What is Qt Designer?

Qt Designer is a tool for quickly building graphical user interfaces with widgets from the Qt GUI framework. Information technology gives you a uncomplicated drag-and-drop interface for laying out components such every bit 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 equally a tree. You tin can either load these files at runtime, or have them translated to a programming language such equally C++ or Python.

Qt Designer and Python

Many people like to utilize Qt Designer together with Python because it is a very productive programming language. The easiest way to combine the two is via PyQt or PySide6. To install PyQt, simply enter the following on the command line:

python3 -1000 venv venv source venv/bin/actuate # or "phone call venv\Scripts\activate.bat" on Windows python3 -m pip install PyQt6

(This assumes you have Python three installed.)

Suppose you accept saved your file from Qt Designer as dialog.ui. So you can create some other file, say master.py, with the post-obit contents:

from PyQt6 import uic from PyQt6.QtWidgets import QApplication  Form, Window = uic.loadUiType("dialog.ui")  app = QApplication([]) window = Window() form = Form() grade.setupUi(window) window.show() app.exec()

When you and then invoke python main.py on the command line, the GUI you created in Designer should open:

How you lot tin can create an installer

Once you've created an application with Qt Designer, you typically want to create an installer for information technology. On Windows, this is often an installation sorcerer in the form of an .exe:

On macOS, .dmg archives are commonly used:

We tin apply fbs to create such installers for applications based on Qt and Python. The free eddition of fbs supports Python 3.vi and PyQt5. Later versions require fbs Pro.

Once you lot've installed fbs, you can create an installer for the Python application from in a higher place as follows:

Run the command fbs startproject. This asks you a few questions near the name of your app etc. It creates the directory src/main/python. The command fbs run should at present requite yous a quick preview of the empty awarding created by startproject.

Change principal.py from before to the following:

from PyQt6 import uic from PyQt6.QtWidgets import QApplication          from fbs_runtime.application_context.PyQt6 import ApplicationContext          Class, Window = uic.loadUiType(appctxt.get_resource("dialog.ui"))          appctxt = ApplicationContext()          window = Window() form = Form() class.setupUi(window) window.show()          appctxt.app.exec()

Save master.py in src/main/python, overwriting the existing file there.

Create the directory src/primary/resources/base. Move dialog.ui from to a higher place into it. When y'all at present do fbs run, then yous should once again run into the GUI you lot created in Designer.

Run the control fbs freeze. This turns your Python (and Designer) code into a standalone executable that can be copied to other computers.

Then execute fbs installer. On Windows, you need to install NSIS first and identify it on your PATH. On Linux, yous demand fpm. But once y'all accept these prerequisites, fbs will magically create your installer. Congratulations!

Information technology distills years of experience to quickly help you create ameliorate GUI applications. I'1000 humbled to say that even Phil Thompson, the creator of PyQt, read it and thinks it's "very proficient".

Qt Designer vs. Qt Creator

Qt Designer normally ships every bit a role of Qt Creator. This is Qt's official editor and lets y'all 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 merely demand Qt Designer. The download links hither incorporate minimal, cocky-independent installers of simply Qt Designer that are orders of magnitude smaller. Hither they are over again:

Michael has been working with Qt and Python since 2016, when he started fman, a cantankerous-platform file managing director. Frustrated with the difficulties of creating a desktop app, Michael open sourced fman's build organisation (fbs). Information technology saves you months when creating Python Qt GUIs. Recently, Michael also wrote a popular volume about these two technologies.
