PyQt中为窗口设置logo

python

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


class iconform(QMainWindow):
    def __init__(self):
        super(iconform, self).__init__()
        self.setupUI()

    def setupUI(self):
        self.resize(1182, 563)
        self.setWindowTitle('Create Anime characters with DCGan!')
        self.setWindowIcon(QIcon('dataset/favicon.ico'))


if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainwindow = iconform()
    mainwindow.show()
    sys.exit(app.exec_())

科研实践虽然难，但每天自己能进步，有所收获，定能完成！

补(在designer设计的代码中修改)同样可以实现效果
