Hildon framework provides a considerable amount of widgets. The following code has a function callback that is called every time the button generates a "clicked" event. We just change the body of button_callback function.

import gtk
import hildon

class HelloWorldApp(hildon.Program):
def __init__(self):
   hildon.Program.__init__(self)

   self.window = hildon.Window()
   self.window.connect("delete_event", self.quit)
   self.add_window(self.window)

   button = gtk.Button("Widget")
   self.window.add(button)
   button.connect("clicked", self.button_callback, self.window)
   button.show()

def quit(self, *args):
   gtk.main_quit()

def button_callback(widget, button, window):
   #PERFORM YOUR ACTION HERE
   print "Callback function"

def run(self):
   self.window.show_all()
   gtk.main()

if __name__ == "__main__":
   app = HelloWorldApp()
   app.run()

hildon.CalendarPopup

A hildon.CalendarPopup is a dialog which contains a GtkCalendar. It also contains arrow buttons for changing month/year.

def button_callback(widget, button, window):	
   dialog = hildon.CalendarPopup(window, 2008, 04, 29)
   dialog.run()
   date_tuple = dialog.get_date()
   dialog.destroy()

hildon.FontSelectionDialog

Provides the user with the possiblity to choose a different font and change its attributes, such as family, font size, font color, font weight, etc.

def button_callback(widget, button, window):
   fontDialog = hildon.FontSelectionDialog(window, "Choose a font...")
   fontDialog.set_preview_text ("Hildon Widgets")
   fontDialog.run()
   fontDialog.hide()

hildon.GetPasswordDialog

This dialog displays a text field to enter a password. The code shows a password dialog.

def button_callback(widget, button, window):
   passwordDialog = hildon.GetPasswordDialog(window, True)
   passwordDialog.set_property("password", "")
   response = passwordDialog.run()
   passwordDialog.hide() 
   if response == gtk.RESPONSE_OK:
        print passwordDialog.get_password()
