PyQt5 QSpinBox - Accessing Suffix

PyQt5 QSpinBox - Accessing Suffix

In PyQt5, a QSpinBox is a widget that allows the user to choose from a range of integer values. The suffix is an optional string that can be displayed after the numeric value in the spin box. For instance, you might want to use this feature to show units such as "px" for pixels or "kg" for kilograms.

To access or retrieve the suffix of a QSpinBox, you can use the suffix() method.

Here's a simple example demonstrating how to set and then access the suffix of a QSpinBox:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QSpinBox, QLabel class AppDemo(QWidget): def __init__(self): super().__init__() self.initUI() def initUI(self): layout = QVBoxLayout() # Create a QSpinBox self.spinBox = QSpinBox(self) self.spinBox.setRange(0, 100) # Set a suffix for the QSpinBox self.spinBox.setSuffix(" px") # Retrieve and print the suffix suffix = self.spinBox.suffix() print("Suffix:", suffix) # Display QSpinBox in the layout layout.addWidget(self.spinBox) self.setLayout(layout) self.show() if __name__ == "__main__": app = QApplication(sys.argv) ex = AppDemo() sys.exit(app.exec_())

When you run this code, the QSpinBox will display values followed by the "px" suffix, and the program will print "Suffix: px" to the console.
