[Couleur] Appliquer une couleur de fond à un item

**mathieu_r** · 16/03/2009, 17h51

Bonjour,

je suis en train de développer une application dans laquelle on choisit une couleur.

J'aimerais colorier le bouton qui ouvre la fenêtre de sélection de couleur avec la couleur choisie

J'ai essayé d'effectuer cela en m'inspirant d'un tuto trouvé sur le net:
http://web.univ-pau.fr/~puiseux/ense...leur%20|region

Voici la portion de mon code qui devrait permettre cela:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

 def color_dialog(self):
        couleur = QtGui.QColorDialog.getColor()
        palette=QtGui.QPalette() 
        palette.setColor(QtGui.QPalette.Button, couleur)
        self.ui.bt_applycolor.setPalette(palette)
 
        self.ui.txt_color.setText(couleur.name())

Mais je n'arrive pas à faire fonctionner mon programme...

Comment le faire?
Plus simplement, comment, par exemple, appliquer une couleur de fond à un label?

Pour info, voici mon code en entier:

    def selectionListe(self,item):
        self.ui.txt_color.setText(item.text(1))
 
if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = MyForm()
    myapp.show()
    sys.exit(app.exec_())

Je vous remercie par avance,

Peux-tu ajouter le code Ui_dialog.py et aussi éventuellement sa version ui, ie celle utilisée par Qt Designer (c'est un fichier de type XML) ?

Bonjour,
Avec le style css :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2

 def color_dialog(self):
        couleur = QtGui.QColorDialog.getColor().name()
        self.ui.bt_applycolor.setStyleSheet("QPushButton {backGround:%s}" %(couleur))
