QT

1、将UI文件转化为PY文件

Python - m pyqt5.uic.pyuic demo.ui - o demo.py

方法二：

pyuic.exe demo.ui -o demo.py

C:\Users\lion\PycharmProjects\pythonProject1\venv\Scripts\pyuic5.exe

# 需要安装pyuic

2、调用UI.py

import sys
import FdUI
from PyQt5.Qt import *
if __name__ =='__main__':
    app = QApplication(sys.argv)
    #声明主窗口
    mainwindow = QMainWindow()
    #初始化UI类实例
    ui = FdUI.Ui_MainWindow()
    #绑定主窗口与UI
    ui.setupUi(mainwindow)
    mainwindow.show()
    sys.exit(app.exec_())
3、信号与槽
