如下所示:
import sys from PyQt5 import QtGui, QtCore, QtWidgets from PyQt5.QtWidgets import * from PyQt5.QtCore import * from PyQt5.QtGui import * class showTime(QDialog): def __init__(self): super(showTime, self).__init__() self.resize(500, 400) self.setWindowTitle("label显示时间") self.label = QLabel(self) self.label.setFixedWidth(200) self.label.move(90, 80) self.label.setStyleSheet("QLabel{background:white;}" "QLabel{color:rgb(300,300,300,120);font-size:10px;font-weight:bold;font-family:宋体;}" ) # 动态显示时间在label上 timer = QTimer(self) timer.timeout.connect(self.showtime) timer.start() def showtime(self): datetime = QDateTime.currentDateTime() text = datetime.toString() self.label.setText(" "+ text) if __name__ == '__main__': app = QtWidgets.QApplication(sys.argv) my = showTime() my.show() sys.exit(app.exec_())
