Salut à tous.Je débute en Python et je viens de me mettre à PyQT.

Je suis pour le moment entrain de créer une interface graphique afin de faire un Jeu du Pendu. Quand QT Creator, j'ai placer 26 pushButtons qui correspondent à chaque lettres de l'alphabet.

Je cherche maintenant, que lorsque quelqu'un clique sur un bouton, le Label du bouton soit affiché dans ma fenêtre. (afin de faire des test)

Le problème, c'est que je ne sais pas comment procéder. Je sais comment faire pour un bouton précis, mais comment rendre la méthode "universelle" pour les 26 boutons présents ? Est-ce possible, ou faut-t-il copier 26 fois la même ligne en changeant le nom du bouton ?

		super(Window, self).__init__(parent)
		self.initGui()
		self.setWindowTitle(str(title))

	def getPushButtonText(self):
		print(self.ui.pushButton.text()) # Print letter A

	def initGui(self):
		self.ui = Ui_widget()
		self.ui.setupUi(self)

		self.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), self.getPushButtonText) #Button 1 => Letter A

if __name__ == "__main__":
	app = Gui.QApplication(sys.argv)
	win = Window('Jeu du Pendu')
	win.show()
	sys.exit(app.exec_())

Bonjour,

Tu peux utiliser des listes pour stocker tes boutons et les informations les concernant :

# buttonProperties : [QPushButton, x, y, name, text]
buttonProperties = [[None, 10, 10, "pushButton_1", "A"],
                    [None, 30, 10, "pushButton_7", "B"]] # à completer bien sur
pushbutton = []
for elem in buttonproperties:
    elem[0] = QtGui.QPushButton(self.clavier)
    elem[0].setGeometry(QtCore.QRect(elem[1], elem[2], 31, 31))
    elem[0].setObjectName(_fromUtf8(elem[3]))
    elem[0].setText(_translate("widget", elem[5], None))

for i in range(len(buttonProperties)):
    widget.setTabOrder(buttonProperties[i][0], buttonProperties[i+1][0])

Il faut compléter la liste buttonProperties avec les informations concernant tes boutons dans l'ordre dans lequel tu veux les afficher (la deuxième boucle for les ordonne en suivant l'ordre de la liste).

Pour connecter les boutons, tu peux dériver la classe QPushButton pour rajouter un signal personnalisé : clickedText(text). ce signal sera émis à chaque fois que tu cliqueras sur le bouton et il passera en argument le texte du bouton. Il ne te reste plus qu'à le connecter avec un slot personnalisé qui récupèrera cet argument pour l'afficher :

class DerivedButton (QPushButton):
    def __init__(self):
        QPushButton.__init__(self)
        self.connect(self, SIGNAL("clicked()"), sendText)
    
    def sendText(self):
        self.emit(SIGNAL("clickedText(PyQt_PyObject)"), self.text())

class Window(Gui.QWidget):
    def __init__(self):
        # ...
    
    def initGui(self):
        # ...
        
        for derivedButton in self.buttonproperties:
            self.connect(derivedButton, SIGNAL("clicked(PyQt_PyObject)"), self.afficheButtonText)
    
    def afficheButtonText(self, text):
        print text
        

Je n'ai pas testé le code ci-dessus, mais en tout cas c'est l'idée.

EDIT : il existe en fait une méthode plus simple. Il est inutile de créer une classe dérivée, on utilise la méthode sender().

class Window(Gui.QWidget):
    def __init__(self):
        # ...
    
    def initGui(self):
        # ...
        
        for PushButton in self.buttonproperties:
            PushButton[0].clicked.connect(self.afficheButtonText)
    
    def afficheButtonText(self):
        sender = self.sender()
        print sender.text()

Parfait! C'est pile poil ce qu'il me faut. Je te remercie
