Back inI started working on a file manager called fman. It's a desktop application for Windows, Mac and Linux. You use it as an alternative to Explorer on Windows or Finder on Mac to browse folders, copy files, etc.
I chose this combination over Electron because Qt offers great performance and Python makes it easy to use. One of the hard parts of creating fman was packaging and deployment: Turning its source code into a standalone executable. Creating installers for Windows, Mac and Linux.
And automatic updates. To help others with this, I open sourced fman's build system. It saves you months of time when creating desktop applications with Python and Qt. It has thousands of stars on GitHub. It was featured on the Qt blogas well as in an official Qt webinar I was invited to give. To promote fbs, I wrote a tutorial about PyQt5.
This really took off. It's now read by many hundreds of people every single day. Maybe also you found this site through the tutorial! But that got me thinking: If so many people are interested in a PyQt tutorial, doesn't this mean that there is demand for a book about it? I researched which PyQt5 books are available. And I realized that they were all either outdated, or not very good. I felt that I could write a better one. So I sat down for hours and wrote this book.
He even agreed to write the foreword.
The book is the resource I wish I had had when I began working on fman years ago. It would have been a fantastic investment of both my time and money for jumpstarting fman's development. I want you too to be happy with this book.

Enjoy the book! Frequently asked questions. What do I receive upon purchase? You'll also get the full source code for the 15 sample applications covered in the book. I made sure that you can go through everything in a few hours, while gaining years worth of experience.This is a PyQt5 beginner tutorial. It will help you get up and running with PyQt in the shortest possible time. A basic knowledge of Python is assumed.
PyQt is best suited for development of non-commercial applications GPL licence. You will need the latest version of Python currently 3. Make sure this is installed and that you add the executable to the system path.
This option is automatically available from within the installer. Once that is done, download an appropriate binary from the Riverbank website and choose the default installation options. Line 4: QWidget is the base class of all user interface objects in PyQt5, so you are creating a new Form class that inherits from the base class, QWidget.
Lines The default constructor for QWidget. The default constructor has no parent, and a widget with no parent is known as a window. Lines We add a QGridLayout. QGridLayout lays the widgets out in a grid. Widgets can be positioned as shown using Cartesian co-ordinates.
Lines If nameLine contains no text we issue an alert. If there is some text in the variable, we issue another alert, this time including the string entered by the user. The rest of the code should be easy to follow. We create an instance of the Form object called screen. The show method will display the widget on screen.
We then begin the event handling loop for the application. The event handling loop waits for an event to occur and then dispatches it to perform some task. The event-handling loop continues to work until either the exit method is called or the main widget is destroyed. The sys. This was a very basic tutorial. A comprehensive reference can be found here.

This is Advanced PyQt5 e-book. This e-book is a tutorial which covers several interesting parts of the library.
The first chapter covers date and time. The examples demonstrate date and time arithmetic, show how to work with universal and local time, epochs, or daylight saving time. In the Graphics chapter, we do some basic and more advanced painting. The Graphics View framework chapter covers Graphics View framework, which is a high level framework to create graphics quickly and efficiently.
Layout management is considered to be one of the most difficult areas of GUI programming. Writers usually only skim the topic, covering the very basics of it. Based on my experience while writing a complete e-book dedicated to layout management, this chapter was a piece of cake. Once you know the principles behind the process, you can utilize them in other GUI toolkits too.
In this chapter you will learn everything important about layout management. In the Custom widgets chapter, we will show how to create three custom widgets: a Led widget, a CPU widget and a Thermometer widget.
As you expand your GUI using more widgets, you will cover networks, databases, and graphical libraries that greatly enhance its functionality. Next, the book guides you in using Qt Designer to design user interfaces and implementing and testing dialogs, events, the clipboard, and drag and drop functionality to customize your GUI.
You will learn a variety of topics, such as look and feel customization, GUI animation, graphics rendering, implementing Google Maps, and more. Lastly, the book takes you through how Qt5 can help you to create cross-platform apps that are compatible with Android and iOS.

PyQt5 refers to the most recent version 5 of Qt. You may still find the occasional mention of Py Qt4 on the web, but it is old and no longer supported. An interesting new competitor to PyQt is Qt for Python.
Its API is virtually identical. It's backed by the Qt company, and thus likely the future. We use PyQt here because it is more mature. The best way to manage dependencies in Python is via a virtual environment.
A virtual environment is simply a local directory that contains the libraries for a specific project. This is unlike a system-wide installation of those libraries, which would affect all of your other projects as well. To create a virtual environment in the current directory, execute the following command:. To activate the virtual environment on Windows, run:.
You can see that the virtual environment is active by the venv prefix in your shell:. The reason why we're using version 5. This version is guaranteed to work. Besides this subtlety — Congratulations! You've successfully set up PyQt5. Time to write our very first GUI app!
With the virtual environment still active, start Python. We will execute the following commands:. Next, we create a QApplication with the command:. Many parts of Qt don't work until you have executed the above line. You will therefore need it in virtually every Py Qt app you write. The brackets  in the above line represent the command line arguments passed to the application. Because our app doesn't use any parameters, we leave the brackets empty. The last step is to hand control over to Qt and ask it to "run the application until the user closes it".
This is done via the command:. If all this worked as expected then well done! Everything you see in a Py Qt app is a widget : Buttons, labels, windows, dialogs, progress bars etc. Like HTML elements, widgets are often nested. For example, a window can contain a button, which in turn contains a label. You can download the code for the app shown in the screenshot hereif you are interested. Like the example above, your GUI will most likely consist of multiple widgets.
In this case, you need to tell Qt how to position them. For instance, you can use QVBoxLayout to stack widgets vertically:.
As before, we instantiate a QApplication. Then, we create a window.
