配置PyQt5

打开PyCharm

Python Interpreter选择D:\Anaconda3\python.exe

打开Settings\Tools\External Tools

新建分组Qt5

Name : Qt_Designer
Group : Qt5
Programe : D:\Anaconda3\Lib\site-packages\pyqt5_tools\designer.exe
Working directory : $FileDir$

Name : Qt_Pyuic
Group : Qt5
Programe : D:\Anaconda3\Scripts\pyuic5.exe
Arguments : $FileName$ -o $FileNameWithoutExtension$.py
Working directory : $FileDir$

Name : Qt_Pyrcc
Group : Qt5
Programe : D:\Anaconda3\Scripts\pyrcc5.exe
Arguments : $FileName$ -o $FileNameWithoutExtension$_rc.py
Working directory : $FileDir$

新建项目

打开Tools\Qt5\Qt_Designer，新建文件，拖动一些控件，保存到你的项目路径，这边文件名为project.ui

关闭Qt_Designer,项目多了project.ui，右键Qt5\Qt_Pyuic,将project.ui转化成project.py

我的project.py内容如下:

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

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(480, 422)
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(160, 80, 93, 28))
        self.pushButton.setObjectName("pushButton")
        self.label = QtWidgets.QLabel(Form)
        self.label.setGeometry(QtCore.QRect(160, 190, 141, 71))
        self.label.setObjectName("label")

        self.retranslateUi(Form)
        self.pushButton.clicked.connect(self.label.clear)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.pushButton.setText(_translate("Form", "PushButton"))
        self.label.setText(_translate("Form", "TextLabel"))

新建一个python测试文件 : qt_test.py,内容如下:

import sys
from project import Ui_Form
from PyQt5.QtWidgets import QApplication, QMainWindow
if __name__ == '__main__':
    app = QApplication(sys.argv)
    MainWindow = QMainWindow()
    ui = Ui_Form()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

配置Python

PyCharm右上角，选择Edit Configurations

添加Python

Script path : 你的项目\qt_test.py
Python Interpreter : D:\Anaconda3\python.exe
Working directory : 你的项目路径

到此可以正常运行使用了。
