What is Qt Designer?
Qt Designer is a tool for quickly building graphical user interfaces with widgets from the Qt GUI framework. It gives you a simple drag-and-drop interface for laying out components such as buttons, text fields, combo boxes and more. Here is a screenshot of Qt Designer on Windows:
Qt Designer produces .ui files. This is a special XML-based format that stores your widgets as a tree. You can either load these files at runtime, or have them translated to a programming language such as C++ or Python.
Qt Designer vs. Qt Creator
Qt Designer normally ships as a part of Qt Creator. This is Qt's official editor and lets you do a lot more than just graphically design user interfaces. It is a full-fledged and very powerful C++ IDE. This power comes at a price however: The download for Qt Creator is gigabytes in size!
This page was created for people who only need Qt Designer. The download links here contain minimal, self-contained installers of just Qt Designer that are orders of magnitude smaller. Here they are again:
Qt Designer and Python
Many people like to use Qt Designer together with Python because it is a dynamic language that lends itself well to rapid prototyping.
The easiest way to combine Qt Designer and Python is via the PyQt binding. To install PyQt, simply enter the following on the command line:
(This assumes you have Python 3 installed.)
Suppose you have saved your file from Qt Designer as dialog.ui. Then you can create another file, say main.py, with the following contents:
When you then invoke python main.py on the command line, your dialog should open:
If you want to learn more about combining Qt with Python, you may be interested in my book:
It distills years of experience to quickly help you create better GUI applications. I'm humbled to say that even Phil Thompson, the creator of PyQt, read it and thinks it's 'very good'.
Michael has been working with Qt and Python since 2016, when he started fman, a cross-platform file manager. Frustrated with the difficulties of creating a desktop app, Michael open sourced fman's build system (fbs). It saves you months when creating Python Qt GUIs. Recently, Michael also wrote a popular book about these two technologies.
Qt's support for different Windows platforms is extensive and mature.
Before you get started, ensure that your development environment fulfills the requirements.
To download and install Qt for Windows, follow the instructions on the Getting Started with Qt page.
