Convert the ui file of Qt Designer to the .py file used by PySide2

20201206 revision: in the 5.15.2 version of Pyside2, the process of generating py files from ui, the command changed from "uic" to "pyside2-uic"

The ui file designed by Qt Designer is an xml file, which can be converted into a standard .py file through pyside-uic. The ui created through QtDesigner is as shown in the figure:

Let’s cut to the chase:

1: First make sure to add pyside2-uic.exe to the environment variable Path. According to my Python, PySide2 installation path. The settings are as follows:

2: Use the QtDesigner tool in PySide2 to create specific ui files. The QtDesigner path is as follows:

3: Use the command to generate the corresponding .py file from the created ui file. First enter the location of the ui file from the cmd of the system, and then enter the command:

pyside2-uic ****.ui -o ****.py

Perform file conversion. Note: "pyside2-uic" changed to "uic" in PySide2 5.15.2 version, but the command uic in cmd is invalid, only "pyside2-uic" command can be used

Operating normally. The generated py file code is as follows:

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'untitled.ui',
# licensing of 'untitled.ui' applies.

from PySide2 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.widget = QtWidgets.QWidget(self.centralwidget)
        self.widget.setGeometry(QtCore.QRect(0, 0, 801, 571))
        self.widget.setObjectName("widget")
        self.verticalLayout = QtWidgets.QVBoxLayout(self.widget)
        self.verticalLayout.setContentsMargins(0, 0, 0, 0)
        self.verticalLayout.setObjectName("verticalLayout")
        self.horizontalLayout_2 = QtWidgets.QHBoxLayout()
        self.horizontalLayout_2.setObjectName("horizontalLayout_2")
        self.horizontalLayout = QtWidgets.QHBoxLayout()
        self.horizontalLayout.setObjectName("horizontalLayout")
        self.pushButton = QtWidgets.QPushButton(self.widget)
        self.pushButton.setObjectName("pushButton")
        self.horizontalLayout.addWidget(self.pushButton)
        self.pushButton_2 = QtWidgets.QPushButton(self.widget)
        self.pushButton_2.setObjectName("pushButton_2")
        self.horizontalLayout.addWidget(self.pushButton_2)
        self.horizontalLayout_2.addLayout(self.horizontalLayout)
        self.label = QtWidgets.QLabel(self.widget)
        self.label.setObjectName("label")
        self.horizontalLayout_2.addWidget(self.label)
        self.verticalLayout.addLayout(self.horizontalLayout_2)
        self.plainTextEdit = QtWidgets.QPlainTextEdit(self.widget)
        self.plainTextEdit.setObjectName("plainTextEdit")
        self.verticalLayout.addWidget(self.plainTextEdit)
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 23))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(QtWidgets.QApplication.translate("MainWindow", "MainWindow", None, -1))
        self.pushButton.setText(QtWidgets.QApplication.translate("MainWindow", "PushButton", None, -1))
        self.pushButton_2.setText(QtWidgets.QApplication.translate("MainWindow", "PushButton", None, -1))
        self.label.setText(QtWidgets.QApplication.translate("MainWindow", "TextLabel", None, -1))

4: Then put the generated .py file under the specific path and load it through py. The specific example code is as follows:

import sys
from PySide2.QtWidgets import QApplication
from PySide2.QtWidgets import QMainWindow

from ch06.Untitled import Ui_MainWindow


class LoginForm(QMainWindow):
    def __init__(self, parent=None):
        QMainWindow.__init__(self, parent)

        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)


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

Run, the result is as shown below:
