How to Create QPushButton in PyQt5

In this PyQt5 article we want to learn about How to Create QPushButton in PyQt5, PyQt5 is powerful and popular library for creating desktop applications with Python, there are different widgets in PyQt5, in this article we want to talk about QPushButton.

First of all we need to install PyQt5, for the installation you can use pip.

pip install PyQt5

1	pip install PyQt5

First of all we need to import the required classes and modules from PyQt5.

from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
import sys

1 2	from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton import sys

After that we need to create an instance of the QApplication class, which represents our application. This class manages the GUI event loop and handles application-wide settings. Add the following code.

app = QApplication(sys.argv)

1	app = QApplication(sys.argv)

In PyQt5 QMainWindow is the main window container in PyQt5. we will create an instance of this class and set its properties as needed.

window = QMainWindow()
window.setWindowTitle("QPushButton Tutorial")
window.setGeometry(100, 100, 400, 200)  # Set window position and size

window = QMainWindow()

window.setWindowTitle("QPushButton Tutorial")

window.setGeometry(100, 100, 400, 200) # Set window position and size

This code is used for creating QPushButton, also we have set the x,y, width and height of the button.

button = QPushButton("Click Me", window)
button.setGeometry(100, 50, 200, 50)

1 2	button = QPushButton("Click Me", window) button.setGeometry(100, 50, 200, 50)

To make our QPushButton interactive, we can connect a function to its clicked signal. This function will be executed whenever the button is clicked.

def button_clicked():
    label.setText("Welcome to geekscoders.com")

button.clicked.connect(button_clicked)

def button_clicked():

label.setText("Welcome to geekscoders.com")

button.clicked.connect(button_clicked)

And lastly we need to show the main window and start the application’s event loop.

window.show()
sys.exit(app.exec_())

1 2	window.show() sys.exit(app.exec_())

This is the complete code for this article

from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QLabel
import sys

def button_clicked():
    label.setText("Welcome to geekscoders.com")

app = QApplication(sys.argv)

window = QMainWindow()
window.setWindowTitle("QPushButton Tutorial")
window.setGeometry(100, 100, 400, 200)

button = QPushButton("Click Me", window)
button.setGeometry(100, 50, 200, 50)
button.clicked.connect(button_clicked)

label = QLabel(window)
label.setGeometry(100, 120, 200, 30)

window.show()
sys.exit(app.exec_())
