Python: Using Output From Method's Class Inside Another Class

I am trying to develop my first app with PyQt5 (a memory game). I have created two classes: MainApplication, which inherits from QMainWindow, and GridWidget, which inherits from QW

Solution 1:

I think it will be simpler if you keep everything in one class. You should make each child widget an attribute of the class, so you can access them later using self within the methods of the class. All the program logic will go in the methods - so it's just a matter of calling methods in response to signals and events.

Here is what the class should look like:

classMainApplication(QMainWindow):
    def__init__(self):
        super().__init__()
        self.initUI()

    definitUI(self):
        self.statusBar()

        openFile = QAction('Open', self)
        openFile.setStatusTip('Search image folder')
        openFile.triggered.connect(self.showDialog)

        menubar = self.menuBar()
        self.fileMenu = menubar.addMenu('&File')
        self.fileMenu.addAction(openFile)

        self.gridWidget = QWidget(self)
        self.gridLayout = QGridLayout(self.gridWidget)
        self.setCentralWidget(self.gridWidget)

        self.setGeometry(300, 300, 350, 300)
        self.setWindowTitle('Memory Game!')
        self.show()

    defpopulateGrid(self, images):
        names = images * 2
        positions = [(i,j) for i inrange(int(len(names)/2)) for j inrange(int(len(names)/2))]
        for position, name inzip(positions, names):
            if name == '':
                continue
            button = QPushButton(name)
            self.gridLayout.addWidget(button, *position)

    defshowDialog(self):
        folder = str(QFileDialog.getExistingDirectory(self, "Select Directory",
            '/home', QFileDialog.ShowDirsOnly))

        images = glob.glob(os.path.join(folder, '*.jpg'))

        if images:
            self.populateGrid(images)
