Pyqt全屏窗体拖动控件受影响

Question

网上全屏窗体拖动的教程很多，但是没有一个说，使用全屏拖动后控件会受到影响，比如使用combobox控件

#!/usr/bin/python
# -*-coding:utf-8-*-
from PyQt5.QtGui import *
from PyQt5.Qt import *
from PyQt5.QtCore import *


class AboutUsDialog(QDialog):

    def __init__(self, parent=None):
        super(AboutUsDialog, self).__init__(parent)
        self.setWindowFlags(Qt.FramelessWindowHint | Qt.Dialog)
        self.setGeometry(120, 0, 120, 80)
        self.co = QComboBox(self)
        self.co.addItems(["test21","testf"])

    def mousePressEvent(self, event):
        if event.button() == Qt.LeftButton:
            self.dragPosition = event.globalPos() - self.frameGeometry().topLeft()
            QApplication.postEvent(self, QEvent(174))
            event.accept()

    def mouseMoveEvent(self, event):
        if event.buttons() == Qt.LeftButton:
            self.move(event.globalPos() - self.dragPosition)
            event.accept()


if __name__ == '__main__':
    import sys

    app = QApplication(sys.argv)
    aboutus = AboutUsDialog()
    aboutus.show()
    sys.exit(app.exec_())

下面是一个窗口拖动的例子，加了comboboxr控件后，运行当点击combobox会闪退或者窗口会闪到别的位置去,这种不好解决
