In this article, I will tell you what is PyQt and how to install PyQt in python, and a hello world example implemented in PyQt. It will introduce both PyQt5 and PyQt6.
1. What Is PyQt?
- PyQt is an extensive collection of GUI tools and libraries for creating user interfaces for Python applications.
- PyQt allows developers to create highly customizable user interfaces that can be tailored to the specific needs of their applications.
- In addition to standard GUI creation tools, PyQt also includes a wide range of useful tools for creating custom widgets and dialogs.
2. How To Install PyQt In Python?
- Installing and using PyQt in Python is a relatively simple process.
- First, you need to make sure that you have Python installed on your system.
- You can check to see if you have Python installed by typing “python –version” in the command line.
- Once you have confirmed that you have Python installed, you can proceed with installing PyQt using pip.
- To do this, type “pip install pyqt5” into the command line.
- If you want to install PyQt6, you need to run the below command in the command line.
# Install the PyQt6 package pip install PyQt6 # Install the QtDesigner package pip install pyqt6-tools # Install the Qt.py package pip install qt.py
3. How To Use PyQt In Your Python Project?
- Once PyQt is installed, you can begin using it in your Python projects.
- In order to use PyQt in a project, you will first need to import it.
- To do this, type “import PyQt5” into your Python script to use PyQt5.
- If you want to use PyQt6, you should use the command import PyQt6 to import the PyQt6 modules and functions into your project.
- After this, you can begin creating your PyQt applications.
4. PyQt Hello World Example Code.
- Below is the basic hello world example that is implemented using PyQt5.
import sys from PyQt5.QtWidgets import QApplication, QWidget if __name__ == '__main__': app = QApplication(sys.argv) w = QWidget() w.resize(250, 150) w.move(300, 300) w.setWindowTitle('Hello World') w.show() sys.exit(app.exec_())
- Below source code use PyQt6 to implement the hello world example.
import PyQt6 app = QApplication() # Create a simple window window = QWidget() window.setWindowTitle('Hello World') window.resize(400, 300) # Create two labels label1 = QLabel('Label 1', window) label2 = QLabel('Label 2', window) # Set label positions label1.move(10, 10) label2.move(10, 50) window.show() app.exec_()
