Step1. 用Qt Designer设计一个想要的UI

Step2. 用pyuic5编译为py文件

运行cmd执行命令

> pyuic5 dlg_UI.ui > dlg_UI.py    # 也有下面这样的方式 {没有测试过}  > pyuic5 -o dlg_UI.py dlg_UI.ui  # 其中，-o [输出文件的名称] [生成的ui文件的名称]

此时我们得到了dlg_UI.py文件

# -*- coding: utf-8 -*-    # Form implementation generated from reading ui file 'dlg_UI.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(740, 294)          self.tableWidget = QtWidgets.QTableWidget(Dialog)          self.tableWidget.setGeometry(QtCore.QRect(50, 81, 601, 171))          self.tableWidget.setObjectName("tableWidget")          self.tableWidget.setColumnCount(4)          self.tableWidget.setRowCount(0)          item = QtWidgets.QTableWidgetItem()          self.tableWidget.setHorizontalHeaderItem(0, item)          item = QtWidgets.QTableWidgetItem()          self.tableWidget.setHorizontalHeaderItem(1, item)          item = QtWidgets.QTableWidgetItem()          self.tableWidget.setHorizontalHeaderItem(2, item)          item = QtWidgets.QTableWidgetItem()          self.tableWidget.setHorizontalHeaderItem(3, item)          self.btn_GetFile = QtWidgets.QPushButton(Dialog)          self.btn_GetFile.setGeometry(QtCore.QRect(330, 20, 75, 23))          self.btn_GetFile.setObjectName("btn_GetFile")          self.edit_dir = QtWidgets.QLineEdit(Dialog)          self.edit_dir.setGeometry(QtCore.QRect(50, 20, 271, 20))          self.edit_dir.setReadOnly(True)          self.edit_dir.setObjectName("edit_dir")            self.retranslateUi(Dialog)          QtCore.QMetaObject.connectSlotsByName(Dialog)        def retranslateUi(self, Dialog):          _translate = QtCore.QCoreApplication.translate          Dialog.setWindowTitle(_translate("Dialog", "Dialog"))          item = self.tableWidget.horizontalHeaderItem(0)          item.setText(_translate("Dialog", "选择"))          item = self.tableWidget.horizontalHeaderItem(1)          item.setText(_translate("Dialog", "路径"))          item = self.tableWidget.horizontalHeaderItem(2)          item.setText(_translate("Dialog", "文件编码"))          item = self.tableWidget.horizontalHeaderItem(3)          item.setText(_translate("Dialog", "转换编码"))          self.btn_GetFile.setText(_translate("Dialog", "获取文件"))

Step3. 继承一个dlg类

from dlg_UI import *  from PyQt5.QtCore import *  from PyQt5.QtWidgets import *      class listDlg(QDialog):      def __init__(self, name="Dlg"):          # 构造函数          super().__init__()          self.initUI(name)          self.cnt_tmp = 0          def initUI(self, name):          # 初始化函数          self.ui = Ui_Dialog()          self.ui.setupUi(self)          self.setWindowTitle(name)          self.initConnect()            def initConnect(self):          # 初始化信号与槽          self.ui.btn_GetFile.clicked.connect(self.slot_btn_getFile)          pass          def setDirEditText(self, str_show):          # 更新edit的文本          self.ui.edit_dir.setText( str_show )        # ######################      #        槽函数      # ######################        def slot_btn_getFile(self):          #btn_getFile的槽函数          self.cnt_tmp = self.cnt_tmp + 1          self.setDirEditText(str(self.cnt_tmp))            pass

Step4. show之

这就是主函数了

from listDlg import *  from PyQt5.QtCore import *  from PyQt5.QtWidgets import *  import sys    if __name__ == '__main__':      app = QApplication( sys.argv )      dlg = listDlg('转换文件编码')      dlg.show()      sys.exit(app.exec_())      pass
