PySide2运行QT生成的UI

安装python

https://www.python.org/downloads/release/python-381/，选择Windows x86-64 executable installer，安装时记得将python加入环境变量

安装PySide2

命令行中运行pip install PySide2

转换文件

pyside2-uic.exe mainwindow.ui -o mainwindow.py

pyside2-rcc.exe resources.qrc -o resources.py

编写main.py

这里import的文件名要跟转换文件时一致。

import sys
import resources
from mainwindow import Ui_MainWindow
from PySide2.QtCore import (QCoreApplication, QMetaObject, QObject, QPoint,
    QRect, QSize, QUrl, Qt)
from PySide2.QtGui import (QBrush, QColor, QConicalGradient, QFont,
    QFontDatabase, QIcon, QLinearGradient, QPalette, QPainter, QPixmap,
    QRadialGradient)
from PySide2.QtWidgets import *

if __name__ == "__main__":
    app = QApplication(sys.argv)
    MainWindow = QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())
