环境搭建

python环境

安装目录 : D:Anaconda3

添加以下目录到环境变量

D:Anaconda3

D:Anaconda3condabin

D:Anaconda3Scripts

安装PyQt5,pyqt5-tools,PyQt5-stubs

pip install PyQt5==5.12.1.0

pip install pyqt5-tools==5.11.3.1.4

pip install PyQt5-stubs==5.12.1.0

安装Python IDE

eric6(可选)

解压后安装 : python install.py install

使用智能IDE : PyCharm

配置PyQt5

打开PyCharm

Python Interpreter选择D:Anaconda3python.exe

打开SettingsToolsExternal Tools

新建分组Qt5

新建项目

打开ToolsQt5Qt_Designer，新建文档，拖动一些控件，保存到你的项目路径，这边文档名为project.ui

关闭Qt_Designer,项目多了project.ui，右键Qt5Qt_Pyuic,将project.ui转化成project.py

我的project.py内容如下:

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测试文档 : 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_())

PyCharm右上角，选择Edit Configurations

添加Python

Script path : 你的项目qt_test.py

Python Interpreter : D:Anaconda3python.exe

Working directory : 你的项目路径

到此可以正常运行使用了。
