The complete PyQt5 tutorial — Create GUI applications with Python

Easily create professional-quality desktop applications for Windows, Mac and Linux. Unlock the power of Qt5 from Python.

Welcome to the complete guide to building GUI apps with Python & Qt.

Learn how to use PyQt5 to create desktop applications with Python. Rapidly convert your scripts and utilities into professional apps, which you can share with others. PyQt and PySide both give you all the power of the Qt framework directly from Python, including complex widgets, multimedia support, 2D vector graphics and a flexible model-view architecture. This complete PyQt5 tutorial takes you from basic principles to complex applications.

Getting started with PyQt5

Take your first steps building apps with Python & Qt5

Like writing any code, building PyQt5 applications is all about approaching it in the right way. In the first part of the course we cover the fundamentals necessary to get you building Python GUIs as quickly as possible. By the end of the first part you'll have a running QApplication which we can then customize.

Creating applications with Qt Designer

Using the drag-drop designer to develop your apps

As your applications get larger or interfaces become more complicated, it can get a bit cumbersome to define all elements programmatically. The good news is that Qt comes with a graphical editor Qt Designer (or Qt Creator) which contains a drag-and-drop UI editor — Qt Designer. In this PyQt5 tutorial we'll cover the basics of creating Python GUIs with Qt Designer.

Build your own tabbed web browser with PyQt5

Now we've learnt the basics, we'll put it into practice building a real-life app. In this course we'll create a functional web browser using Qt5 widgets. Starting with the basics and then gradually extending it to add features like opening and saving pages, help, printing and tabbed browsing. Follow the tutorial step by step to create your own app, but feel free to experiment as you go.

Threads & Processes

Run concurrent tasks without impacting your UI

As your applications become more complex you may finding yourself wanting to perform long-running tasks, such as interacting with remote APIs or performing complex calculations. By default any code you write exists in the same thread and process, meaning your long-running code can actually block Qt execution and cause your Python GUI app to "hang". In this PyQt5 tutorial we'll cover how to avoid this happening and keep your applications running smoothly, no matter the workload.

ModelViews and Databases

Connecting your application to data sources

All but the simplest of apps will usually need to interact with some kind of external data store — whether that's a database, a remote API or simple configuration data. The Qt ModelView architecture simplifies the linking and updating your UI with data in custom formats or from external sources. In this PyQt5 tutorial we'll discover how you can use Qt ModelViews to build high performance Python GUIs.

Graphics and Plotting

Vector graphics and plotting using PyQtGraph

In addition to the simple bitmap graphics already covered, Qt provides API for vector graphics. Vector graphics can be used to build complex and interactive interfaces beyond the normal widget interface. They can also be used for plotting nice graphs with PyQtGraph. In this PyQt5 tutorial we'll introduce vector graphics and have a look at plotting data with PyQtGraph.

Custom Widgets

Designing your own custom widgets in PyQt

Widgets in Qt are built on bitmap graphics — drawing pixels on a rectangular canvas to construct the "widget". To be able to create your own custom widgets you first need to understand how the QPainter system works and what you can do with it. In this PyQt5 tutorial we'll go from basic bitmap graphics to our own entirely custom widget.

Packaging and distribution

Sharing your awesome applications with other people

There comes a point in any app's development where it needs to leave home — half the fun in writing software is being able to share it with other people. Packaging Python GUI apps can be a little tricky, but in this PyQt5 tutorial we'll cover how to package up your apps to share, whether commercially or just for fun.

QtQuick & QML

Building modern GUIs with QtQuick & QML

Qt Quick is Qt's declarative UI design system, using the Qt Modeling Language (QML) to define custom user interfaces. Originally developed for use in mobile applications, it offers dynamic graphical elements and fluid transitions and effects allowing you to replicate the kinds of UIs you find on mobile devices. Qt Quick is supported on all desktop platforms too and is a great choice for building desktop widgets or other interactive tools. Qt Quick is also a great choice for developing UIs for hardware and microcontrollers.
