Best practise in the implementation of QTabWidget and corner widget

[NonNT]

class MyWidget(QWidget):

    def __init__(self, parent=None):
        super(MyWidget, self).__init__(parent)

        self.buttonInfo = QPushButton(self)
        self.buttonInfo.setIcon(QIcon('help-about.svg'))
        self.buttonInfo.setFlat(True)
        self.buttonInfo.clicked.connect(self.onButtonInfoClicked)

        self.tabs = QTabWidget()
        self.tabs.setDocumentMode(True)
        self.tabs.setMovable(True)
        self.tabs.setTabsClosable(True)
        self.tabs.setCornerWidget(self.buttonInfo)
        self.tabs.tabCloseRequested.connect(self.onButtonTabCloseClicked)

        layout = QVBoxLayout()
        layout.addWidget(self.tabs)

        self.setLayout(layout)


    ...
    def onButtonInfoClicked(self):

        title = QLabel()

        content = QWidget()

        button = QPushButton('Close')
        button.setShortcut(QKeySequence.Cancel)
        button.clicked.connect(self.onButtonInfoCloseClicked)

        layout = QVBoxLayout()
        layout.addWidget(title)
        layout.addWidget(content)
        layout.addWidget(button)

        self.page = QWidget()
        self.page.setLayout(layout)

        self.layout().removeWidget(self.tabs)
        self.tabs.setParent(None)
        self.layout().addWidget(self.page)


    def onButtonInfoCloseClicked(self):

        self.layout().removeWidget(self.page)
        self.page.setParent(None)
        self.layout().addWidget(self.tabs)

1. What is the best practise in the implementation of QTabWidget and corner widget?
   It works, but is it the best solution?

2. And how can I implement the shortcut without button to close the page?

Thanks

#2 is fixed:

shortcut = QShortcut(QKeySequence.Cancel, self.page)
shortcut.activated.connect(self.onButtonInfoCloseClicked)

@NonNT said in Best practise in the implementation of QTabWidget and corner widget:

corner widget

What do you mean by this?

[NonNT]

@jsulm
A widget shown in the corner of the tab widget.
https://doc.qt.io/qt-5/qtabwidget.html#cornerWidget

To display the page instead of the tabs widget, I'm just doing the following:

1. remove tabs widget from the layout
2. unparent tabs widget
3. add page widget to the layout

and vice versa to display the tabs widget again.

But it is the best solution?
