重点是 from PyQt5.QtGui import QIcon
QIcon接受的参数:
image.png
一般给个本地文件路径就行了.
代码:
# coding='utf-8'
import sys
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtGui import QIcon
class Gui(QWidget):
def __init__(self):
super().__init__()
def start(self):
self.setGeometry(250, 250, 800, 600)
self.setWindowTitle('第二个Icon')
self.setWindowIcon(QIcon('./图片素材/app图标/5.png'))
self.show()
main = QApplication(sys.argv)
gui = Gui()
gui.start()
sys.exit(main.exec_())
image.png
