PySide2 on Raspberry Pi

PySide2 is a Python binding of Qt framework. It allows developers to create elegant and intuitive graphical user interfaces for their applications. In this article, we will discuss how to install and use PySide2 on a Raspberry Pi.

Installation

To install PySide2 on Raspberry Pi, we need to use the pip package manager. We can install pip using the following command:

sudo apt-get install python3-pip

Once pip is installed, we can install PySide2 using the following command:

pip3 install pyside2

This will download and install all the necessary packages required for PySide2 to run on Raspberry Pi.

Usage

Let's create a simple PySide2 application that displays a window with a button. When the button is clicked, it will print a message.

import sys
from PySide2.QtWidgets import QApplication, QWidget, QPushButton, QMessageBox

class Example(QWidget):

    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):

        btn = QPushButton('Click me!', self)
        btn.setToolTip('This is a PyQt5 button')
        btn.clicked.connect(self.showDialog)

        self.setGeometry(300, 300, 300, 200)
        self.setWindowTitle('PySide2 on Raspberry Pi')
        self.show()

    def showDialog(self):

        msg = QMessageBox()
        msg.setWindowTitle('Message')
        msg.setText('You clicked the button!')
        msg.exec_()

if __name__ == '__main__':

    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

In the example above, we create a new QWidget object named Example, which contains a QPushButton object. We connect the clicked signal of the QPushButton object to the showDialog method of the Example object. When the showDialog method is called, it creates a QMessageBox object and displays the message 'You clicked the button!'.

Conclusion

In this article, we discussed how to install and use PySide2 on a Raspberry Pi. We created a simple PySide2 application that displays a window with a button. When the button is clicked, it will print a message. By using PySide2, developers can create elegant and intuitive graphical user interfaces for their applications running on Raspberry Pi.
