Python 如何检查PyQt6中的MouseButtonPress事件？

在PyQt5中，我们可以使用QEvent类验证事件发生，例如QEvent.MouseButtonPress。在PyQt6中，该语句不再有效。我检查了

PyQt6.QtCore.QEvent

和

PyQt6.QtGui.QMouseEvent

类的成员，似乎无法找到包含MouseButtonPress事件值的正确枚举类

PyQt5示例我正在尝试转换为PyQt6

PyQt6枚举使用python枚举的主要更改之一，因此您必须使用枚举名称作为中介，在您的情况下，MouseButtonPress属于类型enum，RightButton属于MouseButtons，因此您必须将其更改为：

def eventFilter(self, QObject, event):
    if event.type() == QEvent.Type.MouseButtonPress:
        if event.button() == Qt.MouseButtons.RightButton:
            print("Right button clicked")

    return True

def eventFilter（self、QObject、event）：
如果event.type（）==QEvent.type.mousebutton按下：
如果event.button（）==Qt.MouseButtons.RightButton：
打印（“单击右键”）
return True

如果我打印QEvent的成员，则所有这些都可用。”“接受”、“克隆”、“忽略”、“isAccepted”、“isInputEvent”、“isPointerEvent”、“isSinglePointEvent”PS：在post.Oh中添加了其他详细信息。真不敢相信我错过了。非常感谢你。
