配置Pycharm开发环境

打开Pycharm,新建一个项目

选择到你安装的python3.6.5对应的解释器,这步很关键!然后填好项目名称,然后点击【create】按钮即可。

然后从 【File】->【Settings】中选择Extenal Tools,如下图所示:

点击添加, QT Designer,PyUIC两个工具,它们的设置如下图:

C:UsersAdministratorAppDataLocalProgramsPythonPython36Libsite-packagesqt5_applicationsQtbindesigner.exe

-m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py

设置好之后,点击确认,从最上部 【Tools】->【Extenal Tools】中选择QT Designer 打开如下所示:

PyQy5快速开发测试

就可以直接通过pycharm调用 QT Designer来设计界面了!我设计的界面如下:

然后保存文件为 test.ui

右键test.ui 选择转换为python代码,得到的代码如下:

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

# Form implementation generated from reading ui file 'test.ui'

#

# Created by: PyQt5 UI code generator 5.15.1

#

# WARNING: Any manual changes made to this file will be lost when pyuic5 is

# run again. Do not edit this file unless you know what you are doing.

fromPyQt5 importQtCore, QtGui, QtWidgets

classUi_MainWindow(object):

defsetupUi(self, MainWindow):

MainWindow.setObjectName( "MainWindow")

MainWindow.resize( 800, 600)

self.centralwidget = QtWidgets.QWidget(MainWindow)

self.centralwidget.setObjectName( "centralwidget")

self.label = QtWidgets.QLabel(self.centralwidget)

self.label.setGeometry(QtCore.QRect( 80, 110, 591, 371))

self.label.setObjectName( "label")

self.label_2 = QtWidgets.QLabel(self.centralwidget)

self.label_2.setGeometry(QtCore.QRect( 80, 20, 91, 41))

self.label_2.setObjectName( "label_2")

MainWindow.setCentralWidget(self.centralwidget)

self.menubar = QtWidgets.QMenuBar(MainWindow)

self.menubar.setGeometry(QtCore.QRect( 0, 0, 800, 25))

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)

defretranslateUi(self, MainWindow):

_translate = QtCore.QCoreApplication.translate

MainWindow.setWindowTitle(_translate( "MainWindow", "OpenCV学堂-QT+OpenCV Python版本"))

self.label.setText(_translate( "MainWindow", "TextLabel"))

self.label_2.setText(_translate( "MainWindow", "OpenCV学堂"))

添加一段调用代码,

if__name__ == "__main__":

app = QtWidgets.QApplication(sys.argv)

MainWindow = QtWidgets.QMainWindow

ui = Ui_MainWindow

ui.setupUi(MainWindow)

image = QtGui.QPixmap( 'D:/images/lena.jpg')

ui.label.setPixmap(image)

ui.label.setAlignment(QtCore.Qt.AlignCenter)

MainWindow.show

sys.exit(app.exec_)

运行代码,测试结果如下:

从此再也不用担心我用Python不会写UI了

踩坑指南:

配置与加载QT Designer问题

VCRUNTIME140_1.dll无法找到问题!

搜索,下载这个文件,然后扔到 windows/system32下面就好啦,亲测有效。

2. 无法加载Platform问题,导致QT Desinger启动失败

需要把

C:UsersAdministratorAppDataLocalProgramsPythonPython36Libsite-packagesqt5_applicationsQtplugins

目录下的platform整个文件夹copy到

C:UsersAdministratorAppDataLocalProgramsPythonPython36Libsite-packagesqt5_applicationsQtbin

目录下,然后再启动就好啦
