Qt窗口继承

写一个自定义类继承QWidget

  1. from PyQt5.QtWidgets import *
  2. from PyQt5.QtCore import *
  3. from PyQt5.QtGui import *
  4. import sys
  7. class MyWindow(QWidget):
  9.     def __init__(self, title):
  10.         super().__init__()
  11.         self.setWindowTitle(title)
  14. if __name__ == '__main__':
  15.     app = QApplication(sys.argv)
  17.     window = MyWindow("窗口标题")
  18.     window.show()
  20.     sys.exit(app.exec_())

通过继承QWidget来实现窗体
在构造中，必须调用super函数，否则将出行错误

初始化ui

  1. from PyQt5.QtWidgets import *
  2. from PyQt5.QtCore import *
  3. from PyQt5.QtGui import *
  4. import sys
  7. class MyWindow(QWidget):
  9.     def __init__(self, title):
  10.         super().__init__()
  11.         self.setWindowTitle(title)
  12.         self.init_ui()
  14.     def init_ui(self):
  15.         layout = QHBoxLayout()
  16.         # ---------------------------------
  18.         # 在这里初始化界面内容
  20.         # ---------------------------------
  21.         self.setLayout(layout)
  24. if __name__ == '__main__':
  25.     app = QApplication(sys.argv)
  27.     window = MyWindow("窗口标题")
  28.     window.show()
  30.     sys.exit(app.exec_())
