PyQt5第一个窗口

以下为通用框架：能够实现页面与逻辑分离

import sys
from QtLearning import Ui_MainWindow
from PyQt5.QtWidgets import QMainWindow, QApplication

class MyWindow(Ui_MainWindow, QMainWindow):
    def __init__(self, parent=None):
        super(MyWindow, self).__init__()
        self.setupUi(self)
        # 以下设置界面
        self.resize(400, 200)
        self.status = self.statusBar()
        self.status.showMessage("这是状态栏提示", 5000)
        self.setWindowTitle("PyQt MainWindow例子")

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