软件版本与依赖
代码语言:javascript复制
下载与安装Pycharm专业版
下载与安装Python3.6.5
VS2015专业版(可选)

安装OpenCV与PyQt5

安装OpenCV4.4

代码语言:javascript复制
pip install opencv-python

安装PyQt5

代码语言:javascript复制
pip install pyqt5
pip install PyQt5-tools

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

代码语言:javascript复制
-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:

代码语言:javascript复制
# -*- 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.

import sys
from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(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)

    def retranslateUi(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,

代码语言:javascript复制
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

代码语言:javascript复制
C:UsersAdministratorAppDataLocalProgramsPythonPython36Libsite-packagesqt5_applicationsQtplugins

目录下的platform整个文件夹copy到

代码语言:javascript复制
C:UsersAdministratorAppDataLocalProgramsPythonPython36Libsite-packagesqt5_applicationsQtbin

目录下,然后再启动就好啦
