[FIXED] Is there an elegant way to delete a widget in QScrollArea in PyQt?

Issue

I am learning PyQt5 recently and have problems when I want to delete a widget in QScrollArea. Is there an elegant way to visit the element in QScrollArea and delete it when the "delete" button in that element is clicked? Thank you for any help!

class MyWidget(QWidget):
    def __init__(self, id):
        super().__init__()
        self.layout = QHBoxLayout()
        self.layout.addWidget(QPlainTextEdit(id))
        self.layout.addWidget(QPushButton('Delete'))
        self.setLayout(self.layout)

        # connect options
        connect_options()
    

    def connect_options(self):
        pass


class MyList(QScrollArea):
    def __init__(self):
        super().__init__()
        self.layout = QVBoxLayout()
        self.widget = QWidget()
        for x in range(10):
            self.layout.addWidget(MyWidget(str(x)))
        self.widget.setLayout(self.layout)

        self.setMinimumSize(1024, 500)
        self.setWidget(self.widget)

Solution

First I would suggest you look into QListWidget, It will provide you various functions to handle situations like this.

for your problem, you will need to delete the widget from its parent layout & then delete it from the GUI

class MyWidget(QWidget):
    def __init__(self, id):
       super().__init__()
       self.layout = QHBoxLayout()
       self.layout.addWidget(QPlainTextEdit(id))
       del_btn = QPushButton('Delete') 
       del_btn.clicked.connect(self._delete) # connect the click event to your delete function
       self.layout.addWidget(del_btn)
       self.setLayout(self.layout)

       # connect options
       self.connect_options()


    def connect_options(self):
       pass

    def _delete(self):
       # here you will delete your widget
       parent_layout = self.parent().layout()
       parent_layout.removeWidget(self) # remove the widget from its parent layout
       self.deleteLater() # lets Qt knows it needs to delete this widget from the GUI
       del self
