3. 将.ui文件转换为python代码

  • 安装pyqt5模块 pip install pyqt5 或 pip3 install pyqt5
  • 转换文件 pyuic5 -o dialog.py dialog.ui 根据自身情况替换文件及路径

    下面是转换后的代码:
# -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'dialog.ui' # # Created by: PyQt5 UI code generator 5.10.1 # # WARNING! All changes made in this file will be lost! from PyQt5 import QtCore, QtGui, QtWidgets class Ui_Dialog(object): def setupUi(self, Dialog): Dialog.setObjectName("Dialog") Dialog.resize(640, 480) self.pushButton = QtWidgets.QPushButton(Dialog) self.pushButton.setGeometry(QtCore.QRect(370, 80, 113, 32)) self.pushButton.setObjectName("pushButton") self.lineEdit = QtWidgets.QLineEdit(Dialog) self.lineEdit.setGeometry(QtCore.QRect(140, 80, 113, 21)) self.lineEdit.setObjectName("lineEdit") self.textBrowser = QtWidgets.QTextBrowser(Dialog) self.textBrowser.setGeometry(QtCore.QRect(180, 200, 256, 192)) self.textBrowser.setObjectName("textBrowser") self.label = QtWidgets.QLabel(Dialog) self.label.setGeometry(QtCore.QRect(30, 80, 111, 16)) self.label.setObjectName("label") self.label_2 = QtWidgets.QLabel(Dialog) self.label_2.setGeometry(QtCore.QRect(30, 220, 141, 16)) self.label_2.setObjectName("label_2") self.retranslateUi(Dialog) QtCore.QMetaObject.connectSlotsByName(Dialog) def retranslateUi(self, Dialog): _translate = QtCore.QCoreApplication.translate Dialog.setWindowTitle(_translate("Dialog", "Dialog")) self.pushButton.setText(_translate("Dialog", "PushButton")) self.label.setText(_translate("Dialog", "这是Line Edit ->")) self.label_2.setText(_translate("Dialog", "这是Text Browser ->"))

使界面程序运行起来

  • 在生成的代码结尾添加如下代码,可使其运行:
def main(): """ 主函数,用于运行程序 :return: None """ app = QtWidgets.QApplication(sys.argv) dialog = QtWidgets.QDialog() ui = Ui_Dialog() ui.setupUi(dialog) dialog.show() sys.exit(app.exec_()) if __name__ == '__main__': main()
