解决pyside2的uic转换C++代码的问题（ 2021-05-27）

解决pyside2的uic转换C++代码的问题
不能直接用pyside2包目录下的uic.exe文件。可能是电脑上面安装了C++的Qt，所以Uic会将ui文件装换成C++源代码，而不是Python源代码。
为此，pyside2提供了专门的装换插件，pyside2-uic，该插件能将ui文件装换为Python代码。
在pycharm中配置如下：
下面是参数

$FileName$ -o $FileNameWithoutExtension$.py

from PySide2.QtCore import *
from PySide2.QtGui import *

        self.centralwidget = QWidget(MainWindow)
        self.centralwidget.setObjectName(u"centralwidget")

        self.pushButton.setObjectName(u"pushButton")
        self.pushButton.setGeometry(QRect(160, 160, 101, 31))
        self.pushButton_2 = QPushButton(self.centralwidget)
