PyQt5 QSpinBox - Adding Prefix

To add a prefix to a QSpinBox in PyQt5, you can use the setPrefix() method. The prefix is a short piece of text that appears before the numeric value in the spin box.

Here's a simple example to demonstrate adding a prefix to a QSpinBox:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QSpinBox app = QApplication(sys.argv) window = QWidget() layout = QVBoxLayout(window) spin_box = QSpinBox() spin_box.setRange(0, 100) # Add a prefix to the QSpinBox spin_box.setPrefix("$ ") layout.addWidget(spin_box) window.setLayout(layout) window.show() sys.exit(app.exec_()) 

In this example, we've added a $ symbol as a prefix to the spin box. So, when you adjust the value, it will look like "$ 1", "$ 2", etc. This can be particularly useful when representing currency or other units.
