In this step-by-step tutorial, you’ll learn how to use Qt Designer to create GUIs from your windows and dialogs and use them in your Python applications.

To create a GUI for your windows and dialogs in PyQt, you can take two main paths: you can use Qt Designer, or you can hand code the GUI in plain Python code. The first path can dramatically improve your productivity, whereas the second path puts you in full control of your application’s code.

GUI applications often consist of a main window and several dialogs. If you’re looking to create these graphical components in an efficient and user-friendly way, then Qt Designer is the tool for you. In this tutorial, you’ll learn how to use Qt Designer to create your GUIs productively.

In this tutorial, you’ll learn:

• What Qt Designer is and how to install it on your system
• When to use Qt Designer vs hand coding for building your GUIs
• How to build and lay out the GUI of an application’s main window using Qt Designer
• How to create and lay out the GUI of your dialogs with Qt Designer
• How to use Qt Designer’s .ui files in your GUI applications
