How to make QMainWindow close by button on QDockWidget?

Question

Python

Good day. It is necessary to add the closing of the main window by the QPushButton button. I can't find any information on how to do this. Here is part of my code

class MainWindow(QMainWindow):
    def __init__(self, *args, **kwargs):
        super(MainWindow, self).__init__(*args, **kwargs)

        self.browser = QWebEngineView()
        self.browser.setUrl(QUrl("http://yandex.ru"))

        self.browser.urlChanged.connect(self.update_urlbar)
        self.browser.loadFinished.connect(self.update_title)
        self.setCentralWidget(self.browser)

        self.status = QStatusBar()
        self.setStatusBar(self.status)

## QDockWidget ##
        self.docked = QDockWidget("Виджет", self)
        self.addDockWidget(Qt.LeftDockWidgetArea, self.docked)
        self.dockedWidget = QWidget(self)
        self.docked.setWidget(self.dockedWidget)
        self.dockedWidget.setLayout(QVBoxLayout())
        self.dockedWidget.layout().addWidget(QPushButton('Завершить работу'))

The button is created on the panel, but how can I add it so that the window closes on click? I turned off the standard cross, this option is needed. Help who can)

Answer 1

self.closeBtn = QPushButton(self.tr('Close'))
self.closeBtn.clicked.connect(self.close)
self.dockedWidget.layout().addWidget(self.closeBtn)

Here is the documentation:
https://doc.qt.io/qt-5/qwidget.html#close

Well, there are also docks on pyside itself. Although, you can just look at Qt. pyside is just bindings after all.
