• 視窗縮放時會觸發 resizeEvent ，而視窗關閉時會觸發 closeEvent 因此有物件要在視窗縮放或關閉時操作就寫入這些function裡

from PyQt5 import QtWidgets, QtGui, QtCoreclass MyWindow(QtWidgets.QMainWindow):
 def __init__(self):
  super().__init__()
  self.setupUi()
  self.show()def setupUi(self):
  self.resize(400, 400)def resizeEvent(self, event):
  print('resize')
  width, height = event.size().width(), event.size().height()
  print(event.size())
  print(width, height)def closeEvent(self, event):
  print('window close')if __name__ == '__main__':
 import sys
 app = QtWidgets.QApplication(sys.argv)
 window = MyWindow()
 sys.exit(app.exec_())
