为窗口设置图标

import sys
from PyQt5.QtGui import QIcon
from PyQt5.QtWidgets import QWidget, QApplication

#  创建一个Icon类，继承Qwidget类
class Icon(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()


    # 初始化窗口
    def initUI(self):
        self.setGeometry(300, 300, 250, 150)
        self.setWindowTitle(\'程序图标\')
        self.setWindowIcon(QIcon(\'1.ico\'))

if __name__ == \'__main__\':
    app = QApplication(sys.argv)
    icon = Icon()
    icon.show()
    sys.exit(app.exec())
