检测 QWebEngineView 上的鼠标点击

Question

如何检测 QWebEngineView 小部件中的鼠标单击？

我尝试过这个但不起作用：

class MyWin(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        QtWidgets.QWidget.__init__(self, parent)

        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.ui.view.installEventFilter(self)

    def eventFilter(self, obj, event):
        if event.type() == event.MouseButtonPress:
             print ("Widget click")
        return super(QtWidgets.QMainWindow, self).eventFilter(obj, event)

假设视图是 QWebEngineView 对象，并且您想要跟踪其鼠标事件，那么您应该使用 focusProxy，它是处理这些类型事件的内部小部件。另一方面，您必须正确应用继承。

class MyWin(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super(MyWin, self).__init__(parent)

        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

        self.ui.view.focusProxy().installEventFilter(self)

    def eventFilter(self, obj, event):
        if obj is self.ui.view.focusProxy() and event.type() == event.MouseButtonPress:
            print("Widget click")
        return super(MyWin, self).eventFilter(obj, event)
