PyQt5 QDoubleSpinBox – Clearing the Text

PyQt5 QDoubleSpinBox is a widget that allows the user to input numerical values within a certain range. The user can clear the text using the built-in clear() function. In this tutorial, we will learn how to clear the text of a QDoubleSpinBox in PyQt5.

Setting up the environment

To follow along with this tutorial, it is assumed that you have a basic understanding of PyQt5 and have it installed on your system. If you do not have PyQt5, you can install it using pip.

Creating a QDoubleSpinBox widget

To create a QDoubleSpinBox widget, we can use the QDoubleSpinBox() class. We can set the minimum, maximum, and initial values using the setMinimum(), setMaximum(), and setValue() functions respectively.

spin_box = QDoubleSpinBox()
spin_box.setMinimum(0)
spin_box.setMaximum(99)
spin_box.setValue(50.0)

Clearing the text

To clear the text of a QDoubleSpinBox, we can call the clear() function of the widget. This function resets the value of the widget to its default value, which is 0.0 in the case of a QDoubleSpinBox.

Here's an example of how to clear the text using the clear() function:

spin_box.clear()

Conclusion

In this tutorial, we learned how to clear the text of a QDoubleSpinBox widget in PyQt5 using the clear() function. The clear() function resets the value of the widget to its default value, which is 0.0 for a QDoubleSpinBox.
