import sys
from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow, QVBoxLayout, QWidget
class HelloWorldApp(QMainWindow):
pass
if __name__ == '__main__':
app = QApplication(sys.argv)
window = HelloWorldApp()
window.show()
sys.exit(app.exec_())
另一個測試
Set some variables
import sys
from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow, QVBoxLayout, QWidget
class HelloWorldApp(QMainWindow):
