bonjour;

j'essaye de créer pour test une fenêtre MainWindow que j'ai subdivise en deux blocs (bloc_right et bloc_left):

bloc_left est un widgte QFrame vertical qui contient deux boutons QPushbutton : bouton1  et bouton2

bloc_left est un widget QFrame qui doit normalement contenir deux widgtes QFrame "frame1"  et " frame2"

je souhaite que lorque :

* je clique sur le bouton , c'est la frame1 qui s'affiche avec son contenu.

* si je clique sur le bouton2, la frame1 disparait et c'est la fram2 qui s’affiche avec son contenu

j'ai utiliser deux fichiers (index.py) et ( main.ui)

index.py :

# PyQT5 :
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.uic import loadUiType

# import os :
import os
from os import path
import sys

# import UI_File :
FORM_CLASS,_ = loadUiType(path.join(path.dirname(__file__),"main.ui"))

#Initiate UI_File :
class MainApp(QMainWindow,FORM_CLASS) :
    def __init__(self,parent=None) :
        super(MainApp,self).__init__(parent)
        QMainWindow.__init__(self)
        self.setupUi(self)
        self.mainUi()
        self.pushButton.clicked.connect(self.bouton1)
        self.pushButton_2.clicked.connect(self.bouton2)
    
    def mainUi(self):
        self.setWindowTitle("window for test")

    def bouton1(self)   :
        # hide the frame and its contents
        self.frame_3.hide()
        # show the frame and its contents
        self.frame_4.show() 

    def bouton2(self)   :
        # hide the frame and its contents
        self.frame_4.hide()
        # show the frame and its contents
        self.frame_3.show() 

def main():
    app=QApplication(sys.argv)
    window=MainApp()
    window.show()
    app.exec_()# infinite loop

if __name__=='__main__' :
    main()

main.ui :(cree avec Qtdesigner)
