here is a simple GTK Example for a Hello World Program written using the Programming language called Python. Most of the code below is commented, please feel free to edit the code to match any standards. To learn more about Python, see Python.org or Python Recipes.

Code

Note: The code may look a little long, but 75% of it is just commented.

#!python
#!/usr/bin/env python
# example helloworld.py
import pygtk
pygtk.require('2.0')
import gtk
class HelloWorld:
# This is a callback function. The data arguments are ignored
# in this example. More on callbacks below.
def hello(self, widget, data=None):
print "Hello World"
def delete_event(self, widget, event, data=None):
# If you return FALSE in the "delete_event" signal handler,
# GTK will emit the "destroy" signal. Returning TRUE means
# you don't want the window to be destroyed.
# This is useful for popping up 'are you sure you want to quit?'
# type dialogs.
print "delete event occurred"
# Change FALSE to TRUE and the main window will not be destroyed
# with a "delete_event".
return False
def destroy(self, widget, data=None):
print "destroy signal occurred"
gtk.main_quit()
def <u>init</u>(self):
# create a new window
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
# When the window is given the "delete_event" signal (this is given
# by the window manager, usually by the "close" option, or on the
# titlebar), we ask it to call the delete_event () function
# as defined above. The data passed to the callback
# function is NULL and is ignored in the callback function.
self.window.connect("delete_event", self.delete_event)
# Here we connect the "destroy" event to a signal handler.  
# This event occurs when we call gtk_widget_destroy() on the window,
# or if we return FALSE in the "delete_event" callback.
self.window.connect("destroy", self.destroy)
# Sets the border width of the window.
self.window.set_border_width(10)
# Creates a new button with the label "Hello World".
self.button = gtk.Button("Hello World")
# When the button receives the "clicked" signal, it will call the
# function hello() passing it None as its argument.  The hello()
# function is defined above.
self.button.connect("clicked", self.hello, None)
# This will cause the window to be destroyed by calling
# gtk_widget_destroy(window) when "clicked".  Again, the destroy
# signal could come from here, or the window manager.
self.button.connect_object("clicked", gtk.Widget.destroy, self.window)
# This packs the button into the window (a GTK container).
self.window.add(self.button)
# The final step is to display this newly created widget.
self.button.show()
# and the window
self.window.show()
def main(self):
# All PyGTK applications must have a gtk.main(). Control ends here
# and waits for an event to occur (like a key press or mouse event).
gtk.main()
# If the program is run directly or passed as an argument to the python
# interpreter then create a HelloWorld instance and show it
if <u>name</u> == "<u>main</u>":
hello = HelloWorld()
hello.main()
