python之当你发现QTimer不能用时的解决方法
如下所示:
# -*- coding: utf-8 -*- import numpy as np from PyQt5.QtCore import QTimer, QObject from PyQt5.QtWidgets import QWidget, QApplication import sys import time class my_timer(QWidget): def __init__(self): super(my_timer, self).__init__() self.my_t = QTimer(self) # self.my_t.setInterval(1000) self.my_t.start(1000) self.my_t.timeout.connect(self.my_function) def my_function(self): for i in range(10): print('_(%s)' % str(i)) time.sleep(0.5) if __name__ == '__main__': app = QApplication(sys.argv) w = my_timer() w.show() sys.exit(app.exec_())
当你发现你用QTimer的时候没有效果时,请把QTimer赋予到界面里面吧,当你把QTimer写入界面的时候,就会发现QTimer能用了。
