PyQt5 is a toolkit for creating Python GUI applications. As a cross-platform toolkit, PyQt can run on all major operating systems (Unix, Windows (Mac).

To get started, download and install the community version of PyCharm: Mac Download (Open the downloaded.dmg file and drag PyCharm into your Applications folder) Windows Download (Open the downloaded.exe file and install PyCharm, using all the default options.) Once PyCharm finishes installing, go ahead and run the program. Once PyCharm is installed you should find it in your applications folder (Mac) or search for it in your Windows search box (bottom left-hand corner). In order to gain full functionality of PyCharm, you will want to register your product as a student license, which you should be able to accomplish from the 'Welcome to PyCharm' screen. Set up PyCharm and PyGame; see the cross-platform information below. Install Python 3.6.4 (If you have a different version of Python, you still must install 3.6.4 seperately!): Download the installer from python.org. Run the installer. Choose the “Custom Installation” option.

This article describes how to install Python + PyCharm + PyQt5.

With PyQt5, the GUI is designed in two ways:

• directly using the code to design the interface
• using QtDesigner to visualize the design, and then convert the resulting .ui file into a .py file.

Install Python + PyCharm + PyQt5.

Step 1. Install Python.

Visit the official website at https://www.python.org/ to download and install your target Python version.

Install PyQt5

Enter the cmd interface. Run the command and wait a moment.

The command is executed and PyQt5 is installed.

Test if pqyt5 is actually installed

Create a new file, example.py, and enter the following code.

After running, the following screen will pop up, indicating that PyQt is working normally.

3. Install PyCharm.

Install Pycharm On Mac

Visit the official website http://www.jetbrains.com/pycharm/
Choose download and install Community version.

PyCharm Basic Configuration.

Step 1 Create a new project

Step 2 Set the default PyCharm parser.

Select File Settings Project: first Project Interpreter, set Project Interpreter to The version of python you are using

Step 3 Adding third-party libraries

Stay in the Project Interpreter interface, click on the +, find and install pyqt5. pyqt5-sip, pyqt5-tools. After successful installation, the interface should look like this.

Step 4 Configuring QtDesigner

Install designer
You can start designer directly from PyCharm. Make sure designer is installed first. Designer is not installed with the pip installation.

On Fedora Linux you can do this:

Ubuntu Linux users can do thiS:

You can also do this:

Once qt5-designer is installed, you can configure it in PyCharm.

PyCharm select File Settings Tools PyCharm. External Tools, click + New Tools, Create QTdesigner and PyUIC tools

Configure two key parameters.

• Program: the path to your own designer.
  

  • Windows users can link to designer.exe, for example C:xxxxAppDataLocalProgramsPythonPython35-32Libsite-packagespyqt5-toolsdesigner.exe
    

  • Fedora Linux users can link designer-qt5
    

  • Ubuntu users can set it to /usr/lib/x86_64-linux-gnu/qt5/bin/designer

Install Pycharm Mac Terminal

• Working directory: $ProjectFileDir$

Step 5: Configure PyUIC

Install Opencv Pycharm Mac

Configure three key parameters.

• Program: Your own python.exe path For example, C:xxxxAppDataLocalProgramsPythonPython35-32python.

• Arguments:-m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py

• Working directory:$ProjectFileDir$

Test PyQt installation

From code

Now that everything is setup, it’s time to test if everything is setup correctly.
Create a GUI interface using the code below (or any PyQt code).

Select Run->Run first. You should see a PyQt window popup.

QTDesigner

Use QTDesigner to generate a GUI interface and convert it to a .py file using PyUIC.

Select Tools->ExternalTools->QTdesigner.

In the QT Designer interface, a GUI creation interface will pop up for the first time, click on create to automatically generate a GUI interface.

Save the interface as Untitled.ui file.

Back to the PyCharm project interface, there is an extra .ui file under the project list.

Right-click on Untitled.ui and select ExternalTools->PyUIC in the pop-up list.

Install Pycharm Community Edition On Mac

This will generate a Untitled.py file for Untitled.ui.
