PyQt5 QSpinBox - Setting Fixed Pitch

Setting a "fixed pitch" (or monospace) font for a QSpinBox in PyQt5 can be accomplished by setting a monospace font for that widget. You can do this using the QFont class and then apply it to the QSpinBox using the setFont method.

Here's an example to demonstrate this:

1. Create a simple PyQt5 application.
2. Set a monospace font for a QSpinBox.

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QSpinBox from PyQt5.QtGui import QFont class MainWindow(QMainWindow): def __init__(self): super().__init__() layout = QVBoxLayout() self.spin_box = QSpinBox(self) # Set a monospace font for the spin box font = QFont("Courier") # or "Monospace", "Consolas", etc. depending on your system and preferences font.setFixedPitch(True) self.spin_box.setFont(font) layout.addWidget(self.spin_box) container = QWidget() container.setLayout(layout) self.setCentralWidget(container) app = QApplication(sys.argv) window = MainWindow() window.show() app.exec_() 

In this example:

• A QFont object is created with "Courier" as the font family. "Courier" is a commonly available monospace font, but you might choose another monospace font depending on your system and preferences.
• font.setFixedPitch(True) ensures the font is set to fixed pitch.
• self.spin_box.setFont(font) sets the font for the QSpinBox.

When you run the application, you'll see that the numbers in the QSpinBox are displayed in a monospace font.
