如何在不实际按下鼠标的情况下在QML/Pyside2 2中创建鼠标按下或单击事件

from PySide2.QtCore import Qt, QEvent
from PySide2.QtGui import QMouseEvent
from PySide2.QtWidgets import QApplication, QWidget

class MyWidget(QWidget):
    def __init__(self):
        super().__init__()

    def mousePressEvent(self, event):
        # 在鼠标按下时触发的事件处理函数
        print("鼠标按下")

    def mouseReleaseEvent(self, event):
        # 在鼠标释放时触发的事件处理函数
        print("鼠标释放")

    def mouseDoubleClickEvent(self, event):
        # 在鼠标双击时触发的事件处理函数
        print("鼠标双击")

app = QApplication([])
widget = MyWidget()
widget.installEventFilter(widget)
widget.show()
app.exec_()

import PySide2.QtCore 2.15

MouseArea {
    id: mouseArea
    anchors.fill: parent
    onPressed: {
        widget.mousePressEvent()
    }
    onReleased: {
        widget.mouseReleaseEvent()
    }
    onDoubleClicked: {
        widget.mouseDoubleClickEvent()
    }
}
