PyQt5 offers the ability to incorporate buttons using its QPushButton class. This class is housed within the PyQt5.QtWidgets module. You can create a button by invoking the QPushButton constructor and passing the desired display text as an argument.
For integrating buttons into a PyQt5 application, it’s essential to modify the import line as follows:
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton
Within the initUI() function, insert the subsequent code:
button = QPushButton('PyQt5 button', self)
The QPushButton initializes the widget with the button text specified in the first parameter. The setToolTip method displays a tooltip when a user hovers over the button. The button’s position is then adjusted to coordinates x=100, y=70.
To register a button click, we need to implement the following method:
Then, connect the aforementioned method to the button click event like so:
The finalized PyQt5 button code is:
A visual representation of the PyQt5 button from the aforementioned code is displayed above.
