Comment afficher un gif animé dans l'application que je suis en train de développer ?

Puisque vous avez ajouté GTK à votre question, exemple et documentation est disponible dans le didacticiel PyGTK 2.0 sur le site Web de Chapitre 9. Widgets divers .

A exemple de code en utilisant .gif pour les boutons :

#!/usr/bin/env python

# example images.py

import pygtk
pygtk.require('2.0')
import gtk

class ImagesExample:
    # when invoked (via signal delete_event), terminates the application.
    def close_application(self, widget, event, data=None):
        gtk.main_quit()
        return False

    # is invoked when the button is clicked.  It just prints a message.
    def button_clicked(self, widget, data=None):
        print "button %s clicked" % data

    def __init__(self):
        # create the main window, and attach delete_event signal to terminating
        # the application
        window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        window.connect("delete_event", self.close_application)
        window.set_border_width(10)
        window.show()

        # a horizontal box to hold the buttons
        hbox = gtk.HBox()
        hbox.show()
        window.add(hbox)

        pixbufanim = gtk.gdk.PixbufAnimation("goalie.gif")
        image = gtk.Image()
        image.set_from_animation(pixbufanim)
        image.show()
        # a button to contain the image widget
        button = gtk.Button()
        button.add(image)
        button.show()
        hbox.pack_start(button)
        button.connect("clicked", self.button_clicked, "1")

        image = gtk.Image()
        image.set_from_file("soccerball.gif")
        image.show()
        # a button to contain the image widget
        button = gtk.Button()
        button.add(image)
        button.show()
        hbox.pack_start(button)
        button.connect("clicked", self.button_clicked, "2")

def main():
    gtk.main()
    return 0

if __name__ == "__main__":
    ImagesExample()
    main()

RÉPONSE ORIGINALE

Vous pouvez utiliser PyQt avec le QMovie() widget pour jouer un gif animé. Ci-dessous un exemple que j'ai trouvé plus tôt.

Exemple de Python GUI Programming | DaniWeb site web :

# use PyQt's QMovie() widget to play an animated gif
# tested with PyQt4.4 and Python 2.5
# also tetsed with PyQt4.5 and Python 3.0
# vegaseat

import sys
# expect minimal namespace conflicts
from PyQt4.QtCore import *
from PyQt4.QtGui import * 

class MoviePlayer(QWidget):
    def __init__(self, parent=None): 

    QWidget.__init__(self, parent)
    # setGeometry(x_pos, y_pos, width, height)
    self.setGeometry(200, 200, 400, 300)
    self.setWindowTitle("QMovie to show animated gif")

    # set up the movie screen on a label
    self.movie_screen = QLabel()
    # expand and center the label
    self.movie_screen.setSizePolicy(QSizePolicy.Expanding,
    QSizePolicy.Expanding)
    self.movie_screen.setAlignment(Qt.AlignCenter) 

    main_layout = QVBoxLayout()
    main_layout.addWidget(self.movie_screen)
    self.setLayout(main_layout)

    # use an animated gif file you have in the working folder
    # or give the full file path
    movie = QMovie("AG_Dog.gif", QByteArray(), self)
    movie.setCacheMode(QMovie.CacheAll)
    movie.setSpeed(100)
    self.movie_screen.setMovie(movie)
    movie.start() 

app = QApplication(sys.argv)
player = MoviePlayer()
player.show()
sys.exit(app.exec_())
