将Qt Designer的ui文件转换为PySide2使用的.py文件

自闭症网瘾萝莉.ら 提交于 2020-10-25 23:03:08

Qt Designer 设计的ui文件,就是一个xml文件,通过pyside-uic可以转换成标准的.py文件 。通过QtDesigner创建的ui如图:

我们切入正题:

1:首先要保证将pyside2-uic.exe加到环境变量Path中。根据我的Python,PySide2安装路径。设置具体如下图:

                      

2:使用PySide2中的QtDesigner工具创建具体的ui文件。QtDesigner路径如下:

3:将创建的ui文件使用命令生成对应的.py文件。先从系统的cmd进入到ui文件的位置,然后输入命令“ pyside2-uic ****.ui -o ****.py ”进行文件转换:

运行正常。生成的py文件代码如下:

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

# Form implementation generated from reading ui file 'untitled.ui',
# licensing of 'untitled.ui' applies.
#
# Created: Mon May 11 20:42:28 2020
#      by: pyside2-uic  running on PySide2 5.12.6
#
# WARNING! All changes made in this file will be lost!

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:然后将生成的.py文件放到具体路径下,通过py进行加载,具体示例代码如下:

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_())

运行,结果如下图:
