PyQt5 QSpinBox - Cleaning the text

PyQt5 QSpinBox - Cleaning the text

If you want to clean or clear the text of a QSpinBox in PyQt5, you can reset the value of the QSpinBox to its default or minimum value. The QSpinBox doesn't have a direct method like clear() as you might find in a QLineEdit, because it always expects a valid integer value.

However, if you just want to set the value of the QSpinBox to its minimum (or any default value), you can use the setValue() method.

Here's a simple example:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QSpinBox, QPushButton class App(QWidget): def __init__(self): super().__init__() self.initUI() def initUI(self): layout = QVBoxLayout() # Create a QSpinBox self.spin_box = QSpinBox(self) layout.addWidget(self.spin_box) # Create a button to clear the QSpinBox value clear_btn = QPushButton('Clear Value', self) clear_btn.clicked.connect(self.clear_spinbox_value) layout.addWidget(clear_btn) self.setLayout(layout) self.setWindowTitle('QSpinBox Clear Value Example') self.show() def clear_spinbox_value(self): # Setting the value of QSpinBox to its minimum self.spin_box.setValue(self.spin_box.minimum()) if __name__ == '__main__': app = QApplication(sys.argv) ex = App() sys.exit(app.exec_())

In this example, when you click the "Clear Value" button, the value of the QSpinBox is set to its minimum value, effectively "cleaning" the text shown in the QSpinBox. If you have a specific default value in mind, you can just replace self.spin_box.minimum() with your desired default value in the clear_spinbox_value method.
