PyQt5 QDateEdit - Assigning Name Property

PyQt5 QDateEdit - Assigning Name Property

In PyQt5, if you want to assign a name (or any other property) to a widget like QDateEdit, you would typically use the setObjectName() method. This method allows you to give a widget a name, which can be useful for various purposes such as referencing it in stylesheets or finding it among parent widget's children.

Here's how you can assign a name to a QDateEdit widget:

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QDateEdit

app = QApplication(sys.argv)

window = QWidget()
layout = QVBoxLayout(window)

date_edit = QDateEdit()
layout.addWidget(date_edit)

# Assigning a name to the QDateEdit widget
date_edit.setObjectName("myDateEdit")

# Let's print the name to confirm
print(date_edit.objectName())  # This should print 'myDateEdit'

# Example usage in a stylesheet
stylesheet = """
    QDateEdit#myDateEdit {
        background-color: yellow;
    }
"""
app.setStyleSheet(stylesheet)

window.show()
sys.exit(app.exec_())

In the above code:

  1. A QDateEdit widget named date_edit is created.
  2. We use the setObjectName() method to set its name to "myDateEdit".
  3. As an example usage, we apply a stylesheet to color the background of date_edit based on its object name.

When you run the code, you'll see a QDateEdit widget with a yellow background, showcasing that the name property was correctly assigned and referenced in the stylesheet.
