# ApplicationWindow

La ventana de GtkApplication más sencilla que puede soportar .

# Código usado para generar este ejemplo

from gi.repository import Gtk import sys

# a Gtk ApplicationWindow

class MyWindow(Gtk.ApplicationWindow): # constructor: the title is "Welcome to GNOME" and the window belongs # to the application app

def __init__(self, app): Gtk.Window.__init__(self, title="Welcome to GNOME", application=app)

class MyApplication(Gtk.Application): # constructor of the Gtk Application

def __init__(self): Gtk.Application.__init__(self)

# create and activate a MyWindow, with self (the MyApplication) as # application the window belongs to. # Note that the function in C activate() becomes do_activate() in Python def do_activate(self): win = MyWindow(self) # show the window and all its content # this line could go in the constructor of MyWindow as well win.show_all()

# start up the application # Note that the function in C startup() becomes do_startup() in Python def do_startup(self): Gtk.Application.do_startup(self)

# create and run the application, exit with the value returned by # running the program app = MyApplication() exit_status = app.run(sys.argv) sys.exit(exit_status)

# Métodos útiles para un widget «Gtk.ApplicationWindow»

`set_default_size(200, 100)` establece el tamaño predeterminado de la ventana a una anchura de `200` y una altura de `100`; si en lugar de un número positivo le pasa `-1` tendrá el tamaño predeterminado.

`set_position(Gtk.WindowPosition.CENTER)` centra la ventana. Otras opciones son `Gtk.WindowPosition.NONE, Gtk.WindowPosition.MOUSE, Gtk.WindowPosition.CENTER_ALWAYS, Gtk.WindowPosition.CENTER_ON_PARENT`.
