Installer Qt Designer sur Windows | Utilisation de Qt Designer avec PyQt et Python

Qt Designer is a powerful tool for creating user interfaces with PyQt and Python. In this article, we will discuss how to install Qt Designer on Windows and how to use it with PyQt and Python.

Installation de Qt Designer sur Windows

Before using Qt Designer, you need to install PyQt and Python on your Windows machine. You can download the latest version of Python from the official website and install it on your system. Once Python is installed, you can use pip to install PyQt by running the following command in your terminal:

pip install pyqt5

After installing PyQt, you can download the Qt installer from the official website and run it on your Windows machine. Follow the installation instructions and make sure to include Qt Designer in the installation package.

Utilisation de Qt Designer avec PyQt et Python

Once Qt Designer is installed on your Windows machine, you can start creating user interfaces for your PyQt applications. Qt Designer provides a user-friendly interface for designing and organizing your application’s GUI components.

To use Qt Designer with PyQt and Python, you can create a .ui file by designing your user interface in Qt Designer and saving it. Then, you can use the pyuic5 tool to convert the .ui file into a Python script. Here’s an example command to convert a .ui file to a Python script:

pyuic5 -x your_ui_file.ui -o output_python_script.py

After converting the .ui file to a Python script, you can import the generated module and use it in your PyQt application. Here’s an example of how to use the generated code in your Python application:


import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from output_python_script import Ui_MainWindow

class MyApp(QMainWindow, Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)

if __name__ == '__main__':
app = QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())


With this code, you can create a PyQt application that uses the user interface designed in Qt Designer. You can add event handlers and functionality to your application by modifying the generated Python script.

Overall, Qt Designer is a valuable tool for creating user interfaces with PyQt and Python. By following the installation steps and using the pyuic5 tool, you can easily integrate Qt Designer into your development workflow and create stunning user interfaces for your applications.
