PyQt5 Label - Checking if label is widget type

PyQt5 Label - Checking if label is widget type

In PyQt5, to check if a label (or any object) is a widget type, you can use Python's built-in isinstance() function. This function allows you to check if an object is an instance of a particular class or a subclass thereof.

Since all PyQt widgets in PyQt5 inherit from QWidget, you can check if a label is a widget type by seeing if it's an instance of QWidget. Here's how you can do this with a label:

from PyQt5.QtWidgets import QApplication, QLabel, QWidget # Create an instance of QLabel label = QLabel("This is a label") # Check if the label is a widget type is_widget = isinstance(label, QWidget) print("Is label a widget:", is_widget)

In this example, is_widget will be True because QLabel is a subclass of QWidget.

This approach works for any PyQt5 widget, not just QLabel, since all standard PyQt5 UI components derive from QWidget.
